Can't find it in my loading notes, but did find a maximum load of 20.5 4198 with the 55 Hornady. (Hodgdon lists 20.4 as max with the 55 Speer, but I decided to risk another .1 grain.). It got around 3150 from a 26" barrel and 3075 from a 22".
One handy thing about single-based powders is changing the charge weight also changes the velocity at the same rate. Which is why I suggested 12.5 grains: The math says it would get about 1900, give or take a little, based on 3100 fps for 20.5.

Sounds about right Juan...started using more 4198 in gopher loads besides the reduced ones. Good economical stuff.

ingwe,
In my 22" Ruger Hawkeye 12.5g of IMR 4198 and the 55g Hornady SP w/c clocked at 2,050 FPS. That's with R-P brass and CCI 400's. Your rifle, bullet and brass obviously could differ. Just FYI.
