Is it good to shoot 62 grain out of a 1x9 twist?
« on: February 11, 2010, 02:03:36 AM »
I've heard that it's not a good idea to shoot 62 grain out of a 1x9 twist, how truthful is this?

Lies all lies. A 1 in 9 twist rate should stabilize a 50 to 70 grain bullet give or take. At least that is what I remember from when I was looking in to it.
Gun control means i can hit my target!

Yeah its BS, it works well on 62 gr, I average slightly better groups on milpsec ammo using 62gr as opposed to 55gr.
Actually I have a couple 1/9 twist barrels that love Privi partisan 69gr match.

These type of questions come up fairly often when it comes to the .223 because virtually no other common caliber has the wide variation in twist rates and suitable bullets for those rates as the .223 Remington/5.56 NATO.

We had this discussion in the "Reloading" forum a while back and I tried to come up with some answers and explanations.
That twist rate thread has been added to the RIFLE FAQ AND TUTORIAL LIST sticky at the top of this forum as ".223 Twist Rate & Suitable Bullets".
www.sksboards.com/smf/index.php?topic=58230.0 is the direct link.
