1. Check with your F&G. Some states require 25 cal & up.
2. Check the twist rate of your rifle. You need 1:9 or 1:7 for heavy bullets.
3. Accurate Arms data for 2520 powder (best choice for these bullets):
Barrel: 24 • Twist 1-7 or 1-9
2520 65 SIE SBT 24.9 2,982 27.6 3,239 61,238 2.210
2520 70 BAR TSX 23.9 2,826 26.6 3,103 61,552 2.260 <--Copper bullet
Speer also makes a 70 gr lead SP
I shoot the Barnes 70 gr copper bullet through a 1:9 savage. It shoots fine.
