I load 240gr XTP's in a 44 mag rifle for my sister in law. She shoots a Handirifle(slightly longer barrel than the 1894), her shots are 25-60 yds. I load full power H110 per Hodgdon manual, would say velocity is more in the 1700-1750 fps range. Not sure about a boiler room shot as she aims for the neck or brain(she likes venison). Always thru penetration with minimal meat loss. She never misses. Never recovered a bullet so can't say if it shed the skin. That bullet works excellently for her in a rifle. Always penetrating bone and some tissue, but not a lot of tissue. I have full confidence in the 240gr XTP at rifle velocities on whitetail sized animals.
On a similar note I use 250gr XTP's in my 45LC Handi, which has a 20" barrel. The bullets are constructed similar and are driven to about the same velocity, my shots are about same distance also. I aim similar to sister in law (I taught her to shoot) and have always had good performance from those bullets driven to rifle velocities as well.
