I have a Raging Bull in 44 mag and was told I can not mount a scope because of the porting(6.5" barrel.) Was maybe looking at selling the RB and buying a Super Redhawk in 44mag or 480 ruger. I was just wondering how the ruger shoots without porting. I will shoot 270-300gr loads in 44mag. Is going for the Ruger a good decision? And if I do go for it would the 480 be a better choice than the 44mag? Don't mind long detailed answers.
