I went and bought some stuff today - H110 for the .44, Titegroup for all 3, and BlueDot (they were out of Longshot) for my .40 and .45 - they were out of small pistol primers, but i got a few thousand large pistol primers from winchester. they didn't have magnum or normal, they were all just magnum/normal. like on the box it says use them for both. i'm sure everyone deals with this all the time, but since it was my first time buying the stuff, it really threw me for a curve. do i need to get some cci large pistol primers to keep chamber pressures down? or will these work ok? i thought winchester was supposed to be good, but i also thought there was a difference between magnum and regular primers....maybe i'm rambling. anyhow, can someone explain this to me and how its going to effect/affect my loading? Thanks!
