The Hodgdon site says to use large rifle magnum primers, my Lyman book says just large rifle
for the same powder? Thoughts?

Also... The Hodgdon site lists a load for titegroup but somewhere I read horror stories about
using TG in the 500. Anybody use it?

Im using H110, 350gr bullet,
 
Having used both Fed LR and LRM have to say I can't tell the difference.

TG 16.5gr is good for practise shoots. Kinda snappy due to TG being a fast burning powder.
H110 and Lil'Gun in the 40-42gr range with 350gr XTP is 44mag on steroids. Great for recoil junkies.
 
I've used both as well, though they were Winchester brand not Federal. Never had an issue with the LR when I used them though I prefer the magnum primers .. for no real reason other than I look at the amount of powder in one of those loads and figure hotter must be better.
 
"hotter must be better" was what I told the Sales guy at Italian sporting goods for why I wanted magnum primers for my 500. He gave me the look replying your want the 500 to be hotter.
 
i bought a case of large rifle magnum primers back when the primer shortage was around because large rifle wasn't available so it's all i've been using for my 500. i would still go with large rifle magnum simply for the fact that it's not going to hurt using them over large rifle even if the load data calls for it. with that said use what ever ones you can get and it will work just fine.

as far as tight group is concerned i would rather save it for my other guns and because i'm slightly concerned about the stories as well. i have powder options so why bother even if the risk is small.

For a 350gr bullet i use 40gr of h110, i've tried 43gr but don't bother going that high because i don't notice any difference recoil wise or accuracy wise.
 
H110 is a great powder for 500S&W if you want full power loads. It's a powder which is rather tough to get to burn well. So Magnum primers are often suggested as being better because the hotter burn and slightly higher pressure from the Magnum primer gets the H110 burning better and more completely.

The test would be in trying some of each and run them over a chrono. Either will work but I'm thinking that it's likely that the Magnum primers will produce more consistent muzzle velocities.

Large rifle is being suggested by some current reloading data because the pressure from the H110 tends to really mushroom pistol Magnum primers. When I shot some 500 for a couple of years from a TC Encore I only used Magnum pistol primers. But the cups were pretty much form fitted to the primer pockets and flush with the rear face of the casing as well as having really sharply defined firing pin divots. I never saw any burst primers or flow back into the firing pin hole though. And since it was a single shot rifle I lived with these results. But technically most folks would consider this extreme a result to be signs of over pressure.

when i started loading for my 500 i used new winchester brass meant for large pistol primers and after 50 -100 rounds my firing pin was toast. i drilled them to large rifle size and the issues are gone. they were hot loads of h110.
 
To switch from larger pistol to large rifle the pockets need to be deeper, the best way to do this is with a large rifle primer pocket uniformer, it will cut them square to the base of the brass and to the proper depth which is 0.008" to 0.009" deeper.

Exactly what Silverback said, I couldn't think of what the tool was called so I just said drilled out. I used a Lyman large rifle primer pocket uniformer.
 
Where did you ever come up with H110 or Win 296 doesn't need magnum primers? They are recommended with all ball powders and I use them in everything except cast loads .I use Win 296 and mag primers in my T-33 pistol......... Harold
 
When I was into the 500 loading the Starline brass I got at the time was set up for magnum pistol primers. The next batch that came in was listed on the box for use with large rifle. That was about 7 or 8 years back.

When I loaded mine I went on the recommendation of a long time reloader that had done a lot of 500 loading. He had tried both and found that while large pistol worked that the accuracy consistency was better with the Magnum primers. H110 apparently being a tougher powder to light off. Once it's going though it's fine. But the better accuracy apparently came from the more consistent starting from the Magnums.
