201gr SWC are 216gr

[RSVP2RIP]

I'm using 10:1 alloy in the RCBS 201gr SWC mould and the finished weight is 216.4-217.0 grains. I know that 10:1 is heavier than #2 alloy, but should I just extrapolate load data from 200grain and 230grain cast bullet loads? I have a can of Bullseye sitting here doing nothing and thought that 4.5grains would be a good starting point from what I've come up with. Maybe 5.5gr as a top end. What do you think?

Gun, caliber?

If you're talking about .45 acp, then you're in the ballpark with your proposed loads. The mold will probably drop a bullet closer to the designed weight with linotype, or an alloy similar to Lyman #2.

Hope this helps.

Yeah probably should have said 45acp. Shooting a DW Valor.
