I absolutely love my A-Bolt rifles. YOU CAN NOT GO WRONG WITH A BROWNING!!! First off, you can get an A-Bolt hunter for much less than $600. Browning rifles come free floated and bedded from the factory. They will not guarantee MOA accuracy, but I have never had one that wouldn't shoot under MOA. I posted this picture earlier, but it is a three shot group at 100 yards from an A-Bolt in .243 that I picked up off gunbroker for $490 new with scope. The group is 5/16". There is actually 3 groups on that target I believe, that I covered up while I was sighting in my rifle.
The magazine issue is way over rated. The hinged floorplate drops down and the magazine clips into the floorplate, swing the floorplate up and there you go. I also have an X-Bolt Stainless Stalker in 7MM-08 that I picked up off Gunbroker for $740. I absolutely love this gun as well. I would check out the Stainless Stalker if I was you, it is fantastic! I hope this helps.
