It may be an ammo problem. This afternoon I tried the 3 1/4 dram in my Super 90, and it wouldn't cycle in it either. I am going to try some Remington Premiers tomorrow and see if the SBE will cycle them.

I was against my son buying the SBE, but it was mostly his money (I had to front him some). He did get a "good deal" on it though. The gun is camo and has some "rub marks", but it is smooth as glass when you manually work the bolt.

I have had a stainless Sure Cycle tube in my Super 90 for years. I installed it after having to work on my cousin's Super 90 with a rusted up, gummed up cycle tube. I figured I would change mine before I had a problem.
