I took my first batch of reloads to the range and it did not go well, nothing but hang fires. I am shooting 7.7x58 Jap PPU brass (brand new)/150 gr PPU soft point with 41g of BL-C (2) using CCI #200 large rifle primers. I fired 5 rounds, 4 were 1 second hang fires, the last never fired but did have enough oompf to push the bullet into the rifling. I feel the primer is the issue and not the correct choice, what are your thoughts and recommendations?
Going forward I have two pounds of IMR 4895 coming.
