Hello,
I just got a good deal on a few thousand win small pistol mag primers and would like to use them in 9mm and 40sw along with my 357 mag. I usually use WSF powder in both - 9mm load is 115 fmj with 5.5 grs and wsp. 40sw load is 6.3 grs with a 165 gr xtreme tc and a wsp. How much should I adjust for the use of a magnum primer? Thank you for your input.
