I know this is going to sound stupid but have you tried other ammo's other than the Hornady? I've never shot Hornady ammo although usually I hear how great it is. However, I know the Browning BAR I had was very picky on ammo. It shot them all fine but it was not accurate with many. I found out it ended up liking the Federal Fusions best with the Federal Soft Points in second with groups a bit bigger. It was all over a 8" target with Winchester Ballistic Silvertips and with Remington Core Lokts. Not sure if other types of ammo will help or not.

Also like said what about cleaning? I know if you shot a box of shells through my BAR it would be super dirty in the barrel. I'm just not sure how it got soo dirty soo fast but it did. It was bad for that.

I have been unhappy with almost all the Remington Products I've owned or dealt with. I can think of one exception and that's a buddies 1100. However, the rest have had a lack of quality control and some of them have needed work right out of the box. Others worked but had parts that never should have made it past quality control.

The Browning I've had and the ones I've dealt with have all been of much higher quality and seemed pretty good. A buddy did have a problem with a Browning Gold though where his jammed all the time. Everyonce in a while you just get a lemon with anything.
