Some of you may remember I had some issues with OAL with my rounds initially, but I got all that sorted out. I finally made some rounds, and had some fairly bad results. I was using 175 grain round nose Hornady Interlock in 7mm Remington Magnum, with new Hornady Brass, CCI large rifle primers, and Reloder 22 powder. Per the load sheet I was at the minimum charge for this setup. I was getting a noticeable delay between the firing pin hitting the primer and the bullet discharging, no more than half a second. Every round fired with the exception of one, total dud. So it seems I have done something incorrectly. What would give me this kind of delay? Mishandling of the primer, incorrect primer, too little powder, incorrect powder, too much bullet in the casing to achieve OAL (I ended up with a OAL of 3.215), not enough room between the lands and the bullet? I sincerely appreciate all your thoughts and recommendations! I have a feeling after doing a little reading that I might need to bump up the grains of powder and possibly switch to a magnum primer. I tried four rounds of factory ammo (Speer), in the 150 grain range and it fired with no delay, and noticeably more kickback, I highly doubt there is a problem with the rifle.
