    looking to convert LR-308 DPMS gen 1 .308 barrel to 6.5 prc

    Lots! It's been a couple years, so I've had lots of time to get it where it's at now. The feeding and cycling is flawless now, it's one hell of a platform in 6.5 PRC and 300 WSM. I've got a 7 SAUM barrel that I haven't tried yet, but it's time is coming soon.

    Hunting with an AR?

    Was going to shoot the first deer I saw. There were deer everywhere so I decided to hold off and see if anything else would come out. That's when this guy showed up, shot him at 50 yards with the 300 WSM. A bit overkill for that range, but it works regardless. Kaliber Tech KT10 Longbow 300...

    "Long Action" Semi-Auto Rifles - What's the consensus?

    My little project is still pretty new, but it's been a couple years since development first started. Honestly, the receiver itself has undergone little change, mostly cosmetic. During development, the biggest changes where with the mag release and bolt stop. The mag release dictates how high...

    7mm SAUM AR

    I'd might question the quality of the components used on that rifle at that price. Hell, the fact they say it's made out of 7075 billet aluminum (which is good stuff) has me wondering how they are that cheap. That stuff in bar form is very expensive, it's more than double the price of 6061...

    I figured it was on the low end since it was one of my starting loads, my manual says 47,600 psi with 58gr of IMR4350, Hodgdon says 54,900 psi with 59gr of H4350. This is for hunting, I wanted to be shooting at least 1" at 100 yards and the bullet going at or over 2750 fps with whatever was the...

    Finally got out and got a load developed, here's what I'm using so far: 300 WSM Norma Brass Also Hornady Brass 180gr Berger Elite Hunter 59gr H4350 CCI 250 Magnum Primers Averaging 2790 fps COAL 2.955 (about .010 off the lands) I'm not the best shot in the world, but managed to get a .73"...

    7mm SAUM AR

    I'm liking the builds guys, magnum ARs are always fun! I built one in 300 WSM and another in 6.5 PRC, both function flawlessly after ironing out the gas system. I use AICS mags, so bulging is not an issue, plus I have up to 2.98" of room to work with. I finally acquired some 7 SAUM brass, so...

    It's a 5oz buffer. I have a 9oz I'm going to try when I get out and shoot either today or tomorrow. The one load I quickly put together was 2840fps, 190 berger vld, 61.5gr of H4350. This load was a bit hot, and the recoil was more than I'd like. I currently have several loads put together...

    Magnum AR Project

    It's been awhile, but I finally got around to taking some pictures of the carbon fiber rifle. It's 10lbs 11oz (if I remember correctly) as it sits in the pictures. The side charging upper really makes this platform a lot better IMO. I've had 100% reliable ejection with this upper, very...

    Which short action magnum?

    ^This^ I've got both a semi auto 6.5 PRC and 300 WSM. The PRC with 147gr ELDMs is very very smooth to shoot, I could easily shoot it all day without it beating me up. The 300 WSM with 190gr Bergers is a bit harder on the shoulder, but it's an elk killer. Since I do a lot of hunting, I'm...

    Most of the parts were things I had laying around. The barrels I got from X-Caliber, I had a Magpul PRS lite stock and Magpul standard grip, Geissele Dual Stage trigger, Spuerlative Arms adjustable gas block. I have two bolts, one from KAK Industries and one that is modified (not sure what brand).
