In reading an earlier post, I missed the answer. Has anyone any experience shooting CMP Tactical Rimfire competition? if so, which tactical 22 rifle do you use, the 10/22 tactical or the M&P 15-22? The critical distance is 50 yards at a 1 7/8" 10 ring. If someone likes one over the other, are modifications necessary? Which mods did you do? Thanks for any responses.
