I earned a match bump to M and I shot classifiers for my GM. I think neither mean jack$hit. I think this is a live in the now sport. Shoot right now. This weekend 3 GMs including: one old school, one new (me), and one hands down without a doubt GM shot a classifier at our home club. We all shot high A% and were within 5% of each other for the stage in the match. The classifiers are just a stage... the scores are jacked up high now. I am not going for GM scores... I’m just trying to shoot my best match.
I have reshot classifiers... hell I think everyone has shot a bunch of the same ones. Some classifiers are more popular than others, some can’t be set up inside, small ranges use the smallest bay for a classifier. Is what it is. Also if you have never practiced classifiers then maybe you should. There is a lot of fundamentals, lot of loads, and procedures, draws, start positions... shooting makes you a better shooter. The classifier book is a good resource.
If you want a class bump shoot like your hair is on fire and legit. Shoot a bunch of majors and match bump. Or don’t, I don’t care. Shoot your best match, win if it works out.
