1/8 twist for AR and Bullet Weight question

[FCB1616]

Will shooting a lighter bullet say a 55gr vmax or 55 gr sierra bk be worth even trying in an ar? and what bullet weights would maybe be better if these didnt work?

yep, they will shoot in an 8 twist just fine.

I run 53 through 70 grains in the 8

55grn pills tend to do fine in any "typical" AR twist, whether 1:9", 1:8", or 1:7". Pretty hard to over-stabilize so much that you have a negative consequence.

You'll only get into trouble if you UNDER stabilize a heavy bullet, like a 75grn in a 1:9" 16" barrel.

Yup. Kansas guys is smart.

55gr will shoot decent through 1:7-1:9 twists.

My 1-8" ultra match barrel will shoot 40gr V-maxs into one hole at 100yrds.

American Eagle Varmint tipped 50 grain is best shooting factory round that I have found for my 1:8 twist AR!

I run 55gr NBT in all of my 223's and they shoot very, very, very well. A couple are 1-8 and then there are a couple 1-9.

+1 I also have very good luck with the 55gr Nosler BT in my 1-8 twist.

My 1 in 9 AR loves the 53 grain pills and oddly enough my wife's 1 in 8 AR likes the 40's better so go figure!!!
