500 S&W

[50 Shooter]

Has anyone loaded some of the 700 gr bullets from Matt's? Just placed an order for a box of those and some 390 gr spire point bullets. He said he would send some load info using H110.

Anyone have any other load recipes? TIA

I talked to Matt, he said that his orders are running about a month out. Check out his selection of 500 bullets that he has. My next order is going to be some 600 gr and 440 gr. bullets.

I've not loaded 700 grains in a 500 S&W, but I've done 740 grains in a 460 S&W. I like IMR4198 for powder for such a heavy. If you can find load data for a similar cartridge, like a 50-70, 50-90, 50-110, you can multiply the starting load charge weight by however much smaller the waterweight of the 500S&W is and go from there. Whatever the charge, the bullet gets seated right down on top of the powder for 95-100% case fill. That's your starting load.

FYI (this doesn't help you), a 460S&W case is 75% of a 45/70 case. The only other rule I found is don't go TOO slow in powder. In my case, 4198 is perfect (albeit too slow, just not too slow to misfire or leave powder in the barrel), 4895 is way way too slow.

I'm sure H110 will work OK for the heavy bullet. If the recoil is too much or you see other issues in your gun, you can back down, you just have to keep seating the bullet down for 100% case fill and you are golden. Personally, I never loaded H110 for anything heavier than 550 grains in the 460. But I'm sure it could be done. It just wasn't needed, 4198 results in far less flash and shock. Recoil impulse is slower, it's just so much easier to take compared to H110.

I've loaded the 700s with 27grains lil gun and 25grains h110, mag rifle primers. They are definitely stout loads.
A nice "light" (comfortable to shoot more than 5 round) load is 10 grains of unique with the 450 Keith or any of the lighter bullets he sells

Thanks, I saw some of the loads while looking around, guess I'll need some more H110, Unique, 2400 and LiL Gun. I read John Ross' page, some good info on the 500 S&W.

Just have to wait until the bullets come in, until then I guess I'll be looking for powder. That and Matt said to get the Lee crimp die as others tend to mess up the spire point on the 390gr bullets.

I have never used the spire points. I have the rcbs carbide dies and bought an extra roll crimp die to crimp separately. They come with 2 seating stems, a tapered one which would probably work with the spire points and rounded ones, and a flat one which has a lip that I filed off to fit the 700s without leaving a ring mark.
