Does anyone else here use Magnum primers...

Member Posts: 168,427 ✭
for all large rifle primer applications? I pretty much use Federal 215's across the board. My thoughts are that they should give a better powder burn, but I was reading someone else's post about primers this morning and it kind of got me wondering if this might explain why my son's '06 is not grouping so well.?.? I still need to try some other powders and possibly play around with the seating depth but the primer post made me wonder... Thanks!

Cases holding less than about 60 grains of water (the most common measurement method) probably don't need magnum primers ever.
Extruded powders don't usually need more than standard primers except with very large charges - related to case volume again.
Shooting in temperatures above freezing doesn't require more than standard primers, unless cases are large, charges are large or spherical powders are being used.
The .30-06 holds about 55 grains of water. With extruded powder, and loads intended for moderate temperature shooting, standard primers will almost certainly be a better choice. That's what it was designed to use.
"More" is not always better. Generally speaking, the mildest primer that will acceptably ignite the powder will give the best accuracy. Selecting that primer depends on case volume, the particular powder, and the temperature the round will be fired at.

I reckon I'll try some 210's...
I prefer Winchester STANDARD primers in my 30-06 class rifle loads because the shoot better and more consistently. I do use SRM primers in the 6 and 22BR with Varget
Yes I use them, but just for the magnum applications. [:)]
