Hi all, I have a Rem 870, with synthetic youth stock set. In the past, I've used a butt-cuff to keep slugs available, but it isn't stable. I am considering a mounted (screwed-on) shell carrier on the butt-stock. Would you guys discuss this type of carrier compared to a side-saddle? If you prefer one to the other, could you share your thought-process on that decision? Thanks!
