Wanted to see if I could get a plinking load using the Lee.450=200 gr RN bullet designed for Black Powder Handgun use.
Tried PP up to .462 and using a load of Trailboss. in a 45/70 . Got 6 inch groups at 25 yards and could not hit paper at 50 yard. Back to the drawing board. Maybe the Lee 255 gr FN 45 cal would would better, Just a thought.
