Who has been experimenting with the different grain weights of the ammo they use in a 9mm P226? What differences have you noticed in your gun's performance between 115, 124, and 147 grain?
Thanks!
Hi - all. Just bought my first AR. A Sig516. 16inch barrel, 1:7 twist.
What is the best grain to use for 50-100yds at the range? Everyday plinking use.
Thx!
