Which 300 gr. bullets are you loading? What's the COAL?Well to be perfectly honest we never tried that.
I don't know any others who have either as far as I know. As I recall the burn rate on that is pretty close to where old H570 would fit. Reloader 26 seems to work for some also. We tried RL 33 also but Retumbo works better for us. The old h870 and wc872 can be used also but cold weather can cause issues with those. Im sorta sorry we didn't use a 32"
on my sons gun.
