This is our first 45/70 Subsonic load. The powder burn is clean and velocities are extremely consistent. This is a very low recoil load that is fun to shoot with or without a suppressor. As with all subsonic loads, ensure your fiream can stabilize the projectile prior to shooting through your can. These have no problems stabilizing with a 1:20 twist rate- the most common found on 45/70 rifles.
