I'm fairly new to reloading. I have reloaded 9mm, 45 ACP, and 44 magnum with no issues. I'm moving up to the 500 S&W magnum next. I have a question about the brass however. I bought my brass "once fired", there are several different headstamps. Some say R (large rifle) and some don't. I'm assuming the ones that don't say R take large pistol primers? Attached is a picture of the headstamps I have received. I'll be reloading the 500's with Lil Gun (any other suggestions on powder would be great too). Am I correct in thinking that only the headstamps with R or LR take large rifle primers and the others take large pistol primers or large pistol magnum primers? Any help would be great! thank you!

1-Reload according to manual. My manual says large rifle magnum, so that's what I would use, no matter what's on the brass. Don't use non-magnum primers with magnum powders or vice-versa, it'll mostly suck.
2-Only difference between rifle and pistol primers is supposed to be cup rigidity, so the brass wouldn't determine which primers to use (unless it's the size large/small such as for 45acp).
3-I would try H100/W296 for powder.
 
I reload 460 magnum and 454 Casull with Hodgdon H110 but it's kind of tricky on the crimp and load. What I mean is I tried smaller loads with the Casulls but needed a heavy crimp otherwise the primer would fire but the powder would not ignite giving you a nice squib to get out of your barrel. What seems to work for both is a load as close to the seated bullet as you can and a normal crimp. (pic of a crimp for 357 magnum and a few Casull. Crimp is the same for 460)
Once you get used to that powder it's all good but you might have a few squibs at first problems will all be crimp or load

I also reload 9mm .45 ACP and a few 38 special but the large 45's were another ball game

Thank you. I was thinking about using H110 or Winchester 296 as well. Do you use a factory crimp die or the seating die to crimp the 454? I have the 3 die sets for my 44 magnum and the 500. I had a problem today at the range with the 44's. The crimp wasn't tight enough and the 6th round would extend past the cylinder. I had to take it out and reseat it before shooting it. They weren't loaded with H110 though. I'm taking baby steps with the 500.

I use the seating die to crimp the 500.
 
I wouldn't use max loads with pistol primers in the 500, that's why they have changed it to rifle primers. I bought a bag of winchester brass for my 500 and it used large pistol primers. after wrecking a firing pin using near max loads of h110 with large mag pistol primers i picked up a large rifle primer pocket uniform tool to change them to rifle primers. I only use them for light target loads now though.

As for powders i've tried alot for my 500 mag; H110/W296, lil'gun, AA1680 are good for full house loads. imr 4227, imr 4759, imr 4198, AA5744, longshot are good for midrange and trailboss for very light loads.

For jacketed bullets i seat and crimp in one step with my lee dies, for cast i seat in one step then crimp in another, both steps using my lee dies.

Lighter bullets like the ones your using don't seem to need as heavy of a crimp but with my 700gr loads i need a very heavy crimp. I've had the 5th round come out enough to lock up the cylinder.

2-Only difference between rifle and pistol primers is supposed to be cup rigidity, so the brass wouldn't determine which primers to use (unless it's the size large/small such as for 45acp).

large rifle primers are larger/taller (height wise) then large pistol primers.

Awesome information! Thank you!! I've separated the brass. The ones that require large pistol primers will be saved for lighter loads. Should I use large pistol magnum primers or regular large pistol primers? I have thousands of regular large pistol primers. The majority of the brass has large rifle primer pockets. If you have any recipes to share for a good mid load I'd love to have it. The only powder I have right now is CFE Pistol so I'll need to buy powder for my 500 regardless. Thanks is again!

should be fine with large pistol primers but i just use magnum because they were always available. I'm planning on making a thread in the new recipe section for the 500 mag when i get some free time. Just keep an eye on the primers for pressure signs and you should be fine.

I'll keep an eye out for your post. Thank you. I will give it a try with the large pistol primers and large rifle primers. I'll make 20 at a time and see how it goes at the range. I look forward to seeing your recipe!

I would use long wooden fireplace matches to light off your 500 S&W and go easy on the charcoal lighter fluid. you could burn all the hair off your hand and arm. :evil:

I'm using a factory roll crimp, the seating/crimp die didn't do so well (which is why I had squibs. seating die does work for the 357 though) if I went further I was squashing the brass on 454's. Lucky for me the 454 crimp die also works with the 460 magnum.
RCBS does have a roll crimp seater die for the 500

Crimping counts for a lot on these high power rounds

Excellent!! Thank you!!! Any suggestions for mid power loads to throw down range? I'm using 350 grain Hornady and 350 grain Berry's. I appreciate all your input.

i am using 440Gr cast with a GC H110 35Gr
700Gr cast with GC H110 28Gr.

will watch for the recipe page, didn't even know that was here... have some other bullet options to cast in a 4 cavity noe mold, 450,500,550,600 and another which is 490 and a NOE 375 Grain .502 Spire Point on the way. going to be doing some casting soon...
