[QUOTE="benchracer, post: 1421475, member: 22069"] Even when I had a 14 twist, I never bothered with anything lighter than 50 grains. I tried 55 Bergers, 55 SBK, 55 VMAX, and 60 grain Hornady Spire Points. They all stabilized, but none of them shot well. I had decent results with 50 VMAX and 52 AMAX in the 14 twist, but felt like there was more to be had. In my 12 twist, the 50 and 55 VMAX shot well, along with the 55 SBK, but I quickly went to the 53 VMAX and stopped shooting the others. Surprisingly enough, the 69 SMK also shot well and could be driven to around 3600 with the right powders, but with a much reduced bc. The 53 VMAX has proven to be the best overall combination in the 12 twist. My next barrel will be a 9 twist. I have seen reports that the faster twist barrels (up to 8 twist) still shoot the 53 VMAX (and heavier) with excellent accuracy. See the following conversation: [URL]https://www.longrangehunting.com/threads/22-250-twist-rate.197820/[/URL] The 53 VMAX is .830 in length. If you plug that information into something like the Berger calculator, it spits out a twist recommendation around 1:9.75. Though I do not consider that to be gospel, it goes a long way toward explaining the positive results being seen in 8 and 9 twist 22-250's. [/QUOTE]
