Ok folks need a little help please!  Getting ready to order up a barrel for my T/C G2 in 222rem. (I like the performance of this round). The barrel will be either 14 or 15" long and I am not sure what would be a better twist rate.  I will be shooting a 40 grn bullet for the most, exclusively. (fits between the 32 in the 22mag and the 52/55 in 22-250) From reading, I have seen that a recommended twist "UP TO" 63grn is 1:12 and "UP TO" 55grn is 1:14. I have also seen a slower twist for 4100fps of 1:15 and over 4300fps of 1:16. I know there is no way I will be even close to the 4100 to 4300fps but will I need a slower twist for the 40grn pill?

Berger Bullets recommends a minimum twist of 15" for their 40 grain bullets. The Hornady, Sierra, and Nosler 40 grain bullets with plastic points are a little longer and probably require just a little faster twist. The Berger website has minimum twist rates listed for each bullet size, might help you get a handle on the subject. http://www.bergerbullets.com/catalog.htm | |||
