I bought my first DA revolver, a 7.5" SRH in .454 Casull, several years ago because of the excellent ergonomics/engineering and the fact that it would also launch my favorite round, the .45 Colt. I did have some ammo related problems - those spent cases of early Hornady and MagTech ammo were hard to extract - a small rod often being needed. Hornady admitted the fault, soft brass designed for more reloading, and actually replaced my stock (#99 & 00 lot numbers) with fresh gratis. Cleaning those cylinders post .45 Colts is important.
Oddly, the SRH is still less expensive than the RB new... American made vs Brazilian... go figure. The SRH is made from a higher strength steel - and, mic those cylinder separations and wall thickness of both - recall that the RB is regular SS. The SRH wins in that comparison - it 'looks' thinner because of the additional hole... (Count them... the SRH is a six-shooter!). I have witnessed, at the range, several Taurus products with significant operational problems... but, oddly, not the .454 RB. I did have a fellow shoot my SRH and then his ported RB - he said my SRH had the lower recoil!
I bought a 2x28mm Weaver H2 handgun scope for both my Ruger MKII and SRH. After the SRH's scope slipped once, I coated the inside of the rings with a thin coat of rubber cement. I have had no problems with it since... sadly, I cannot say the same for the .22 MKII - it continues to shake the mount & rings loose! That scope really helps my 'mature' eyes!
My favorite .454 Casull round - albeit a time of production variable as to it's mv (initially 2,000 fps, then 1,900 fps, now 2,000 fps again...) - is the Hornady 240gr XTP. The latest batch I chrono-ed averaged 1,985 fps. I produced the best 5-round groups with those: 1.625" @ 44yd indoors and 1.5" @ 50yd outdoors - from burnt sandbags (Significant side & muzzle blast - fire hazzard indoors!). By comparison, my .45 Colts have problems grouping better than 5" at 50yd, possibly due to the barrel's slow twist (designed for higher speed .454 Casulls).
My SRH 'broke-in' to be quite good, DA & SA. I tried to improve the DA trigger with Wolff reduced power springs - the OEM hammer spring was returned to duty after a ftf... you definitely don't want to hear a click when you are expecting to launch a .454 Casull round. The OEM grips are excellent, ergonomically, and add to the techno-ugo looks of the SRH - which I like. Yeah, no question... I'd buy another one! In fact, they look neat with a cut-down barrel...
