What is the lowest bullet weight that I could use in a 1:7 barrel?

As low as you want to go.

You will not get enough speed out of an AR to "over rpm" most bullets.

varmint bullets with very thin jackets at high velocity may not stay together with the fast twist barrel.  I think lighter bullets with normal jackets are fine.

Would you loose accuracy?

you wont have accuracy if the bullet doesnt make it to the target and if it does it will pepper it.



i have shot 55gr with no problems

That's good to know. I just finished a build with one of Denny's recon barrels and haven't shot it yet, but I was wondering if I was gonna be stuck using the heavier bullets.
