Excellent gun, what a tank! As far as Factory rounds go, mine does extremely well with Hndy 300g XtpMag. Recoil for me with this load, even in recent years, is still easily managed with gun's nice balance & weight, mine has the most recent stock 'finger groove' rubber grip but like original grip on my twenty year old 44 too.
Same bullet is also extremely accurate charged with w296. And want to try IMR4227.
Another accurate bullet for me, is a good fitting 250g RFP PB cast, where psi range is matched well with bullet's hardness. This has worked wonders in Ruger SRH as well as a scoped FA m83(130 yards) and looking forward to trying it in 6.5 inch SBH Bisley.
Have also enjoyed a red dot on my SRH using custom rings, amazed with the results. Like other powerful DAs, but Ruger is my favorite. This gun is a DA handgun hunter's dream. Have fun.
