The good stuff: I originally was using the stock Remington follower, but after seeing how thin the plastic was and dealing with a few tricky reloads, I ended up popping in the follower that came with my Choate extension tube. Talk about a major downgrade! The little polymer sucker jammed up even more than the stock Remington follower! I started looking around for something that would be more robust, yet move easier inside the tube. Long story short, this was the answer and it works like a charm!
The bad stuff: I got nothing. Sorry.
Overall, this didnt speed up my reloads at all, but it definitely make for a more fluid push into the tube. No jamming, no hesitating, the sucker just works. Good product.
