Using the Giraud Power Trimmer — Smart Video from Erik Cortina

Forum member Erik Cortina recently launched his own YouTube Channel dedicated to precision reloading and accurizing. Erik’s videos demonstrate the proper use of specialized reloading tools and provide helpful hints. Erik’s latest video is about the “mother of all brass trimmers”, the Giraud powered case trimmer. Erik says: “It you do volume reloading… this is the only trimmer to get. It not only trims to length but it also chamfers your case mouth inside and out.” In his video, Erik offers some very clever and useful tips that will help you get the most from your Giraud.

The Giraud trimmer is very precise. When set up correctly, it can trim brass with amazing consistency. In the video, Erik trims 5 pieces of brass in 15 seconds (6:32 mark). He then measures all five with precision calipers (7:00-8:08). All lengths are exact within .0005 (half a thousandth). Erik notes that the Giraud trimmer indexes off the case shoulder. As long as you have fire-formed brass with consistent base-to-shoulder dimensions, you should get very consistent trim lengths.

The secret to the system is a 3-way cutting head. This cutter can be swapped in and out in a couple minutes with wrenches provided with the kit. Erik has three different heads; one each for 6.5mm, 7mm, and .30 caliber. The video shows how to adjust the cutting heads to match caliber diameter (and to get the desired amount of inside/outside chamfer).

To trim and chamfer cases, you simply insert them nose-first into the cartridge-specific case-holder. Erick offers a smart tip — He uses a die locking ring to position the cartridge holder (3:15). This can be locked in place. Erik says die locking rings work much better than the hex-nuts provided by Giraud (with the hex-nut, one must re-set cut length each time you change case-holders.)

The Giraud can be used in either horizontal or vertical modes. Erik prefers to have the trimmer aligned vertically, allowing him to push cases down on the trimmer head. But the trimming unit has twin sets of rubber feet, allowing horizontal or vertical orientation.

Improved Case-Holder Made with Chamber Reamer:
For his .284 Shehane, Erik had to create his own case-holder (Giraud does not make one for that wildcat cartridge). Erik used his chamber reamer. To his surprise, Erik found that the brass was easier to trim in the custom case holder (compared to the Giraud-made spring-loaded holders). With a perfect fit, trimming and case extraction went more smoothly and the process was easier on his hands. (See 9:00-10:00). Based on Erik’s experience, you may want to create your own custom case-holder.

Trim Bullet Meplats Also
With a special bullet-holder fitting and meplat cutter head, the Giraud power trimmer can be used to trim bullet meplats. Trimming meplats can help make the Ballistic Coefficents of a batch of bullets more consistent. Uniforming meplats is also often done as a first step in the process of “tipping” bullets to improve BC.

Championship F-Class Form — Shiraz Shows How It’s Done

Shiraz Balolia F-classAt the Canadian F-Class Championships last week Shiraz Balolia won the F-Open Individual Championship, and Shiraz was a member of the winning Team USA America Match Team, and the winning USA 4-man F-Open team. If you want to see how a world-class F-Open pilot works his magic, check out this video. After a discussion of scoring, the shooting starts at the five-minute mark in the video. Under the guidance of wind coach Gary Rasmussen, Grizzly Industrial President Shiraz Balolia shoots 100-7X for ten shots, following Gary’s wind calls.

NOTE: Shiraz shot with wind coaches in the team matches at the Connaught Range in Canada. However, during the individual championship matches he had to make his own wind calls, dialing windage corrections or holding off as he saw fit. It wasn’t easy. Shiraz told us: “It’s been a while since I had 5 1/2 minutes of left wind on my .300 WSM and was holding left 3+, then holding right 3 1/2 just two shots later!”

Pair Firing in Canada
According to Shiraz, “One thing that was different about the Canadian Nationals was that they were pair fired. One shoots, other scores, other shoots, and so on. With this slower, pair method of shooting, every shot can be in a different condition. Unlike the USA Nationals where a guy can rattle off the whole string in less than 4 to 5 minutes in one or two conditions, you would be hard pressed to get off two or three shots each in five minutes. This is the way the next World Championship is going to be shot — with pair firing.”

Team Shooting with a Coach
F-Class Open Team shooting with Shiraz Balolia at 700 yards .284 7mmShiraz tells us: “We come across a lot of shooters who have never shot under a coach. This video was produced to give shooters a basic understanding of shooting with a coach and the importance of releasing a good shot. In a team setting, you basically leave all the decision-making to the coach and aim where you’re told to aim. I’ve worked with Gary many times and it shows in the comfort level we have with each other. The coach plots the shots or a plotter advises the coach of any grouping that is not centered.”

At the Canadian Championships, Shiraz used a .300 WSM. In this demo video, Shiraz was shooting a 7mm F-Open rig: “My .284 Shehane rifle takes about 10 to 12 shots to settle down and that is probably why we made several scope adjustments while shooting. It is a great caliber and a step up from a straight .284 Winchester. The wind was relatively calm, but sometimes that slow wind with subtle angle changes can be very deceiving.”

How to Win at 1000 Yards — IBS National Champ Tells All

Henry Pasquet IBS 1000 yard Nationals champion two gun overall .284 shehaneYes old dogs can learn new tricks. Just five years ago Forum member Henry Pasquet (aka “HenryP”) got started in 1000-yard benchrest shooting. He was 66 at the time. Henry worked hard, learned fast, and pursued accuracy with a vengence. That all paid off when Henry won the 2013 IBS 1000-yard Nationals this summer, finishing as the Two-Gun Overall National Champion. Henry was kind enough to talk about his rifle, his reloading methods, and his strategy for success. In fact, Henry was eager to share “everything he knows, so that other guys can fast-track their learning process”. Henry told us: “I want to share every lesson I’ve learned, so that other guys can improve their game and enjoy the sport more.” Henry also wants to encourage other senior shooters: “If you pay attention to details (when reloading), and get a good rifle with a good barrel, age is not a handicap. With a good set-up, older guys can compete with anyone out there. This is one sport where you can be a champion in later life.”

Q&A with Henry Pasquet, IBS 1000-Yard National Champion

Q: First, do you have any advice for older shooters getting started in their golden years?

Henry: You’re never too old. In this sport, you can excel even in your 60s, 70s and beyond. At this stage in life, we now have the time and money to get good equipment and rifles. Plus, our years of work experience help us to think, analyze, and thereby make progress. In this game, we older guys can definitely compete on a par with younger shooters.

HARDWARE

Q: Tell us about your Nationals-winning rifle and bench gear. Is there anything unique about your hardware that gave you an edge?

Henry: At the Nationals, I used my 17-lb Light Gun for both Light and Heavy Class. This rifle has a 1.55″, round BAT LP/RE action, fitted with a Bartlein barrel chambered for the .284 Shehane (an improved version of the .284 Winchester). The barrel was near-new; this was the first time I had used it this year. A great barrel and great batch of Berger 180gr VLDs all made a difference. Jay Cutright chambers my barrels. Jay’s metal-work is so precise that I can screw any barrel he’s chambered to any BAT action I own. The laminated stock was modified by Tommy Shurley from a standard 3″-wide fore-end to a 5″-wide True-Trac with an adjustable 3″-wide rear plate. It’s not pretty but it tracks like a Heavy Gun stock. Tommy made my other stocks as well.

Protektor sand bag 3M material IBS 1000 yard Nationals champion two gun overall .284 shehaneOn top is a Nightforce 12-42x52mm Benchrest scope with CH-3 reticle. I used a Fulghum (Randolph Machine) front rest with an Edgewood bag made with the low-friction 3M material. In the rear I use a special-order Protekor rear “Doctor” bag with ears spaced 3 inches apart. The rear bag also has the new 3M material on contact surfaces (photo at right).

Q: During the Nationals, at the last minute you switched guns. Why did you go from a 6mm Dasher to a 7mm Shehane?

Henry: I had planned to use my Light and Heavy Dashers, but after placing the Dasher on the ready line, decided to switch to the .284 Shehane. It was still early in the morning and I felt that the heavier bullets would be easier to see against the berm. The Dasher had actually been giving tighter groups under perfect conditions, but seeing the impact is important.

Q: Tell us about the combined tuner/muzzle brake on some of your barrels. How does this improve rifle performance and how do you set the “tune”? Do you tune the barrel to the load?

Henry: I use a tuner or tuner/brake on every barrel. I started with Time Precision tuners. Art Cocchia advised getting a load with a good known accuracy node with minimum extreme spread, which controls vertical. Do not go for the hottest loads, which just reduces brass life. Then use the tuner and tune the barrel to the load. The .284 Light Gun needed a muzzle brake and tuner. I had a local gunsmith cut a thread on the muzzle brake for a tuner I got from Sid Goodling. (Eric Bostrom developed an almost identical unit at the same time. I use Eric’s tuner/brakes on all my new barrels.) Just before Nationals, I tried going up and down one marker. Down one mark cut the group in half! Think how much range time (and barrel life) that saved me. Using a tuner is easier than messing around changing loads and tweaking seating depths. Tuners definitely can work. Last year I shot a 3.348″ 10-shot group at 1000 with my .284 Win Heavy Gun fitted with a Time Precision Tuner.

Q: What are the advantages of your stock’s 5″-wide fore-end and 3″-wide rear plate? Is there a big difference in tracking and/or stability? Does the extra width make the rifle easier to shoot?

Henry: I had true Heavy Guns with 5-inch fronts and 3-inch rears. They tracked well. I felt the same result could be had with a Light Gun. I talked two stock makers into making them. I initially had the standard rear stock until Tommy Shurley and Mike Hearn came out with an adjustable rear plate. The stocks track perfectly. You can see your scope’s crosshairs stay on the target the whole time and push the rifle back for the next shot. There is no torquing (gun wobbling) when cycling the bolt. Us old guys need all the help we can get. I am getting rid of my 45-pound Heavy Guns and replacing them with Light Guns with heavy barrels.

Q: Some people say the .284 Shehane is not as accurate as the straight .284 Winchester. You’ve proved them wrong. Why do you like the .284 Shehane? More speed, less pressure?

Henry: The reason I rechambered my 7mm barrels to .284 Shehane was not velocity, pressure, or brass life. It was all about bolt lift. My straight .284 almost required me to stand up to eject brass. I damaged an extractor and had to send the bolt back to BAT. With the .284 Shehane, my bolt cycles like there is no case to eject.

Reloading Methods

Q: People want to know about your load and your loading methods. What can you reveal?

Henry: For my .284 Shehane at the Nationals, I loaded 52.5 grains of Hodgdon H4350 and Federal BR-2 primers behind Berger 180gr VLDs. I usually anneal the brass each winter. I have used the same brass for years. I use Redding bushing dies, apply Imperial sizing wax, resize, wipe off wax, clean and uniform the primers pockets using the RCBS Trim Mate Case prep center, then apply Imperial dry neck lube with a bore mop.

K & M arbor seating force dial gaugeTo dispense powder, I use a RCBS ChargeMaster set 0.1 grain below my desired load and then weigh them on a Sartorius GD-503 magnetic force restoration scale to get identical charges. I use a K&M Arbor Press with seating force gauge when seating the bullets with a Wilson inline die. My “target” seating force on the K&M dial is 20-23 units for Dashers and 35-40 units for the .284 Shehane. I put any variables aside for sighters. I do not weigh brass, bullets, or primers. My bullets were so consistent that I did not sort by bearing surface. I did trim the Berger VLDs to the shortest bullet length with a Hoover Trimmer, and then pointed the meplats just enough to close them with a Whidden pointer. I sort my bullets to 0.005″ overall length, rejecting about five percent.

Q: What kind of precision are you looking for in your reloads? Do you trickle to the kernel? Does this really help reduce extreme spread?

Henry: I try to keep my charge weights consistent to one kernel of powder. I use the Omega powder trickler with a Sartorius GD-503 lab-grade balance to achieve that. For accurate dispensing, put very little powder into the Omega so you can drop one kernel at a time. Single digit ES (Extreme Spread) is the goal. This does make a difference at 1000 yards. If you get the same push on the same bullet with the same neck tension, good things are going to happen.

Q: You believe consistent neck tension (i.e. grip on the bullet) is really important. What methods are you using to ensure consistent bullet release?

Henry: I apply Imperial dry neck lube to the inside of my case-necks with a bore mop. The K&M arbor with seating force gauge shows the need to do this. If you put a bullet into a clean case, it will be jerky when seating the bullet. You may see 40 units (on the K&M dial) dropping to 20, then slowly increasing pressure. I explained to a friend that not lubing the neck is like overhauling an engine without lubing the cylinders. Smooth entry gives the bullets a smooth release.

Barrel Cleaning

Henry Pasquet IBS 1000 yard Nationals champion Carb out Carb-out WipeOut .284 shehaneQ: You go 60-80 rounds between cleaning and the results speak for themselves. What is your barrel cleaning procedure? Do you think some guys clean too often or too aggressively?

Henry: I cringe when I see people wearing out their barrels with bronze brushes between relays. I clean my barrels at the end of each day when I get home. I shot my best-ever 1K Heavy Gun group (3.348″) at day’s end after 60 to 80 rounds. After trying other solvents, I have gone back to Wipe-out’s Carb-Out and Patch-Out products. I use about four patches of Carb-Out, let it sit a few minutes, then use one stroke of a nylon brush followed by Patch-Out until the barrel is clean. I use a bore mop to clean inside the chamber, then some Break Free LP on the bolt followed by bolt grease on the lugs and cocking part. I use a bore guide when anything goes down the barrel.

Shooting Skills and the Learning Process

Q: Henry, you can shoot long-distance on your own property in Missouri. How important is practice, and what do you do during a typical practice session?

Henry: I can shoot 1000 yards on my farm. I have a concrete bench using a slab from a yard furniture place on concrete blocks. Two 4 x 8 sheets of plywood hold four IBS targets. I never practice. I only test, keeping a notebook with all the info. I do most of my testing at 300 to 500 yards, shooting off my deck so I can see my shots immediately.

Protektor bag benchrest rifle Light gun IBS 1000 yard Nationals champion two gun overall .284 shehane

Q: How much of your success do you credit to really accurate rifles, versus superior shooting skills?

Henry: I do not consider myself another Carlos Hathcock or some master marksman. I am an average 1000-yard shooter, but I do work hard getting the most out of my rifles. Four other people have shot their first 1000-yard matches with my rifles, including my wife, and all of them won relays! I loaned my Dasher to another shooter two years ago and he got second at the 600-yard Nationals. Others will tell you that the rifle must be “on” to win. If your barrel or bullets are average, don’t expect to perform above average in competition.

Q: What you do enjoy most about long-range benchrest shooting? What are the attractions of this sport?

Henry: The sport offers good people and a real challenge. 1000-yard shooting keeps us all humble, but we still keep trying to see how good we can do. I am thankful for Robert Ross providing the only match location that I can shoot regularly.

Q: Henry, you have been a Forum member for many years. Have you learned important techniques from other Forum members and other shooters?

Henry: I have followed the AccurateShooter Forum since 2008. At my age I am not good at computers. I copied and analyzed many articles, especially on the .284 and the Dashers. Without AccurateShooter.com, I would probably still be shooting double-digit (10″+) groups at 1000 yards, and I sure wouldn’t have my name on a National Championship trophy.

Q: You are in your 70s now and have only been shooting competitively for a few years. How did you get so good so fast? How did you manage to beat shooters who are decades younger?

Henry: I had 20/10 vision when I was young, but am down to only 20/20. I have been interested in long range shooting for a long time including ground hog hunting. I went to some VHA jamborees also. In 2008, I went to the Williamsport Benchrest School with a friend from Pennsylvania, John Haas. We would compare notes frequently. I bought a BAT three lug from Tom Mousel in Montana. We also compared notes and made each other better. At IBS matches I studied other shooters’ equipment and techniques. I tried some, accepting some and rejecting some.

Here’s my advice:
Always be ready to learn something new. If it makes sense, try it. I would also encourage other older shooters not to quit. Stick to it. You can make enormous progress in a few seasons.

Results from Arizona and California Long-Range Championships

Over the past couple of weeks, State Long-Range Championships were held in California and Arizona. Many of the best shooters in the Western States were in attendance. In both CA and AZ, State titles were awarded in both High Power and F-Class disciplines.

California Range Coalinga

California State Long-Range Championship, November 6-7, 2010
On November 6th and 7th, the California Long-Range Championship was hosted at the Coalinga Range. In the High Power division, Trevor Hengehold shot a brilliant match to finish first, and win the Championship, with a 795-36X score. Jim O’Connell was second with 783-37X which also earned him the High Senior Title. Dennis Flaherty had the next highest score (779-30X), and just two points behind Dennis was Gary Eliseo with 777-24X.

In the F-Class Division, Jerry Tierney, shooting his new 7mm RSAUM, won the championship with a 790-36X Score. Hot-shooting Brenda Hill took second with 780-31X, and Peter White was third with 773-19X. Though he had almost no time to practice with his RSAUM prior to the match (it was chambered the weekend before), Jerry was delighted with the gun’s performance: “This is the most accurate long-range rifle I’ve ever shot. And that’s saying a lot. I did get some load development help from Danny Biggs, who uses the same cartridge.” Jerry was shooting the new 7mm Berger 180gr “hybrid” bullets, with sorted Remington RSAUM brass, CCI BR2 primers, and Hodgdon H4831sc powder. The bullets were seated about 0.015″ off the lands and Jerry told us his load was running “real close to 3,000 fps”.

F-Class Jerry Tierney

Jim O’Connell Reports: “Congratulations to Trevor Hengehold and Jerry Tierney, the two new State Champions (High Power and F-Class). Trevor started out in front and never looked back. Jerry posted some good scores on Sunday to come from behind for his victory. This was the last of the Big Coalinga matches for 2010. We get started early in 2011 with the State Fullbore Match in February (26-27) and the State Palma Match in March (5-6). We are planning on awarding F-Class titles at all the State prone Championships (Fullbore, Palma, and Long Range) in 2011.”

Arizona Long-Range Championship, November 20-21, 2010
At the Ben Avery Shooting Facility outside Phoenix, many of the best shooters in the Western states congregated last weekend for the season-ending Arizona Long-Range Championship. Conditions were challenging but the top competitors managed to master the switchy winds and post high scores. In the High Power Division, the match winner and new AZ State Champion is Rick Curtis. Congrats to Rick! Curtis finished with an impressive 986-45X Grand Agg, after posting a 591-24X Iron Sights Agg, and a 395-21X “Any Sights” Agg. Eddie Newman, the High Senior for the match, posted the next highest Aggregate score, a 985-37X. Phil Hayes also shot a 985 but with 34Xs. Middleton Tompkins followed Hayes with a 979-36X. Peter Church was next with a 974-43X (second highest X-Count), and our Contributing Editor German Salazar finished with 973-34X.

F-Class Erik CortinaIn the F-Class Division, twenty-one shooters vied for honors. In F-Open, Texan Erik Cortina won the Championship with an impressive 972-17X. Charles Gooding was close behind with a 970-27X. Charles had high X-Count among all F-Class shooters. Freddy Haltom, shooting as a “Expert” had the third-highest score, an impressive 962-25X. Next in line was Tony Mangold with 944-19X.

F-Open Champ Cortina offered this report: “I was able to pull it off last weekend and win the Arizona State LR F-Open Championship at Ben Avery. The winds were strong and switching, making it very challenging! We ended up shooting 5×1000 instead of 6×1000 as scheduled. On Sunday, we only shot two strings as the third was canceled because of rain. I was shooting my .284 Shehane with 180gr Berger VLD bullets. My winning gun is a switch barrel 6.5×47 Lapua / .284 Shehane built by Mark Pharr of Tumbleweeds Custom Rifles. This Lawton 7500-actioned gun is the same rifle I used to set Club Records at the Bayou Rifle Club in Houston: 600-49X at 300 yards, and 595-34X at 1000 yards.”
