I have a very good friend who started out shooting model 12's as a kid probably in the sixties. I have a Remington model 31 and an Ithaca built in 1976 that shot left. He had a large tool similar to a gear puller and he bent both barrels. He got the 31 on the money in one try. The 37 just kept springing back. We gave up on the 37.

So many guns, so little time!
