None of my six $40 Simmons 4X ProDiamonds have failed yet. The one on my little X7 has seen
well over 1,000 shots. The one on the .45 GM/TC Renegade has seen something like 800 shots.
(When I clean the
Sinful Sisters, I pull the barrel from the stock and dunk the breech end in a bucket of water - scope and all - to pump the bore.)
