I realize you guys are talking about the 44-40, I used a 38-40 Uberti 1873 [24.25 in barrel] to take a 98 pound doe on the 28th of November. I used a Remington 180 gr factory load, shot all the way thru at 41 paces, was kind of surprised it went all the way thru to be honest, not sure about the velocity. Guess I should have listened to my DAD, he used a 38-40 for 40 yrs for deer using 2400 powder.
