Sunday GunDay: Costello Battles Storm Hannah with .300 WSM

Gary Costello England UK F-Class .300 WSM Win Short Magnum Speedy BAT Action SG Rifles

Gary Costello recently won the Great Britain National League 600-yard Championship in F-Open class. Gary managed that impressive win despite Storm Hannah which caused torrential rain and 40 mph winds during the match, held at the Diggle ranges. Gary, a Forum member, reports that conditions were hellacious: “The weather was terrible, with horizontal rain and winds in excess of 40 mph. In fact, some shooters got blown clean off the target and many complete misses occurred.”

There’s a special story here, as Gary had been battling a life-threatening illness for many months. Gary told us: “This was my first National Competition since September 2018. I contracted a serious heart virus in October 2018. I was critically ill until January 2019. After undergoing treatment and 100% rest I recovered slowly, my focus was the 600-Yard Shoot in April. I am now 70% there and hopefully in another 4-6 months I hope to make a full recovery.” [Editor: Gary, we are glad you are on the road to recovery.]

In today’s Sunday GunDay story, we feature Gary’s American-crafted .300 WSM F-Open rifle. Note that Gary’s rifle has a Ezell barrel tuner and a recoil-reduction system in the buttstock. The .300 WSM does generate quite a kick with those big .30-caliber bullets.

BAT M Action and Cerus Stock
This rifle was purchased from Jim Fowler (FalconPilot on the AccurateShooter Forum). This SG Rifles gun, crafted by smith Thomas “Speedy” Gonzalez, is a .300 WSM with BAT ‘M’ action (with nitrided bolt) and Cerus riflestock. Gary owns two other Speedy-built rifles.

Gary tells us: “My BAT ‘M’ action is a multi-port so I feed with my left and it ejects on the right. Speedy has worked on the firing control and timing, and I fitted the roller-cocking piece to aid smoothness and speed.” The fluted shroud is Speedy’s signature for fire control work.

Stunning Lenzi Co-Axial Front Rest
Gary tells us this impressive joy-stick rest “is a superb piece of engineering .. made by my good friend Alberto Lenzi.” Note the large stable base, and the deluxe counter-balance weight on the front end. Gary also uses a very nice leather rear sandbag crafted by Lenzi.

.300 WSM Load Details — H4350 with Berger 215gr Hybrids
Gary was shooting pointed Berger 215gr Hybrid bullets in Norma .300 WSM cartridge brass. The powder was Hodgdon H4350 with Muron KVB7 primers. Gary say his load runs around 2850 fps, and is very accurate. To demonstrate, here is a three-round, 100-yard test target, with a group measuring in the ones. Pretty impressive for a big bullet and a short magnum cartridge.

The UK has some wonderful places to shoot. This photo was taken at Blair Atholl in the Highlands of Scotland. Gary says “This is one of my favorite ranges and probably the hardest range to shoot in the UK. Due to the topography of the range you have to alter elevation as well as wind for pick-up and let-off. They say ‘Diggle Ranges Bark’ but Blair Atholl Bites!”

Blast from the Past — At Blair Atholl Ranges in Scotland

Gary Costello Blair Atholl Scotland Ranges

One of Europe’s very best F-Class competitors, Gary is no stranger to the winner’s circle. Here he is at the Blair Atholl Ranges in Scotland after a major victory a few seasons back. Gary says: “Blair Atholl, in the Estate of Blair Castle, is very scenic. The range is very tricky and is known as the hardest range in the UK to shoot due to the location of the targets cut into the hillside and valley. When the wind is at full value you often have to add one-half MOA elevation to every 1 MOA of wind. So thinking wind and elevation every shot is very difficult. I won this match some time ago and I do not recall the score. However it was a decisive win, and all matches in the competition were held at 1000 yards.” Gary was using a different rifle, but it also was a .300 WSM with a BAT action. His load was Hodgdon H4831 with Berger 215gr Hybrids, Murom primers, and Norma brass.

GB 600-Yard Championship — Gary’s Shot-by-Shot Report

The event was the first GB National League event of the year, our only short range (600-yard) match. This is actually one month later than usual in hope the weather would be better, sadly that wasn’t the case!

I won the Championship, five points clear of runner-up Ian Boxall. My final score was 241-18V out of a maximum of 250. The course of fire was reduced due to Storm Hannah on Saturday. It was decided by our committee that for safety we should shoot under cover (Diggle has a 600-yard covered firing point). The goal was to get at least one match to allow the competition to continue on the Sunday.

When I saw the condition and the flags I decided I needed to shoot as quick as possible as wind speed and direction were changing in seconds….

So I shot like stink only watching one flag and the other targets and my shot indication on the target screen. My first sighter was a score One left (a FIVE on the U.S F-Class target). But after adjusting, my second sighter was a One right — so there were pick-ups and let offs of about FIVE MOA!

I split the difference and went for score, my first shot was a Four (Nine on USA target) which I then adjusted on and held accordingly for the rest of the string using the other targets as indication and the one flag I had identified, it went pretty well.

Day Two (Sunday) weather was completely different, much better with no rain. We were first up at 0900 and the winds were light with subtle changes. This was a two sighters and 20-shot match, I started well with two V sighters which were converted, my partner Richard Sharman also had a good start and we proceeded through the string shooting Vs and Fives until Richard’s shots started to not register, this happened three times so it was decided I would continue and Richard would shoot again on another target. This caused a lot of delay and disruption. I had lost my path and wind, due to the delay I was allowed a non-convertible sighter which was a Three. It took two further shots to get back into the swing and I then recovered and ended the shoot with a 97-10V.

For the Final Match, the wind had picked up and was causing quite a few lost points and curses. I knew I was three points clear going into this Final Match so I had to play it real safe not to drop shots and lose critical points. I favored a left 4-5 Ring hold so not to get caught on the pick-ups. I use the March MTR-2 reticle, on 40X this reticle is subtended at exactly one-half MOA and brackets the F-class target perfectly. I was not concerned about the V bull at this time, the plan paid off and I dropped two points only.

6.5 Creedmoor Load Data from Sierra Bullets

Sierra Load Data 6.5 Creedmoor

The 6.5 Creedmoor cartridge is now one of the most popular cartridges for new factory rifles. Ruger, Savage, Howa and other gun-makers all offer 6.5 Creeemoor rifles. The 6.5 CM has been a leading cartridge for tactical/practical gun games (although many shooters have moved to a 6mm Creedmoor or even a 6mm Dasher). It offers excellent ballistics, moderate recoil, and good accuracy with a variety of powder and bullet combos. Along with the 6.5×47 Lapua, the 6.5 Creedmoor has demonstrated that a .264-Caliber mid-sized caliber is truly a jack of all trades — it can be accurate on paper, win PRS matches, and also harvest game during hunting season. If you own a 6.5 Creedmoor (or plan to get one) and hand-load your ammo, this post should provide a good start. Sierra Bullets now offers 6.5 Creedmoor Load Data for bullets from 120 to 142 grains — the most popular weight range for this chambering.

Sierra 6.5 Creedmoor Load Data Manual reloading .264

Sierra Bullets has released very complete load data for the popular 6.5 Creedmoor cartridge. This medium-sized cartridge has become one of the most popular chamberings for tactical and PRS shooters. The 6.5 Creedmoor combines excellent accuracy, good mag-feeding, good barrel life, moderate recoil, and reasonable component cost. That’s why this cartridge has caught on quickly.

The Springfield M1A is now available in 6.5 Creedmoor. For Gas Guns like this, be sure to full-length-size your brass after every firing, with adequate shoulder bump.
M1A 6.5 Creedmoor Sierra Load Data

Sierra Load Data 6.5 CreedmoorDeveloped in 2007 by Dennis DeMille and Dave Emary, the 6.5 Creedmoor is a shortened and improved 30 TC cartridge case that was inspired by the .308 Winchester design. This short action design was created to maximize case capacity and a wide range of loading lengths, while still fitting in standard short action magazines. With the correct twist barrel, the versatile 6.5 Creedmoor can take advantage of the wide range of bullet weights available in 6.5 mm (i.e. .264 caliber).

Reloaders should keep in mind that the 6.5 Creedmoor works best with medium to medium-slow powders such as H4350, Reloder 16, Varget, and IMR 4451. The light recoil and adaptability of the efficient 6.5 Creedmoor cartridge has already proven itself in high power and PRS matches, and in the hunting fields. Couple that with respectable barrel life and its intrinsic accuracy potential and you have a recipe for success.

Here are three tables from the Sierra Bullets Reloading Manual (5th Edition). IMPORTANT — This is just a sample!! Sierra has load data for many other 6.5mm bullet types, including FB, Spitzer, SBT, HPBT, and Tipped MK from 85 grains to 142 grains. To view ALL 6.5 Creedmoor DATA, CLICK HERE.
