FYI - My shooting buddy, John was shooting Remington Thunderbolts through his Remington 121 when a round malfunctioned and jammed his rifle. A quick trip to our gunsmith and after about 20 minutes he had the jam fixed. The Thunderbolt brass "exploded" through the firing pin strike on the primer which prevented the shell from being ejected. (The metal was visibly protruding from the bottom of the shell.)
Our gunsmith's evaluation: The brass was too thin and we should stay away from Thunderbolts if we value our firearms (fingers, hands and eyes). Thought I should pass this experience along as a forewarning.
