[QUOTE="benchracer, post: 898354, member: 22069"] From the shooting I have done so far, the 350 SMK works just fine in a 12 twist. The SMK is about .1.750" long. I have shot the Cutting Edge 300g MTH and it stabilized with no problem in a 12 twist. It is 1.723" long. Cutting Edge states that their 330 grain MTH will stabilize in a 12 twist. It is 1.864" long. Given that even a 330g mono metal bullet will stabilize in a 12 twist, I have a difficult time imagining a cup and core 300 grain bullet that would not stabilize in a 12 twist. From what I can tell, a cup and core bullet would have to be well north of 350 grains before it would not stabilize in a 12 twist. I would think it would take a case at least equivalent in size to a .378 Weatherby before it would be possible to push a heavy enough cup and core bullet for twist to become an issue. Existing 300 grain .375 bullets are so blunt, I don't think it would take a lot to significantly increase the bc. I would add that I believe it possible to go up to 325 grains or so, if that is necessary to get a decent bc, before it would start to have a negative impact on the smaller cased .375's. After giving it more thought, I am seriously considering having a removable muzzle brake installed on my .375, mostly for shooting .350's from the bench. I don't think I would need it in the field. I also find myself wondering how effective a brake is on a .375. I suspect it will not be particularly efficient, but if it just takes the edge off recoil from the bench, I would expect that to be enough. [/QUOTE]
