I'm fortunate to have a range nearby with a 100 yard indoor range, so while it is still loud, it is expected since everyone is shooting rifles. I have the same problem when I bring my 45 Colt and 454 Casull revolvers to the range. I will warn shooters in the lanes adjacent to me that I'm shooting a big bore or advise the RSO that I'm doing so and see if they can put me next to the wall or away from other shooters if possible. Unfortunately it is still an indoor range and folks should expect it to get loud.
