^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...

It's at around 9.5 pounds.

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).

I'll be using a simple 3 ribbed brake. I'm still debating on the scope, but I'm leaning toward a Leupold Mark 5 or US Optics FDN17. I'll post more once I get out shooting more, I can't wait to get some loads developed!

Never heard of Rifle Speed gas blocks, I'll give them a look. I'll be trying a heavier buffer as well. The only reason I ask about heavy optics is that I used to work for a company that sold big bore AR's. One of the customers could not get their gun to cycle and sent it back in to have us...

I finally found that a .077 gas port is the size that works best for the setup that I currently have. Dwell time still seems a bit quick since some of the rims are only very slightly raised, but not all of them. I currently have a 5oz buffer, I'm thinking a slightly heavier buffer will give me...

I've thought about buying a KAK upper and seeing how well it works with my receiver. Yes, 200gr is heavy for the 300 WSM IMO.

300 WSM, 22" barrel and 200gr Hornady ELDX. I realize they are hot loads, but I'd like to get reliable cycling with as much speed as possible. After that, I'll work on accuracy.

Velocity is 2820 fps

I tried the gun out this afternoon, here's what I found: With 2 rounds in the magazine, the bolt seems to short stroke. Sometimes it will eject the spent case at the 4-5 o'clock position, sometimes it will barely unlock from battery. It never picks up the next round, and I don't have a bolt...

New barrel with a .0625" gas port came in yesterday. Work's been busy, but I'm looking forward to getting it installed and trying it out soon.

Thanks for the info, I may have to experiment with this in the future. PM sent

Haven't had a lot of time to do some extensive testing, but here's a video I got of it last week. This is the 6.5 PRC upper, it works a bit better, but is still over gassed. I tried both the Griffin Armament +15% extra power spring, and standard AR 308 carbine spring, both seem to operate the...

Thanks for the replies. Here's a little bit more info on the current setup: The rifle has a milspec carbine buffer tube with a 22" barrel. The reloads are 200gr Hornady ELD-X with 60.5gr of H4350. I know it's at the upper end of things, but I want to make sure the system will work with...
