Finally got a nice day to shoot, tried 2 tubes, the Trulock .575" and an Undertaker .582", with 4 different Hevi-shot loads, the Rem HD #6, Hevi-shot #4 and #6, and Hevi-13 #6 Turkey, the best of the bunch was the Hevi-13 #6 in the Trulock, the Rems probably just as good, but with a few less hits in the spine.
Recoil with the Limbsaver was about like a 30-06, I was shooting in a t-shirt, shot 14 rounds of 3" loads, all 1¼"oz. I was a bit concerned about the high comb and beating my cheek up, so I sanded the top of the comb down ~¼", it didn't bother me a bit and eye alignment is perfect. Very happy with the final results.
