thankyou!

[lotech]

In a Ruger #3 (22" barrel, I think), I get 1420 fps with 35 grains Reloder 7 and Lyman #457193 plainbase flatnose, 420 grains wheelweight alloy.

thanks again guys , I think I have decided to go with imr4198, it takes 30grs to launch a 405gr boolit to 1370ish, and everything has a 4198 load listed. good day to everyone

You really need to get yourself a Lyman Cast Bullet Handbook.

[Oklahoma Rebel]

do they have a lot more load info, and also do they have more info on casting,cast loads, etc.?

I stopped in Barnes and Noble the other day, and while browsing around I came across the Hodgdon 2016 Annual Manual. If you can find Varget or H4895, it has loads exactly in the velocity range you're looking for. The max load of H4198 gets close to, but not quite as fast as you're looking for.
