Benchmark and 8208 can get 55s to shoot in many barrels. 69smks are some of the easiest to dial in as you almost never hear of difficulties getting them to shoot. I’ve even used RL15 with 55s with good results.
Johnny’s reloading bench on YouTube has a whole series on getting cheap 55s from Bob’s Bulk Bullets to shoot. It’s worth a watch if you have time.
