I just bought a Freedom Arms .475 Linebaugh. Accompanying the revolver were two buckets of bullets. The Seller could not identify either bullet. Seller said he got the plain-base cast bullets from a friend in Billings, Montana.
My scale has gone heels down. I cannot furnish bullet weights. Here are their physical dimensions as best I can. Jacketed bullet on left has a concave base that I do not show.
1. Overall length of jacketed bullet is about .928 inch; cast bullet is about .933 inch.
2. O.D. of both bullets is about .475 inch.
3. Meplat of jacketed bullet is about .327 inch; cast bullet is about .395 inch.
4. Length from crimp to nose is about .355 inch for both bullets.

After comparing online graphics with bullet, I believe the cast bullet is not Lee .475/400 grain, or RCBS .476/400/SWC.
The cast bullet is impressive to examine. I do not know whether it will function satisfactorily and accurately in my Model 83, or .480 Ruger SRH. I am uncertain the lubrication grooves are sufficient for their job -- I understand, for example, Lee's 475/400 plain-base bullet has lubrication grooves that are right on the edge of being inadequate.

One last thing, What is the best currently manufactured balance beam reloading scale? The best is always less expensive in the long run.
