My UM barrel is throated for the 88’s, which it doesn’t particularly like. The 77 TMK and 80 ELD-M shoot very well though, even with that long freebore. I wouldn’t stress too much. It seems like if your barrel doesn’t like one projectile, there’s others with more or less bearing surface etc that will.
Yeah, its not like 77 TMKs are close to the lands of a 556 or Wylde chamber loaded to AR mag length. Some jump isn't the end of the world.
