Primers when loading Pyrodex?

[Darto]

With primers hard to find at reasonable primers, is it possible to load 44 colt pistol cartridges using Pyrodex P and regular small pistol primers (non magnum)?

Reason I'm asking you all is I have never loaded black powder or substitutes before. Am longtime Ruger Blackhawk (45 Colt) owner and reloader. And have just always used regular CCI large pistol and Red Dot and have a large stock primers in reserve.

Do I have to go get some magnum primers to load right now?

I've never used a magnum primer with Pyrodex RS or even real black powder. That includes the brass shot shells I have that use large pistol primers.

Alrighty then I'm good to go. whole new world for me here

In my experience it does not matter much which you use. It might give you a grouping issue if you mixed them casually but there is not much difference in performance otherwise. In todays components market I would not care which I was buying.

I have been using Federal magnum primers (large & small) with Goex in 45 Colt, Cowboy 45 Special & 38 Special loads without any problems.

This whole BP thing is either a ford vs chevy or voodoo thing.  Some say magnum primers are the best, others say they are the worst, still others use tissue or news print over the primer to moderate the flash.  Some compress 1/8 inch some .300 the real truth may well be what ever goes boom will work just fine at CAS ranges.  Long range is where the real voodoo kicks in with different powders, different granulations of the same powder, lubes, lube cookies, big lube bullets, blow tubes, wiping or not wiping, case stretching, this 500 grain bullet vs that 500 grain bullet or neither because 485 grains is what you really need etc.  It can make ones head hurt and spin at the same time.

All the above are what makes it both challenging and fun if you share my masochistic tendencies.
