I have found limited stocks of 62gr-68gr 223 ammo. The rifle I am shooting has a 1:7 twist rate.
For those that shoot different barrels what weight bullets are better for the different twist rates?

This one has the 20" barrel marked 5.56 nato 1/7.
Some of tha ammo available cheap includes 50gr and 40gr. These make for larger groups of cut paper.

The longer the bullet the faster the twist rate you need. 1/7 is perfect for SS109 or heavier bullets.
