My Model 99 EG .30-30 likes these. 35 grains of CFE223 gives 2280 fps and a 10 shot group at 50 yards of 1 1/4 inches. She still has open sights. The Marbles tang sight is on the way.
I've used this powder with Sierra bullets and got very little copper in the bore. These Speers left none. The hi/low shot difference was 41 fps.
I'm lovin this rifle. Accurate, reliable and not at all fussy about loads.
