in need of reloading data for a sw500 nwfl

[CHEVELLE427]

i just picked up a sw 500 in 4" and i reload so of course im going to reload for this as well , i am finding limited info on this but have found some good sites , BUT i just found one that talks about cases pre 03 took pistol cases and now are marked with lr for rifle cases /
my question is i have also scrounged up some 500 brass and there a mix some with an R some without .
i know the rifle case the primer pocket is a bit deeper , the question is do i have to use a mix of primers , can i still use my cci 350 in all the cases or do i need to just use rifle in the ones marked so .

also anyone have loads they would like to share please do so . for now im setting on a lot of ols 50 ae projectiles and would like to use them up first there raniner 335

thanks

Early cases for the .500 mag used large pistol primers. However, there were problems with the primers piercing with hot loads. Starline and others who make brass for the .500 switched to large rifle primers (and pockets) and marked all cases with an "R" to indicate the change.

You have a couple choices:

1. Use the old cases for light loads (12 grains Trail Boss or such) that have low pressures
and won't pierce the primers.
2. Buy a Lymon large rifle primer pocket reamer, and take about .007 inch of brass out of the bottom of the primer pockets of the old cases. Other than primer pocket depth, there is no difference between the old and new cases.

I've only got two loads that I shoot in mine:
400 grain lead from Missouri Bullet Manufacturing over about 12 grains of Trail Boss
300 grain Hornady FTX (also available occasionally from Midway as blemished for about 2/3 the price) over 47 grains 'Lil Gun.

The Hornady data is much hotter than in any of my other manuals, but 47 is still below their listed max. It shoots fine and extracts easily in 2 different S&W revolvers.

If shooting max loads you'll want a bullet with a good crimp groove to prevent setback.
