I am a high school science teacher, so I have to fit in hunting days on a very tight schedule and trying to get time off is a major pain. Buck gun season started up near our place in the mountains recently and I took a couple of "personal days" off to take advantage. I rushed through to try to make sure that the ammo I had loaded for my handis was working like it should and that my handis were ready to go. I noticed on my 500, that I had not sanded down my acraglass pillar bedding job ala M. McPherson. This, along with a recrown, had turned the 500 into an accurate shooter. I sanded it down. Well, all of a sudden I was back to a 3-4 inch spread at 50 yards. So, in a panic, I decided to try RTV bedding the entire forend. Did it restore accuracy? I don't know - it did not quite completely cure in time to take it hunting. I had to switch to my old pre-safety Marlin 35 rem lever gun instead. Moral of the story - if what you do works - even if flawed, just leave it alone. What an idiot. I was all set to take my nice compact, relatively light 500 up a rather steep mountainside -but stupidity intervened.
