Primer swapping

[mdi]

Couldn't find a better sub forum to post this so here goes; With the many new reloaders on forums dealing with component shortages, primer use has been a popular topic ("I couldn't find XXX primers, so can I use YYY instead?"). I found this video on another forum and so far, it's the best, most informative bit of info on primer swapping I've seen. Real life pressure testing. Real life velocity testing. Very well put together, professional quality info-video. https://www.youtube.com/watch?v=NGVRGsoOr6k&feature=youtu.be&ab_channel=SuperVel

I tried SP and SPM with the identical load and boolits shooting off a rest and got totally different results on paper :(

Regardless of reports, info posts, any time I change a component, I'll do another load work up...

Very good info.

That was great information !

A few years ago when I was just getting back into handloading, I had an abundance of small rifle primers, but no small pistol. I used the SR primers in 38 Spc and 357 Magnum without any discernable difference.

Excellent video. If that doesn't put the debate to rest, at least amongst those 3 sizes, I don't know what ever will.

Good video I have been doing this for years, with the same results.

I use SRP exclusively for everything requiring SP or SPM primers. No discernable differences yet, but the load development process begins with a SRP from the outset. Because of this, overpressure has never been a concern.
