[QUOTE="mtwarych, post: 1769946, member: 70595"] We decided to forgo the 175 to 180gn bullets because we are using the AR's to hunt with and we got what we needed from the 165's. Also, try to stick with service rifle loads due to you and the rifle taking a beating from loads meant to be fired in bolt actions. The loads meant for bolt actions may lead to other problems like overgassing and failures to extract and eject due to the bolt opening before the chamber pressure is low enough and the bolt travelling too fast to function properly. One other powder I will work up in the AR's this coming year is AR-COMP. I use this powder in my 6.5 Grendel loads and it is so accurate I would like to run it in the 308's if I can find a better load than the H4895. As a matter of fact, now that I think back on the load work ups, my son's rifle is marked with 308Win and my rifle is marked 7.62X51, which may be the reason my son's rifle runs 2.5gns more powder than mine. His velocity is about 70fps higher than mine also. I see no reason why you would have any trouble loading the 175's and the 180's. All I will suggest is not loading to full 308 bolt action loads. Stick with the middle of the load ladder and you should be fine. My GII came from the factory very overgassed and the rifle didn't function or shoot very well. (The rifle beat the hell out of me and had troubles with bolt-overs and my brass was beat to $#!t) I installed an adjustable gas block and a 10oz heavy buffer. What I have now is a well behaved, very accurate gasser that is a pleasure to shoot. I recently installed an Omega 300 suppressor on it and believe it or not, the rifle shoots more accurately than it did before, I can't wait for pinecone hunting season to open when the snow is off the mountains, If I can see them, they're in trouble.
