Accuracy.
Generally speaking..
Slick lubes need more powder.
Most RB rifles shoot best with a "heavy" load. Back when I started shooting 70 gr of FFF was very common for 45 calibers. I shoot 90-100 in 54s and 70-90 in 50s. FFF GOEX usually needs 100 in Douglas barrels.
Most modern RB barrels are twisted too slow. 48 is perfect for barrels to at least 54 and probably to 62.
High friction loads. Water soluble oil mixed 1:7 oil-water, then allow the water to evaporate, or teflon will usually shoot best. But require wiping every shot. As a friend said at one of out "turkey" matches, shot off a "plank rest". you don't have to wipe every shot. You only have to wipe every shot to win. High friction increases "load inertia" and will usually lower the standard velocity variation. A heavy load also increases load inertia.
Low velocity loads are not the best for hunting unless you are shooting at pistol distances.
My cupped breech Don King FL Hawken, 38" .535" ticking patch, Neatsfoot Oil lube, 90 gr of FFF Swiss makes 1900 fps.
This load will shoot into about 6-8" at 200 with no wind. Slight breeze, anything you can feel, blows the group.
Watching people try to shoot a "turkey" match with light loads has convinced me that you need a pretty stout charge for best accuracy. But people gripe if you shoot "too much powder" at matches.
Jim McLemore told me my heavy 50 cal barrel (his gain twist) would shoot into the same hole at 100 with 120 gr of FFF and a teflon patch. I usually shoot a .500 ball in this rifle and dried WS oil 100 ge FFF Swiss. It shoots well. Best 10 shot string was just under 4.25" at 60 yards. And I had a puff of wind put one out 2" down wind.
Duct taped scope mounts will not hold the scope well enough. Gotta be bolted down.
Holes can be plugged later with screws and am "asterisk" star pattern engraved over them.
This was a sighter target I left up and put the score "turkeys" over to give a group after the match. 60 yards plank rest. Probably about 12 shots total. 2 sighters and 10 for record. Barrel sights with shaders. Can't do that today but they are supposed to fix it in October (the eye). 1 1/4" x 44 McLemore 50 cal. barrel.
A good RB barrel should be able to do this. But swamped barrels are less accurate generally.
