My favorite "bunny-buster" load: From Speer #11 manual: 41 gr. IMR 4895 and a 125gr. JHP. (min load: 39 gr. max load 43 gr.) - 2150fps though.

I can't really give you any firm data, but I might be able to help suggest a bit. RCBS lists a reduced load of 10 gr. Unique under a 158gr. SWC as giving 1389 fps from a 20" bbl. I would think that around 10-12gr of unique under a JHP should work and would be a decent starting load. RCBS doesn't list any filler as being necessary with this load.

Lyman, by comparison on lead loads shows a 200gr load over 12gr of Unique, so 12gr. isn't going to be of any real pressure consequence.

Best of luck to you though: keep us posted!
