The only down side I ever heard of is that you must take care when resizing the brass as it will collapse fairly easy. I reloaded thousands of them and really never had that problem. Its a great fun little caliber. Way back when, I shot a couple nice deer with one before I found out it was not a legal caliber in my area. Ooopppss.

Just picked up a 10' bull barrel in hornet for a contender. They are supposed to shoot good in contenders. Should have less noise and muzzle flash than some others.I get a scope on their I'll find out.
