IMR® Legendary Powders now offers four (4) Enduron powders: IMR 4166, IMR 4451, IMR 4955, and IMR 7977. Shooters looking for readily-available alternatives to hard-to-find extruded powders should definitely check out the Enduron line-up. Precision shooters will find an Enduron option well-suited to most of the popular precision cartridge types. For example, IMR 4166 is a good replacement for Hodgdon Varget (commonly used in the .223 Rem, 6mmBR and .308 Win), while IMR 4955 is a fine substitute for H4831 (favored by F-Open shooters for the .284 Win and 7mm WSM cartridges).
Modern Powder Technology for Enhanced Performance
The technology in IMR’s Enduron line of powders provides four very important qualities that enhance both in-gun and downrange performance.
Copper fouling reduction – these powders contain an additive that drastically reduces copper fouling in the gun barrel. Copper fouling should be minimal, allowing shooters to spend more time shooting and less time cleaning a rifle to retain accuracy.
Temperature change stability – the Enduron line is insensitive to temperature changes. Whether a rifle is sighted in during the heat of summer, hunted in a November snowstorm or hunting multiple locations with drastic temperature swings, point of impact with ammunition loaded with Enduron technology will be very consistent.
Optimal load density - Enduron powders provide optimal load density, assisting in maintaining low standard deviations in velocity and pressure, a key feature for top accuracy.
Environmentally friendly - Enduron technology is environmentally friendly, crafted using raw materials that are not harmful to the environment.
The Enduron Line-Up of Four Powders
IMR now offers four Enduron powders that cover a broad range of burn rates. They are suitable for a wide variety of cartridges, from small varmint cartridges all the way up to the .338 Lapua Magnum.
IMR 4166 possesses the fastest burn rate in the Enduron lineup. It is the perfect burn speed for cartridges such as .308 Win, 7.62mm NATO, 22-250 Rem and 257 Roberts. A versatile, match-grade propellant, IMR 4166 is comparable to Hodgdon® Varget.
IMR 4451 is a mid-range burn speed powder, ideally suited for cartridges such as .270 Winchester, .30-06 and 300 Winchester Short Magnum. This powder is comparable to Hodgdon H4350.
IMR 4955 is a medium burn speed powder, falling in between IMR 4451 and IMR 7977 in burn speed. It provides top performance in big game cartridges such as 25-06, 280 Remington and 300 Winchester Magnum. This powder is comparable to Hodgdon H4831.
IMR 7977 has the slowest burn rate among the Enduron Technology powders. Its loading density is perfect for magnum cartridges and contributes to superb uniformity, yielding outstanding performance in 300 Winchester Magnum, 7MM Remington Magnum and .338 Lapua Magnum. IMR 7977 is comparable to Hodgdon H1000.
The Enduron Technology powders are available in one-pound (1 lb) and eight-pound (8-lb) containers from quality reloading retailers. Learn more about Enduron powders at www.enduronimr.com. For info on other IMR powders, visit www.imrpowder.com.
Take a look at that unusual target below. We bet you’ve never seen one of these before. It’s a 50-Yard Sighting Target for the M1 Garand. It’s designed to allow a rifleman to confirm his zeros for multiple yardages all the way out to 1000 yards. But importantly, he can establish those zeros at a very “short” shooting facility, since the target is positioned at a mere 50 yards.
Here’s how it works. The target is placed at fifty (50) yards. You start at the bottom, aiming at the black circle. Then check your come-up table and work your way up, clicking step-by-step to the various horizontal lines set for 200, 300, 500, 600 and 1000 yards. This is NOT “spray and pray” — you need to have a pretty good idea of the clicks you need, based on your ammo’s ballistics. This target is calibrated for the U.S. Military M72 Ball Ammo. The targets are available from Champion’s Choice ($0.75 each) or from Creedmoor Sports (12 for $5.95).
Lapua’s Kevin Thomas used this target to get zeroed for the recent D-Day Anniversary Match at the Talladega Marksmanship Park. Kevin used the target for both his M1 Garand as well as his M1903A1 Springfield, both chambered for the .30-06 Springfield cartridge.
Zeroing at a Short Distance — How to Use the 50-Yard Sighting Target, by Kevin Thomas
As part of my preparation for the Garand Match at the CMP’s Talladega Marksmanship Park, I needed to zero my new M1 Garand, but I was crunched for time. I didn’t have time to get to my normal range and confirm zeros at actual yardages. But a 50-yard zero target came to the rescue. Made for M1s using the M72 National Match ammo, the target allows the shooter to establish fairly good zeros at 200, 300, 500, 600 and 1,000 yards if you’ve got access to a 50-yard range.
I have no idea when these 50-yard Sighting Targets were first developed, but they’ve been around for at least as long as I’ve been involved in this game (longer than I care to admit). It consists of a tall target, with a smallish black bullseye located at the bottom center. The bullseye is an aiming point only. Extending through the top of the target is a vertical line that runs directly up the center, to nearly the top of the paper. Across this, there are intersecting horizontal lines that are marked 200, 300, 500, 600 and 1,000.
The target was designed for the M1 rifle using then-issued M72 National Match ammunition. This ammo launched a 173gr FMJBT bullet at approximately 2,640 fps. It was a good load in its day, supersonic out to the 1,000-yard line. While that ammo is fairly scarce these days, this isn’t a problem for the handloader. My standard match load for the M1 Garand utilizes the 175gr Lapua Scenar HPBT, and delivers remarkably similar ballistic performance. Thus my normal Garand load translates nicely to this 50-yard target. Yes, this is by design. No point in reinventing the wheel when Lake City has already established what works!
In use, the shooter sets the target up at a measured 50 yards, and (this is critical) checks the vertical line with a plumb bob or a carpenter’s level, to ensure that it is absolutely vertical. Once the target is set, the rifle is fired and the group noted. From there, it is a simple matter of zeroing it normally to bring the groups into alignment with the vertical line, at the elevation needed for a particular range. Once your group is hammering the intersection of the vertical line and the horizontal line marked “200”, you have established your 200-yard zero for that rifle. Record the number of clicks, and you’re good to go. Raise the impacts up to coincide with the line marked “300” and you now have a 300-yard zero as well. And so on, right up the target. Record those settings in your data book, and you’re ready to go to the range at the full distances. If done carefully, you may be in the X-Ring, but at the very least, you’ll be well-centered and ready to get some hard dope recorded for future shoots.
The same target can also be used with an M14/M1A, at least at the shorter distances. The ballistics of the M118 and the current M118LR are similar enough that this will get you on target at the full distances, probably requiring just a half MOA or so change from the 50 yard zero you recorded. Same bullets, moving at a slightly more sedate 2,550 fps, you’ll be in the ballpark at least.
Bryan Litz has recently popularized the short-range zeroing methods once again, reintroducing it to a new generation of shooters that may not have been aware of the old M72 short-range zero target. The same principles apply, and with the advent of the myriad computer ballistics programs and chronographs on the market today, any shooter can rapidly develop his own zero targets to accomplish the same result. But in the meantime, especially with the M1’s resurgent popularity, it’s nice to know that there’s an easy way to do things without a trip to a full-length range. The modestly-priced 50-Yard Sighting Targets can be ordered through Champion’s Choice or Creedmoor Sports.
Oh, and when I arrived in Talladega, yes, my zeros were good! All’s well that ends well. Safe Shooting! — Kevin Thomas

Can you hit an egg at 1230 yards? Nancy Tompkins can. It did take her a couple of shots though. Mighty impressive shooting by a great lady, the first-ever female to win the National High Power Championship. Nancy was shooting at Ireland’s Midlands National Shooting Centre. She took six shots to hit a clay pigeon, and then hit the egg two shots later. Here’s the official proof:
Nancy, along with daughter Michelle Gallagher, has been in the Emerald Isle competing at a series of matches at Midlands. Hosted by the NRA of Ireland (NRAI), the Emerald & Ireland Long Range Challenge is held annually at the Midlands National Shooting Centre of Ireland (MNSCI) in late May and early June. The event starts with the Long Range Challenge at 1100 and 1200 yards. That is followed by the Emerald match. In past seasons, the Emerald match included three yardages (800, 900, and 1000 yards) with a shoot-off for the top 10 competitors.
Nancy says she loves to shoot in Ireland — the facilities are excellent and the wonderful hospitality of her Irish hosts makes the experience memorable. Here’s a photo from the Midlands Shooting Centre, located in Tullamore, Ireland.
Here is the view from 9500 feet ASL. The SRS in 7mm Rem SAUM almost outran the Swarovski laser…
7mm RSAUM in a bolt-action bullpup? Yes it works. A talented shooter, who calls himself “ColdboreMiracle” in social media, has a Desert Tech SRS bullpup rifle chambered for the 7mm SAUM, and it hammers. The 7mm Remington SAUM (Short Action Ultra Magnum) is popular with F-Open competition shooters. It can also work well for long-range hunting and tactical tasks. Learn more about the 7mm Remington SAUM in our 7mm Cartridge Guide.
ColdboreMiracle explains how he selected the 7mm Rem SAUM chambering for his Desert Tech SRS Bullpup: “I just did a comparison between barrel life, velocity, brass, etc. and came to the SAUM. I can tell you this, if you go with one for your SRS, make sure you use long bullets like the 183 or 195, and seat them long. That will aid in smooth cycling.”
Mr. ColdboreMiracle tested the new generation 183gr Sierra MatchKings (item # 1983). These impressive projectiles are “tipped” at the factory. Claimed G1 BC is a lofty 0.707 (at 2300 fps and above). We have heard other reports that these bullets “hold waterline” exceptionally well at 1000 yards. That indicates the bullet-to-bullet BC is very consistent. No doubt the factory uniforming/pointing of the bullet tips helps in that regard.
As you can see, these 183-grainers shoot well in ColdboreMiracle’s SRS rifle. Here are five shots at 100 yards. That’s very impressive for a tactical-style rifle shot from a field-type bipod.
ColdboreMiracle says: “This is the only reason I need to shoot Sierra bullets. On the right (above) you can see the results of the 183gr SMK from my 7mm SAUM. Five shots at 100. A huge thanks to Mark at Short Action Customs, LLC for [chambering this barrel] for my Desert Tech SRS.”
ColdboreMiracle says the bullpup design has many advantages: “The Stealth Recon Scout (SRS) rifle from Desert Tech is a bullpup-configured precision rifle with a shorter length than many carbines. The SRS has a multitude of barrel options that can be swapped in under a minute — all of them come with a 1/2-MOA accuracy guarantee and return to zero. The SRS’s bullpup design puts the rifle’s COG closer to the shoulder, making the rifle balance better off-hand. The straight-line geometry of the SRS makes recoil seem lighter, and barrel hop is reduced, allowing the shooter to stay on target better. It takes a little getting used to, when converting from a traditionally-configured bolt gun. But once you do, you won’t go back.” To learn more about this rifle (and other Desert Tech arms), visit ColdboreMiracle’s Facebook Page and YouTube Channel.
7mm Remington SAUM — Key Considerations
In some respects, the 7mm SAUM cartridge may be better than the 7mm WSM. The 7mm SAUM holds less powder — but that’s a good thing, since the capacity is more than adequate to do the job. You can drive the 180s at 3000 fps with a SAUM using less powder than with a WSM. Additionally, the SAUM case has a slightly longer neck. This gives you greater flexibility in bullet seating. With a long neck you can set the throat so the long 180+ graing bullets are above the neck shoulder junction, yet you can still seat shorter hunting bullets close to the lands. Additionally, long case necks, some believe, cause less throat erosion than shorter necks. That’s not “hard science” but it is certainly a view shared by many experienced shooters. The long neck is one reason many varminters favor the 6mm Remington over the .243 Winchester.
7mm RSAUM Is More Efficient than 7mm WSM
7mm RSAUM shooter Steven Ikeeda tells us: “I decided that some type of 7mm was the ticket for doing well at 1000-yard matches, especially if one could drive the high-BC bullets at 2900+ fps. Looking over various 7mm cartridges that could produce those velocities (and didn’t require case-forming), I was impressed by the 7mm SAUM and the 7mm WSM. According to the load manuals, the 7mm WSM offered a bit more velocity than the 7mm SAUM. However, to achieve its small velocity advantage, the larger 7mm WSM had to burn 7-10% more powder than the 7mm SAUM. (The 7mm WSM has 81.0 grains of capacity vs. 73.6 grains for the 7mm SAUM.) The SAUM is a very efficient case. It looks like a 6.5×47 Lapua on steroids.”

Here’s a great gift for Father’s Day that any dad with a truck should appreciate. Forum member John Niemi crafts custom hitch covers that look like the end of a cartridge case, complete with head-stamp. Costing $75.00 (delivered), they are made out of solid brass with a stainless steel “primer”. The diameter of the brass is 4 inches and the engraved letters are about half an inch tall. The section that slides over the trailer hitch is aluminum, so you don’t have to worry about rust.
The “headstamp” can include your favorite cartridge-maker and caliber (wildcats too!), or you can include the name of your business. John tells us: “I can engrave any text on one as long as there is enough room for it. Turn around time is usually less then a week after payment. I have sold many of these and everyone has been extremely happy with the quality and workmanship that I put into my product. These make great one-of-a-kind gifts.”
$75.00 Delivered in the USA
The current price for brass bullet hitch covers from John Niemi is $75.00 shipped anywhere in the USA. To order, send email to JohnNiemi [at] charter.net or call (503) 440-1954. John said he should be able to offer pretty quick turn-around, unless he just gets swamped this week.

FFL required for purchase.
The 2016 Summer Olympics in Rio de Janeiro, Brazil are coming up soon. The Rio Olympic Games will include rifle, pistol, and shotgun competitions. Shooting events will be held in Brazil’s ultra-modern Olympic Shooting Center, originally created for the 2007 Pan-American Games at a cost of $53.5 million. Perhaps the most challenging Olympic rifle discipline is the 50m three-position (3P) smallbore match. In this article, American Olympian Matt Emmons provides expert tips on three-position shooting.
Here Matt Shows the Kneeling Position. The other two positions are Standing and Prone.
Matt Emmons will compete in the Three-Position Event at the Rio Olympics, seeking his fourth Olympic medal. Rio marks Matt’s fourth Olympic appearance — he has competed on the U.S. National Team since 1997, medaling in three Olympic games: Gold in 2004 in Men’s 50m Prone; Silver in 2008 in Men’s 50m Prone; and Bronze in 2012 in Men’s 50m 3X40. Although his specialty is Men’s 3-Position rifle, Emmons’ World Championship and Olympic Gold are in Men’s 50m Prone. He usually shoots an Anschütz or Bleiker .22LR rifle, with Eley Tenex ammo.

Three Sets of Hardware for Three Positions
You may be surprised to find that Matt often totes three complete sets of rifle parts to important matches — three buttplates, three cheekpieces, and three Centra sights with adjustable irises. Matt told Shooting Sports USA that he travels with “three sets for three positions. Our final is so fast that I need three sets of everything to allow a fast change-over between positions.” Matt carries his gear in an an Anschütz sport bag: “It’s similar to the big Ogio duffels with wheels, but lighter. I’ve worked with AHG/Anschütz for many years and I like their bag because all of my junk fits in it.”
Emmons, who will be competing in Rio this upcoming August, also carries something for good luck: “My wife Katy gave me a little figurine of a Czech fairytale character a long time ago for good luck and I always have it with me when I shoot.”
