RE: .223 1 in 7 twist ammo suggestions?
The 1:7 twist is for longer heavier bullets ie; 69gr on up to the 80gr. The 55gr bullets will shoot from the 1:7 without doing any damage but your accuracy could suffer. I had a hard time with accuracy with the lighter bullets out past 200yds so I use the 69gr Sierra match king andthe problemwas solved. Thematch king bullets are a hollow point with a thin jacket andexplode when entering an animal. I thinkyou would like the results and the accuracy more than with the 55gr bullets.

since no one answered your ? about what does 1 in 7 mean, it means that there is one twist of the rifeling every 7 inches. thats a fast twist. they can go as slow as 1 in 14, thats 1 twist every 14 inches. the faster the twist the heavier the bullet that you can shoot.

RE: is the deal still on babe!
Agree with Head, you need to consider a 75 grain bullet.Typical 223 is 1 in 12. I have a friend that just had a 22-243 built with a 1 in 8 twist. He was determined to try his 55 grains based off his 22-250 load before he had the gun rebuilt. Found out the gun make was right when he recommended the 90 grain bergers. He couldn't come close in his groupings with the lighter bullets to the accuracy he is getting out of the 90 bergers.
