Magnum Primers

[G38xOC]

one calguns member was nice enough to give me box of wolf small magnum primers .

I usually use regulator primers when I reload .. but my question is .. do I need to bump down grain or two if I were to use magnum type ?

Whenever I use magnum primers in 9mm, I decrease the load down by 0.1grains of powder. I use HP-38.

Magnum primers are usually thicker so you don't get pierced primers from the higher magnum pressures. I haven't seen any evidence that they dangerously raise presures. The powder burn rate isn't going to change.
