Well I finally pulled the trigger on an H&R Pardner pump compact in 20 gauge a couple weeks ago. So far I've run a box of Winchester universal 7 1/2 shells through it and it functioned just fine. I worked the action fast and slow and never had so much as a hiccup out of her. I shot from varying distances and got good patterns from the modified choke. Overall I'm impressed with it's reliability so far and I'm anxious to try some buck shot through it. I'm glad I took a chance on this gun as I don't think you could beat it for the price of $159 NIB.
