did. 44-40 lever was 200 grs at 1200fps or so, about 700 ft lbs. It of couse didn't expand in flesh, so it wasted 1/3rd of its power on overpenetration. The men of that day were at least twice as tough as today's pussies, too. The 223 sp dumps ALL of its 850 ft lbs in the man, and its temporary gas cavity READILY demonstrates that it WILL damage fragile chest organs. At the sub 150 ranges of the 44-40's being worth a crap, the 10" 223 is a FAR more effective rd. At longer ranges the 44-40 lfp is a JOKE by comparison.
