If you can’t use smokeless I would try to get an encore with a 45 cal Barrel. Mine is from bergara, and with a 200 gr shockwave and 120 gr by volume of bh209 I get 2400 fps and 1.25 moa. Sighted in 2.5” high at 100 puts me less than 2” low at 200 with 1400+ fpe. You could shoot the same bullet in a 50 cal with the right sabot, but you will lose some speed.
