Thank you for all the suggestions. I don't think the magazine tube was the issue. It's already chamfered, and the loading gate was sticking a bit even with the magazine off the gun. I ended up using an automotive shim to hold the gate away from the bottom edge while tightening the screw, and it doesn't seem to be sticking anymore even though it's still not centered.

I was considering replacing the magazine follower with a stainless one based on what I've read about the plastic follower becoming impregnated with debris and not functioning correctly, but it appears my gun may have come with an anodized aluminum follower. Is it something that newer Rossi's have, or do you think this is unique to this model?

I got a Lee Shaver donut type front sight insert and shot this at 100 yards with a few different loads last weekend. Overall I'm happy with the rifle and what it seems like it will be able to do. I'm really looking forward to getting a peep sight closer to my eye. The peep on the barrel has been just really tough for me to see through consistently.
