[QUOTE="264MHC, post: 2059641, member: 111161"] Ok so I’ll go back to my recommendation of 7-300 Norma. I would personally go with an improved Variant to reduce case stretch so you can run up the pressure some in addition to the extra capacity. I would think it gains a good bit going from a 20* to 35-40* shoulder in addition to .010-.015 larger shoulder dimension. You would probably be fine with 50 Pieces of brass the way you are going to use it and it takes at least that many to break in the barrel and level out velocity, so just do your fireforming then. Even with 190s and the barrel long throated for them, you should be able to Mag feed and have as much capacity as a 338 Lapua based case at the same COAL. Use either a Wyatt’s 3.8” CFE 12 box or AICS 338 Lapua CIP mags. I think the 190 LRHT would be the best bullet choice because they have the thicker Target Jacket to handle the speed and essentially the Same BC (.384 G7) as the 195s. I have some on order but haven’t seen them yet, but others have said the tips are more open than the SMKs and you can assure terminal performance by running an .040 wire drill bit through them. I would still go with an 8 Twist but try to get a 5r barrel since they’re supposed to stress the jacket less. Again the way you’re planning to use it I would probably go with Ramshot LRT for powder because it should be slow enough for top velocity and you won’t have to worry about powder bridging. Not sure on temp stability but just work up your load in conditions similar to what you will hunt in and you should be fine there.
