Really only one question to ask yourself, are you shooting offhand or not?
I'm experienced with most things 44 and the 77/44 recoils way more than one expects and must be held still until that bullet exits. There is some flaw with low bullet velocity, rifle weight, and recoil that seems to get you moving before the bullet clears. The 180gr Rem bullets work much better in this regard but the flame is something.
On the plus side, the rifle is one hole accurate. Each and every rifle I've tried, with tons of different ammunition is one hole accurate, Only when held down.
I'm gonna talk bold here and say unless the fella weighs about 200lbs or better, he cannot shoot the 77/44 worth crap without being braced. Nobody here will convince me otherwise because I've seen enough different sized fellas shooting it.
If you drop that 77/44 into a Boyds Laminate its a different animal but changes the whole trim feel of the plastic stock.
Its a hell of a rifle but for shootable loafing rifle the 77/357 is better. A couple of years back I did a 44 Rifle cleanout and the decision came down to accuracy and how shootble it was. Believe it or not, the Henry BBS 16" Carbine is the one I kept. I sold some very expensive rifles that lost out.
If you can hold her still offhand with fullpower 44 mag loads, more power to ya. Otherwise, why have a brushpopper if you miss.
