I'm not picking on you, but Kohler makes plumbing fixtures, Kolar makes shotguns. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" /> And, Chaddick's is in Terrell, Texas. I don't know of a Chadwick's in Tyler.
Now, back to the topic at hand, unless the barrel is actually bent (check it by holding it up with the image of some kind of a straight object, such as a telephone pole, reflecting down the side of the barrel, a bend should be fairly obvious, the reflection won't be straight), I wouldn't bend it for such a small correction. 4 inches low at 20 yards equals about 3/16 plus a skosh correction in comb height. As Sitka Deer said, you can get a pad and fit it to the stock. For those of us who are country boys, 4 inches is just a few layers of duct tape from perfection, unless you ask our wives. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
