Is there a metallurgic / ballastic reason why no cast bullet <370grn for SW 500?

[BrokenWheel]

Just looking around for a lighter bullet for the SW500, since the lead cast ones are usually cheaper. But I cant seem to find any that are less than 370 grains. The ones I find are lighter are jacketed and seem to be more expensive than just plain lead cast. I was wondering if there is a reason for this...

When they are too light they go too fast for exposed lead?

well, a round ball of pure lead would be about 190 grains, so I'm not sure. Ther's nothing that says you have to load a cartridge to drive a bullet to the capability of the cartridge, and I can see why it would be nice to be able to shoot your behomoth wih something a little more tame from time to time.

Have you tried contacting any bullet casters? They are usually pretty small companies.

The lighter the lead bullet, the smaller the bearing surface of the bullet. Less bearing surface less accuracy. The light jacketed bullet grips/takes/holds the rifling better, no skidding like lead. Total guess on my part.

We have the 400 grain RNFP flat-base for the .500. It's the "Crusher #1." Very pleasant to shoot, assuming that you are a mastodon.

Just to show support for your great products, MB, I did go check to see what you offered, but I didn't post the "Crusher" because he said he was looking for less than 370 gr.
