Hey guys I've owned this model 29-3 for a couple years now and my dad owned it about 25 years before me. I come from shooting heavy loaded ruger 44's and honestly don't know an awful lot about the smiths. I know the model 29-3 is a pre endurance package gun, and it's beautiful and don't wanna shoot it loose. Since I've owned it I've shot 240 -250 hard cast with 10 grains of unique. But last deer season I bought some 240 grain federal fusions and they worked great on the buck I killed with them. Also far more accurate than my hard cast. So I'm thinking about reloading some 240 grain xtp or similar for this deer season with 19 - 20 grains of 2400. I'm mainly thinking 1250-1300 fps out of the 8 3/8" barrel is my goal. My main question is will a pre endurance package smith hold up over the years with this load ? I usually put a few hundred rounds a year through my handguns from 25 to 100 yards practicing for deer season. She is a pristine beauty and I don't wanna shoot her guts loose. I'm not looking for the big heavyweight bullets. Also how bad is a healthy charge of h110/ win 296? Thanks for any help guys.
