I ran out of the Federal "Match" primers after my forth IBS 1 K match. I started using regular Fed 215's. After 10 more matches, plus the IBS Nationals, I could see no difference. I wouldn't sweat it and just buy the regular 215's. I guess I will buy some if they become more readally available, but only AFTER I finish the 5000 regular 215's I baught this summer. You can switch back and forth between match and non match primers, but be carefull when switching brands.....as loads can change dramaticly!!!
