I've had good results with a number of primers. I keep a lot of brands on hand for testing.  In my .45-110's WLR primers work well with my paper patch loads, Federal LR Magnum are what I use in my .45-90, and I use Fed LR Match, CCI BR2s, and Fed LR in my .45-70s.

The one thing that sees to be true is that a primer change can make a much bigger difference in group size than going up or down by a couple of grains of BP. You just have to try them and see.

The one trend I've picked out is that the lighter the powder charge, the more my loads perform with a magnum primer.   

I should add that all of my loads are for various .45 cal rifles.  I have an original Winchester 1885 schuetzen rifle in .32-40 that I've yet to work up an accurate load for.   

I've played briefly with pistol primers, but not enough yet.

Over primer wads do seem to improve accuracy in some of my loads.

Fashion changes when I first started with single shots everyone told me to use magnum primers. Now they are using regular primers and some are using a newspaper wad under the primer to muffle it more. As black is pretty easy to ignite it would seem to me that the issue is more finding a powder that will give you the best cleanest burn than how to set it off.

I'm another pistol primer advocate. I use only Rem 1 1/2 & 2 1/2 for BP and also with 4759. I've not used the tisue paper over the primer hole but, it sounds like a good idea (to keep "fines" out) and I will use it this coming spring.

Jack---If you think it's dangerous, then by all means wear shoes! I think you missed my point.

New member or old It's not smart to point a gun at anything you don't want to shoot.  

Bruce Lee's son blew his brains out on a movie set with a blank.  Experienced shooters don't point and snap without considering were the gun is pointing, You never know what's going to come out of the muzzle.

With that caution taken,  I migrated from Federal 215's Magnum primers when they were in fashon dozen years ago to Remington large Pistol primers in my 45/70 38/55 & 32/40 loads.  When last years primer shortage developed opened up a 1000 215's I put away in the primer shortage 10 years ago and used them in 38/55's with 4759. They did fine.

Still given a choice it's large pistol for me.

Nice illustration of brilliance in primers. Many shooters confuse the softer pistol primers with having a softer brilliance. This is not true pistol primers go off with a lighter blow but the explosion, if you will, is the same as rifle primers.
