S&W 500 Mag Loads - Need some help.

[EddieCoyle]

I bought some 460gr gas-checked cast lead bullets for my 4" S&W 500. I plan to load them over H110. I've found the following published loads, which I believe to be significantly under maximum:

370 Cast - 42 gr H110
440 Cast - 39 gr H110

I'm thinking that I should start with 37 gr and work up.

Does anyone have experience with this caliber/bullet weight? Clark? Anyone?

Thanks.

My Hodgdon manual shows:

370 gr. max 47.0 of h110
440 gr. max 38.0 of h110

I have been looking for some LGC bullets in the 450-460 gr. range. Where did you purchase them and do they have a website?

Thanks in advance...

I found a load using Titegroup instead of H110. Here's the load:

Bullet: 460 Hard Cast Lead Gas-checked RNFP
Powder: 14 grains of Titegroup
Brass: Starline
Primer: CCI Large Rifle

Here were the chrono results of the 20 test rounds:

Avg: 1044 fps
High: 1060
Low: 1029
Std Dev: 8!

These loads were very accurate (for me) all 20 were in a 7" group fired offhand at 40 yards. The gun was a S&W 500 w/4" barrel.
