I shoot a Lefever E grade 10 a LOT. Mr.Wood loaded me up some stuff for it in #5 shot and I bought a bunch from RST as well. The old girl is heavy, but, as i have said here before, it forces me to slow down my shots and my kill ratio is higher. I killed a rooster at 85 yards, laser measured..a couple of years back, and replicated peformance on stationary clays...I think I posted those pictures as well. The big 10's are a joy to shoot...I just passed that gun, along with cartridges to my boy Tom, in Iowa..Joe Wood shot a 10 Parker last year with great sucess, and had a big ol Texas grin on his face every time it went bang....You will love it..
