very pleased with cfe223 in my .35 whelen. 64.0 grains gives me 2700 fps with a 250 gr bullet. About 200 fps faster than anything else.
That is my experience with it and 8x57 with 170 and 180g bullets. I use a Lee Perfect Powder measure. Not hunting this year. Good luck !!I have not noticed any stickiness in loading this powder. I use it in my 35 Whelen behind a 225 Sierra SBT with great accuracy and phenomenal velocity for this old timer. Will use it this coming November on Elk. Meters like water.
