[QUOTE="idaho elk hunter, post: 1054353, member: 68226"] Berger will be recommending a twist of 7.5 to 8 for the 195. I use to build many Weatherby 7mms to shoot the old Barnes 195 in Cold Alaska climates for those that wanted a long range Caribou and short range grizz package. The 1 in 8 always worked better. With a boattail and longer overall length I could reason that a 7.5 could be appreciated for a cold day and high barometer. A 8 twist is great to use the old 175 Gameking Sierra and the 195 Original Barnes. pushed to the max with H4831 and H 870 respectively. You would not believe how the 195gr 7mm would crumple a Grizz faster than a 300 Win. No matter where you hit it, it was always a complete pass thru smashing every bone in its way. The point I am making is when the 195 Berger comes out it should be a killer if pushed at a reasonable velocity. That's only if Berger does not have the inherit thin peeling jacket problem that they have had in the past. [/QUOTE]
