LRP vs LRPM

[BriarPatch99]

If you spend some time over a chronograph... you will find Magnum LR will add about 25 fps to your average .30/06 "style" cartridge and according to folks with pressure measuring equipment... about 1000/1500 lbs pressure (psi)...

So if you live on the edge of your cartridge then be careful swapping ...otherwise you will notice very little difference...

I have not done enough testing to say with pistol primers... but I would be willing to say ...if you are on the edge of pressure limits in a pistol cartridge... be careful swapping... the smaller the cartridge brass capacity... the more the difference will be...

If you are loading middle road stuff ...I don't think you will be able to see the difference..

@rosewood picked up 1K of these this morning with a couple buckets of .45ACP brass, bullets and dies.

Burned through a box of those a couple of years back. Were flawless.
