Default small pistol magnum primers in non magnum rounds

I have some CCI small pistol magnum primers. I do not load magnum rounds. Can these be used in 9mm or 38 Super rounds ? if so, do you have to adjust the loads ? Thanks.

Reduce your powder charge by .2 grains.

Unless you're past max book, just load em. They'll work fine.

IPSC shooters used to run magnum pistol primers in .38 usper and 9mm Major to help deal with the higher pressure levels. Some competitors used small rifle primers. Like the other OP said, unless your load is over the max, not an issue.

load them up. That is all that I use. I do not even buy reg primers anymore. I have never had any problems even with max loads

Yep, given the option I choose magnum primers.

I use them interchangeably in my loads. Since I load on the lighter side I recon I can use all the ignition/pressure help I can get.

I've only recently noticed some loads not fully ejecting and I attribute it to using regular primers with softer loads that I designed originally with MAG primers.

It's so inconsequential unless you are at the far upper limits or the far lower limits.

Default What does your Reloading Manual say?

There once was a short while when I too thought I knew better.

I used mag primers for 38 Special loaded with 2.7 grains of Bullseye and 148 grain hollow base
wadcutter, HBWC, bullet.

Even at the 7 yard line I noticed a bigger pattern. At 25 yards I was blaming the sun angle.
And at 50 yards I held a nice looking 12 gauge double ought buck pattern.

Proper bullet selection for intended target use, some pistol powders perform with better efficiency
under higher or lower ambient temperatures, proper cartridge assembly, are all much greater
factors than primer deviation.

I load my rounds on the low-middle range & I use them interchangeably with no adjustment on the powder charge.

Using mag primers when not called for in the load data can cause some pressure spikes with some powders.

45 colt FOR LARGE FRAME RUGER REVOLVERS OR GUNS OF EQUAL STRENGTH
Wt. Bullet Powder Manufacturer Powder Charge Velocity (FPS)
310 Mt. Baldy Keith cast Ramshot Enforcer 21.0 1352
Remarks: primer: CCI 350; 35,950 psi(50% more pressure)

310 Mt. Baldy Keith cast Ramshot Enforcer 21.0 1238
Remarks: primer: Remington 2 1/2; 23,990 psi(accurate data uses these)

310 Mt. Baldy Keith cast Ramshot Enforcer 21.0 1239
Remarks: primer: Winchester LP; 22,490 psi

310 Mt. Baldy Keith cast Ramshot Enforcer 21.0 1278
Remarks: primer: Federal 155; 27,870 psi


Enforcer and 4100 would be 2 of those, i think Brian pierce also says 2400 is another powder in which mag primers cause wild fluctuations in pressure. The pressure and velocity the load books give you are with what they used, when you substitute something, a different case, primer or bullet(just because it weighs the same doesn't necessarily mean you can use the data) your results could be different. Work your load back up using starting data and a chrono to see the difference.

With rifles, flashover is the concern.

The powder lies flat and too much of the powder all along the case ignites along the top edge of the powder or worse yet the front and back ignite before the middle ignites.


Less of an issue with handguns
