If you have the slow-twist rifling, the longer 'Minnies' don't stabilise well.
I use the one of the left next to a Lyman Minnie/ The solid is sized 590, it does great to 100, never tried a longer range at this time. Be an awesome close-in hunter if legal.
I do lube the big deep groove with 50-50
Then seat it atop a 1/8" Lube Cookie disc of 50-50, itself atop a greaseproof paper disc to separate from 70-80 grains Krank's Ffg. Seat right down until you feel the powder 'crunch' (do this always, NEVER leave an air-gap) Just enough barely-there crimp using a backed-out sizer-die with pin removed to hold the boolit enough not to spill out.
I shot 50 in a row and still had a clean bore with fully visible rifling before cleaning.
After shooting, I decap without using a die, clean brass in the ultrasonic and dry.
Don't need to ever flare the mouth or re-size, on about 25 firings now per case, no splits.
Bertram brass.
