I personally have not shot the R.E.A.L. but my hunting partner, back in 80s, had a 50 Renegade and that's, what he swore by. I've always liked the looks of them, but never cast any bullets, so I stuck with off the shelf bullets.
A lot depends on your eye sight, a good rest, wind, how the light is on a given day. And, it might like another bullet, better.
