I cannot see how IR 50 50 is much different from RBA (which no longer exists). There was the 25 bull target scored best edge with an X if you punched the center dot. So the best possible score was 250/25X. The Xs were used only as tie breakers.
I was never a competitor but I watched a few competitions and have shot many RBA targets as a challenge to myself and in friendly competition with friends. My best ever score on an RBA target was 248/10X . That was shot with an Anschutz 64 Action MPR. with a Weaver T-36 and Eley Match (Black Box) ammunition. More often I have shot decent scores with my CZ 452 and its Don Stith Sporter class stock and cheaper ammo such as SK Standard Plus.
After a five year layoff from shooting (health issues) I have gotten back to the range this winter. I already bought three new rifles including a wonderfully accurate Anschutz 1761 MPR. Going through my gun stuff cabinet, I found an unbroken pack of 100 RBA targets, so with the CZ and the new Anschutz I will be able to keep busy for a while. I confess, at age 76, I am not really interested in any high level stressful competition, such as you all write about here. Here are those two rifles:
