I recently picked up a B.Mag from Fine Firearms at the Del Mar Show. I have only sent a few rounds through it since ammo has been hard to find. I'm just wondering if anyone has one and how accurate it is. A 2 1/2" group at 100yds has been the average. I was expecting much better performance. I've seen posts elsewhere that some people say they are tack drivers and others can't keep rounds on paper. Hoping someone here has some info.
