    Should I change primers?

    I've noticed the regular large rifle primers really getting hammered in my sporterized swede 50 cal rolling block rifles. I'm pretty sure it is the protrusion length and possibly the shape of the firing pin. Also it might be that the original primers that were used in these old military rolling blocks had a very different type of metal and a thicker/harder material. I haven't had any pierced primers yet, but I would like very much not to have one in the future either. I have been thinking of trying some of the CCI #34 primers I have that I use in the sks ammo. Anyone else come across this type of issue, and if so what did you do?

    If the primers aren't getting pierced, I wouldn't be too concerned. My Trapdoor puts a real divot in primers, no problems.
    The solid soft lead bullet is undoubtably the best and most satisfactory expanding bullet that has ever been designed. It invariably mushrooms perfectly, and never breaks up. With the metal base that is essential for velocities of 2000 f.s. and upwards to protect the naked base, these metal-based soft lead bullets are splendid.

    Forget everything you know about loading jacketed bullets. This is a whole new ball game!

    waksupi,
    I'll have to see if I still have any cases that I have not already de primed and take a image of it to post. It is a real as you say divot.
