I have an 83 in 454. And yes it is worth the money. I also have Blackhawk's in 44 spl and 45 colt. On the 44 the BH is as accurate as the 83 is. The 45 colt not so much. I doubt I would spend the extra money for a 44 spl but the colt or a 44 mag I would if I needed that little extra in accuracy or intended to shoot extra heavy full snort loads. It really depends on your own personal needs. I needed the 454 to be super accurate and tough, That's why I bought it. I don't need my other single actions for top tier nor do I load them to that level. My 44 mag redhawk will kill anything I want out to my self imposed limit of 100 yds. Will a FA do it any better. Yes but is that extra margin worth 3 times the price to you.
Don't get me wrong, sometimes I want the best and if I can afford I buy it and it makes me happy to own it, need had nothing to do with it. If and when I get into higher pressure rounds like the 454 then I would consider another FA or might try a BFR.
To answer your question, 44 spl=no, 45 colt=yes if I was shooting Ruger only load levels and no if shooting standard level.
Have fun on your journey.
