Bullet Moulds for CZ 550 458 Lott and 416 Rigby

[Just Duke]

Sannee Claws might be bringing me two of these rifles to scope up and I'm looking at casting and loading data for both these calibers.
I think I'd like the keep the muzzle velocity around 1300 to 1400 on both of them.
TIA,
Duke

If you can track down a 462560 it would be great in the Lott.

Easy as looking up data for the comparable or close cousins within the older cartridges. To find the cousins of the modern 45 and 40/41 cals get an idea of relative case volume... doesn't have to be within .000001 gr.! Slug the bores on both for idea on what to size the cast to. Most all the the old cartridges have at least some smokeless data available. Pick a bullet design and weight to the liking of the rifles' twist rates. If you want fewer problems look for gas checked bullet designs. Powder? consider 5744 for velocities in your range.

I have excellent luck with my RCBS 416 350 gr. FN design. I load it for my 416 Taylor with either 4320 or 3031 powders. I just got it back from Buckshot making a convertable mold out of it, either a hollow point or back to solid nose.Robert

I might just be interested.

The Lott is great in that you can run from trapdoor to more than you can stand in one rifle ..

If I had to pick one powder for cast or j's from trapdoor to more than you can stand , it would be 3031 ..

PM with your email and I'll send pix of the boolits and moulds if you like ..
