The load I sent for testing is this load, with the exceptions of 2.75” hull and no 1/2” fiber wad. Because of the short hull the fiber wad is not needed for proper stack height. Pressures are approximately 1,000 psi more than the load published in the PP. Bruce Ducksworth believes the increased pressure is due to lack of a fiber wad which apparently reduces pressure. Velocity is the same.

Can you give more detail on the "Hi-Cap wad? I only know of Gualandi and Rem SP8 wads in plastic.
