A friend reintroduced me to the joy of shooting. It's been a long time so what little I knew has seemed to disappear. I picked up a 1997 (per phone call to Remington) 700 varmint with a 26" heavy barrel. I had the impression that the barrel should "float" all the way back to just in front of the receiver where a rectangular "lug" slides into a recess in the stock. I noticed a small buildup (it actually looks like an area that was left intentionally when the stock was cut for the barrel) just above the location of the sling lug and this is where the float, using the old dollar bill trick, ends. Any insight would be much appreciated.
