You dont say what type of match you are really interested in shooting , The club i belong to shoots ARA and we have some very devoted 22 shooters . The guns and rests and related equipment on there bench must total $5000 easy , shooting $100 a brick 22s. I just dont have that type of money , My CMP kimber has shot groups in the .18s but more often in the .5 range and that wont compete .
If your club shoots IR50-50 , My felling is that it opens the match to alot more people due to classes that allow less exspensive equipement to be competitive.
