Agreed, it will be going back. It’s 1/2 year old. I’m just waiting until my intended new custom 12ga comes in, in Feb. When I get that gun, this one is getting shipped back. Until then I’m suffering with it. It’s an a400 lite, so it could behave differently statistically to the other a400’s. I have other Beretta guns and they are all perfect, (except this one). When my custom one comes in, I’m sending it in to Stoeger Canada, but until then, I can make it work fine if I used Challenger 12ga 7.5 2 3/4. It works well now with that ammo but doesn’t with... well basically anything else I’ve tried, and I’ve tried a lot. Thing is I had a problem with the first of this model I got in, and managed to return it to the retailer within 7 days. THIS was the replacement, and I didn’t get a chance to trial it wothin the retailer’s timeline, so I will sent it back to Stoeger eventually. The a400 lite has a bad design or I’m unusually unlucky to have two act the same, the second being the replacement for the first.
