Bullet Diameter .358 or .359 for RD 180 gr/Lee C-358-180rf?

[MickeyJr]

Hi All,

Finally getting around to casting some RD/Lee bullets for my Marlin 1894C 357 mag rifle. 20+ year old rifle Micro-Groove rifling.
What diameter do you recommend I size the bullets to .358 or .359? Will use Lee push through size die.

Thanks In Advance,
MickeyJr.

When I read your question, I looked at the Lee site. He does not have .359 as a choice in the push through sizes. He does have .358. If I had a choice it would be .359 or .360.

What's the as cast of the bullet?

I had a Marlin 357 rifle with microgroove and it liked the .359" boolit better. It is easy to hone out a Lee sizer with a split dowel, sandpaper, and a drill.

as cast come out at approx. .3585

Shoot them and see how they do. Might be just right.
