.223 1 in 7 twist ammo suggestions?
 

I was told that with a 1 in 7 barrel I should not shoot 55 grain bullets and that i should use something more like a 60 or like the 62 grain bullets i am currently sighted in for.

I dont know much about the whole ballistic things but should I be shooting a heavier or lighter bullet?

THANKS!

1 in 7 , I would be shooting >62gr, maybe try 75gr.

what exactly does 1 in 7 mean?

and what would happen if i was to use a 55 grain?

Krieger barrels recommends a 1in8 twist for the 75 grain bullet. The 1in7 is for bullets that are 75 grain and higher. 1in9 or slower is good for 55's. Tom.

bummer....so what will happen if i use a 55 grain nosler BT......just bad accuracy?....or worse?

Ain't gonna hurt! I shoot 55's in my 1/7 barrel,just the 1/7 handles heavy bullets better than 1/9 to keep them from keyholing.Just don't try to push them too hard o the lite slugs.

just not ideal spin for the bullet length. 1 in 7 is fast. I myself would pick 1 in 9 or so. You can get great stabilization for 52gr, 55gr, or 62gr. 75gr may be pushing it.

ok....because i guess the "nato" rouns i have are 62 grains and they were grouping fine but all the bullets i want are 55 grain.

Will it hurt the gun to shoot a 55 grain bullet? Will it affect my accuracy and by how much?

Thanks guys....i knows i always have a lot of questions!

As with any Firearm , trying different ammo manufacturer's and bullet weights is a fine way of seeing what the Firearm/shooter likes ordislikes. Try them, see ifyou like the waythey perform.Try diff.brands with the same that weight bullet to see how they do.
