I think alot of it is in the grips as stated before. I have ruger security six with skinny grips on it, I do like the feel of the gun and the recoil is manageable, but when shooting my blackhawk in .41 magnum it isn't nearly as bad.
I don't like shooting at a covered range with anything, here in the country we have some ranges that are covered and I don't like them at all, luckily I have a 100 yard range here.
best advice, find someone with enough land to shoot on and ask them real nice if you can come shoot there. Try craigslist if you don't personally know someone. I once shot a deer on the farm out my door (legally with permits) using a ruger 10/22 I didn't have the muzzle all the way out the door, I will NEVER make that mistake again. I can't imagine shooting a "big gun" inside with no hearing protection, it would have to be awful. I bet if you get to shoot outdoors you'll like it much better.
