I don’t normally care to be considered stupid, but in this case I suppose it fits. I got a rather expensive Briley choke stuck in my BT 99. Now I’m very careful to lube the threads and generally keep my gun clean, but in this case something happened that I can’t explain. I had about a flat through the choke and decided to change it out tonight. Now a flat doesn’t seem like much to me to stick a choke but it did. I broke a T handle Browning wrench trying to get it out. I tried oil, Remington action cleaner, heat, nothing would budge that choke. I finally had to put the choke in my bench vice on the gun and gently turn it to break it loose. It boogered the choke a bit but it finally broke free. That choke won’t be going back in the gun. So I took some anti seize grease and installed my other choke in the gun. From now on, I’m gonna check it between rounds. I figure I lost a good hundred bucks being careless.
