The seller handled it appropriately and we worked out a deal on a partial refund, all is well.
I ended up taking a dremel tool and shaving the parts that were bent in to get back to a somewhat decent looking circle and inserts now fit. I'm going to give the barrel a go next time I'm out and see if I notice any issues with barrels breaking or not being as accurate as I'd like.
If there tip were more expensive or if I already had the tools I wish I had I would have done similar to what was recommended previously. I would have looked for an aluminum/metal cone, placed some oil on it and stuck it in the tip of the barrel and hammered it until I felt the indent had been pushed back to normal.
Thanks again for the input everyone.
