Twist Rates and Bullet Weights

[Clark Howard]

Rules are rules, but I would try a new bullet to check actual performance. Your combination may work fine---or not. Then you will know. Regards, Clark

I can not get 69 gr. to perform in my 1 in 9 twist 20" heavy barrel. I won't even try 77's

IMHO the 69 gr is a bit heavy for a 1/9 twist. I shoot 62 or 65 gr in my 1/9 guns. In my 1/7 twist I shoot 69 gr mostly.

I have 7 twist, 8 twist, 9 twist barrels on different 5.56 and .223 rifles. You just have work up some loads and test them in your gun to find out what will shoot.

The longer the bullet the more twist required to stabilize the bullet. Weight does not affect stbility, but length does.
