TRader,
over stabilization isn't my concern. The rifle I'm plannning is an NRA Prone rifle. I'll have to shoot it from a sling and there are no muzzle breaks allowed, so WSM is out.
My concern is that in order to push the 176's and even 180's to 2800fp, I'll get too much pressure using the faster 1:8 twist, and I'll end up at 2700fps or there about. This would still be a great cartdridge, but wouldn't give me the numbers I'm looking for.
I'm wondering now if I do go with 1:8, will it shred Bergers or the new Sierra's? If Bob's supplies dry up for a couple months, I can't afford to wait, so I'll have to have other options, and the 8 twist may limit me.
Am I over thinking this?
