MP 502-385 HP load data for 500 S&W Special?

[singleaction]

I just placed an order today for a couple of the plain base versions, for use in a 500 S&W Special. This one is listed as weighing 400 grains without the hollow point, and 383 grains with. I’m most interested in data for the HP version, but either or both would be appreciated. Thanks

They would both use the same data.

Charge amount has to do with how much room the bullet takes up in the case. HP vs solid doesn’t change this.

Thanks. I figured bullet weight made some difference, but I reckon 3.25% weight difference is to insignificant, especially at the low velocities I will be working with.

It does but the amount of bullet seated is the biggest determinant…

The hollow point is likely to hit to a different point than the solid at 50 yards plus due to the weight difference with the same load. The other detail I have found with big bore MIHA bullets is not all of the nose configurations are as accurate as the others. I found with the 478460 475 Linebaugh mold the large hollowpoint is way more accurate in my gun than the solid is.

You will just have to test and sort out what you and your gun like.

Seems all the 640 designs run well. I've never cast HP's with mine for the 475 and I've had fine accuracy out to 100 yards from my guns. So much so that I generally only run those guns when I'm alone at the range. As a quiet kid I really don't care for other shooters coming up oogling my gear and telling me what a great shot I am. I'm always end up trying to tell them, man it ain't me. I just point the bangy end, pull the little flipper and voila, teeny groups!!

Thanks for all the comments and advice. Much appreciated!
