Im looking for a load for a 430 gr cast at 900-950fps to plink around with. Only powders i have are 296/h110, which are not able to down load, AA#9 not sure about that as i have found it to be a bit picky and some 2400. I found some .50 special loads with 19gr of 2400 at 950. would that be safe in the GNR which is .1 longer? im getting 1300 with 29 gr of 296 but its not something i want to shoot a lot of. would i be ok with the 50 special load?

Shot a few saturday with 19 grains of 2400. Was 630-650 across the screens. No recoil at all. Was wanting more in the 950 fps range. I'm thinking 21-22 grains should do it. I plan on getting some HS-6 whenever I can find it for some reduced playing loads.

No 500GNR experience but that's a Trail Boss proposition if you ask me. Fill to base of bullet and seat without compression.
BTW I agree that 2400 is the best for reduced loads considering what you are dealing with.

I too would suggest HS-6...Use in my 475 and 500 Linebaughs, 15 & 16 gr. with 420 gr. bullet, for around 1015 and 1025 fps. mild recoil. Will shoot 46" of wet pack. With a LBT 420 grainer, or both shoulders of a Bison. FWIW

Don't know the .500 GNR, nor have I loaded for any .50 revolver. Hercules 2400 and Alliant 2400 may prove unsuitable for your desired 950 fps load, if there is a lot of airspace. 2400 remains a great powder for accuracy below 296/H110. And while 2400 tolerates some air space----generally better than 296/H110----propellants in the medium pistol range work fine with air. I would add Accurate #7 as a potential candidate in the HS-6 position. Avoid at all hazards a double charge of medium powder.

Just worked up some light loads with Unique for the 500 JRH. Posted on Single Actions for my BFR. Something similar should work fine for the GNR.

Right now all I have is 2400. But I'm having a problem now with squibs. 6 out of 10 rounds with 28.5 grs of 296 didn't go off right. Bullet would either be at the end of the barrel or would be a few feet in front on the ground. Primer was pushed back and the gun was full of yellow powder. I pulled all the rounds I had loaded none were under loaded. I have been using fed 155 primers but switched to fed 150 as I ran out of 155's. Not sure what is happening I've never had this happen before. The primer is the only thing I have changed. Any ideas? I got some more 155's but I don't know if that was the problem. Not all the rounds did that.

Hate to bump an old thread, but I'd like to hear some thoughts on the OP's last post, regarding some bad loads.
Thanks for any input.

After talking with Gary and some playing around we ultimately decided that it was a combination of the primers and the mix of my alloy. I had cast some pretty soft as I was having trouble getting them sized right. Went back to casting them harder and switched to Winchester large pistol primers haven't had and trouble since. Still have problems with them not sizing right but I have another mold on the way. The lee mold is fine for a $20 mold but it is kinda picky about how you cast it.
