My question is, can I safely use small pistol/magnum primers in standard 9mm?
That question has been asked many times in the last year. The answer is YES provided your not at MAX load. Best to drop back a couple of tents then work back up. Some striker fire pistols have problem setting them off. Just need to test in yours.
In my speer manual there is a passage waning about replacing magnum and regular primers in pistol. They say according to their testing they would see 5,000 psi higher pressure in small case volume round such as 9mm when the primers were switched to mags.
Only striker fired gun I have is the semiauto sten and it punches the heck out of the small rifle primers I use to load my special ludicrous hot sten only 9mm ammo.
Just wanted to play it safe.
I don’t load to max, and I don’t own a chronograph (you would think I would) a friend had one and he recently moved.
Thanks, I enjoyed your day at the range too.
@Cookie223 welcome to the forum. Since your question has been answered I won't extrapolate any farther.
