22-250 1:12 twist Questions

[kgpcr]

I pick up my rifle on Saturday and I am going to start loading some ammo. I have a huge stash of Sierra 60grn hollow points and 60grn Nosler Ballistic Tip bullets. I have been told they will not shoot well with a 1:12 twist. Any one out there load 60grn bullets with a 1:12 twist with good results? any loads that work well? Thanks for the help!!!

they'll be fine.

work up some h-380 or rl-15 or win 748 loads and go impress yourself.

The .22-250 was designed as a high velocity varmint round, so light bullets approaching 4,000 fps were common. I have one with a 1/12 or 1/14 twist and it shoots 55 gr. ballistic tipped bullets with no problems. It isn't the weight of the bullet as much as it is the length. Also higher velocity will give greater spin. You are just going to have to try different weight bullets. I used IMR 4064 on the 55 gr bullets with good results, for heavier bullets, possibly use a slower powder. I have been using Hogdon Extreme powders recently, they are temperature stable, eliminating pressure problems when hot, something to consider in a varmint caliber when large numbers of rounds may be fired.
