[QUOTE="bigbulls, post: 1216720, member: 87413"] This is what happened when I switch to 195 Bergers. I have a custom gun with 26" barrel, when shooting 180 gr vld bergers the barrel was a 1&9 twist, and now I had new barrel installed 1&8 twist everything else stayed the same with the gun. I don't shoot hot loads these 2 loads are middle of the range, no pressure signs even in the 80-90 degree heat. The 180 vld load was shooting 3140 fps with sd being under 10 and less than 1/2 moa group at 100 yards with H1000 powder. The 195 berger load is 3060 fps with sd under 9 and less than 1/2 moa group at 100 yards with N570. I gave up 80 fps and .3 moa across the ranges out to 1000 yards but I gained 200 lbs of energy which is what I was after. In the end I don't think it was worth it but it's what I wanted and I'm happy. Just food for thought for others looking at changing to something different. [/QUOTE]
