[QUOTE="bigngreen, post: 851815, member: 13632"] The issue with what your trying to do is once your at the 6.5 WSM level you right on the edge of the very best bullets start coming apart so you have to go to heavy bonded or copper bullets, you loose more BC so you have to drive them harder to make up for poorer ballistics, the harder you drive them the more finicky things become, the more shooting and tuning you have to do and you'll find yourself at a level that at 300 rounds of barrel life you don't know the ballistics of the round because you haven't had a repeatable load. The 300 Norma would a poor choice, it so massively over bore you will have significant powder bridging issues, the RUM class case has seen a 6.5 but I think that ended in only a couple hundred rounds and while it had some brief moments it could not maintain anything. The STW capacity seems to be the top end of what the bullets and barrels can handle, 6.5-300 Win mag is also up there, a guy could blow the shoulder out and improve it as well. IMO thee best 1000+ yard ballistics comes from bullet development, by a 1000 yards velocity starts playing less of a role and bullet BC takes over. [/QUOTE]
