Gentlemen:
On one of the websites I frequent (ammoguide.com), I came across a loading for a 50/140 Sharps, a cartridge and gun I've always been in love with. A 515 grain bullet at almost 2000 fps. and 5002 ft./lbs. of muzzle energy. Now, that's a warthog load. Right in there with a .458 Winchester. Bet the recoil is...memorable. It's a smokeless load; don't know what powder.
To keep this post within the parameters of the Darksider veiwpoint, one of Sam Fadalas' cartridge loadings for the 50/140 (with BP or Pyrodex cartridge) w/670 grain bullet produced around 3500 ft./llbs. of muzzle energy. I don't have my copy of Fadalas' book handy, but I remember it said that with equivilant volumn loads, the bp out-performed the pyrodex handi-ly. Another serious Warthog load; should kill anything on this continent that might want to kill you back.
I can't afford 3 grand plus for a rifle; have to stick with my .50 and .54 front stuffers at present. If the gods of smoke and thunder should smile at me, I expect that a Sharps 50/140 would be in the offing. Any pards out there have any experience playing with one of these?
