    Source for steel E-type targets?

    Chris, this right here. Many schools use the IPSC profile instead of the Meter-tall E-type. More challenging but doesn't necessarily help teach or sustain mil-ranging to a cherry. I suppose all Gen-Z snipers carry two or three laser rangefinders now and no longer need boomer dot or hash...

    Woah... LMT & KAC quality/accuracy/performance

    Better is better. I read within the last few years that certain units have bought other brands (vice upgrade kits to legacy in-hand weapons) for turn-key fixes. This one caught my eye: https://www.outdoorlife.com/guns/seekins-sp10-review/ Manufacturers with military contracts must meet...

    No, not at all. Reinforcing that handloaders produce better than factory mass-produced.

    .308 Winchester

    I didn't go back through the entire thread. I like pictures. Maybe this will give some folks ideas for different loads: Match Kings and Tipped Match Kings: 168, 169, and 175 Match Kings: https://files.cartools.lv/ballistics/HANDLOADING_308WIN_Laurie_Holland.pdf

    In need of KRG Bravo chassis guidance

    I tried a Whiskey -- didn't like it. It felt like the butt / pistol grip style got in the way of functioning the bolt. Try both for your preference.

    First AR10/LR308 build.. Barrel questions

    You will probably want a 1-10 or tighter twist for 169 to 180/185 grain bullets. You'll need to launch them at 2550 fps or more.

    KAK 1n5 twist 11.5" v. 1n7 twist 11.5" , both suppressor ready, .076 GP.

    A 1-in-5 twist is typically for long, solid/monolithic copper bullets. They seat deeper into a 5.56 case so there's less powder to get the projo up to speed (you either crunch powder with a compressed load or go to a powder that trades volume for pressure). A faster twist makes up a little for...

    Chamber issue on Compass Lake built Aero M5

    The target does not lie. Yank the barrel, take the loss, get a new barrel done correctly.. Or not -- and accept your downrange performance and results. Cut-rifled Kriegers are generally much better than mass-produced "Consumer-grade" tubes.

    How to improve offhand accuracy with AR15

    This is the 200-yard standing slow fire and sitting rapid fire target scaled for 100-yard ranges. It is 21" x 21" a side. Put ten shots in ten minutes in the black (about the size of those 6" paper plates) at 100 yards and you've shot a 90 -- an expert score. It is challenging but NOT...

    How to improve offhand accuracy with AR15

    The sling is not used in international air or rimfire competition, in Conseil Internationale du Sport Militaire military rifle shooting, nor in Service Rifle. It takes a good firing position and lots of practice. It sounds counter-intuitive, but a heavier rifle helps prevent rifle movement and...

    History of the SR25

    Are you using an LMT big frame bolt stop? They're usually really reliable as far as function. This is an Armalite catch. If that little nose dingus isn't long enough it won't catch the follower tail. It's also got to be relieved enough it doesn't catch the inside of the upper when the...

    New (to me) Remington 40X

    When I was a kid we used to put Korean coins and quarters up against the berm and shot 'em. Made for nice little souvenirs with the bullet dent.

    New (to me) Remington 40X

    Measure groups with calipers using the two farthest shot holes -- from outside edge of grease ring to outside edge of the other, then subtract bullet diameter to give you a more precise reading (than guesstimating where hole centers might be). Mic your bullet diameter at the fattest part of the...
