Love ‘em or hate ‘em, they shoot straight out of the box. I’ve never seen one not shoot better with the bumps removed, but many have shot so well I didn’t even mess with the bumps.
I still like a few platforms better, but they typically don’t do that from the start.
I had a 308 T3 that had speed bumps. I never did a thing to it and it shot ridiculously well as do all T3's. Current 30-06 T3x I am afraid to even clean it, scary accurate.
