Optimum twist rate for 221 Fireball?
« on: February 22, 2014, 09:32:06 PM »
I am posting this in several forums at once, so please excuse me if you see it more than once.

Does anybody know or have any experience with 221 Fireball regarding the best twist rate for the widest range of bullet weights in a 22" rifle barrel?  I have not found any definitive answers, as most I have read concentrate on this cartridge in handgun length barrels.  As I understand, that length makes a difference along with bullet shape and velocity.

Any help would be appreciated.  Comments, opinions, and outright laughing/ridicule will be accepted. :D

 Being a small case and 221 I had build I used 1/14 barrel twist 24" long for the 50gr bullet bullets and it was one of my varmint rifles.

I pretty much stay with one or two bullets for most of my builds varmint,hunting,target rifles so not much help on the subject "widest range of bullets".  What I do who's ever barrel your going to use give them a call I'd be little bit more specific like 40gr to 70gr bullets and sure you get  right answer.
