Mostly my handloads, a 240gr doing ~1150fps which I would consider the upper end of low magnum range. Hottest rounds I run through it are Hornady Custom 240gr factory loads, rated at 1350fps.what kind of rounds do you mostly shoot out of it. low magnum range, mid range magnums or 44 spcl loads
Generally, the older the gun, the more collector value it has. Much still depends on condition, but SCSW usually gives a substantial premium for S prefix revolvers, especially ones like M27, M29 and M57 and M58I wasn't aware that the S-prefix added so much value, mine is actually an S-prefix.
i do have a 29-4 8 3/8 with full underlug and it feels nose heavy. the 6.5 half lug felt better balanced. shooting wise i wouldn't know. this one has the endurance package and you can shoot golf balls with it at 25 yrds if you have a good day.
