I bought a used Handi-rifle in 280 Remington on Gunbroker. At the range it would not fire (factory ammo). I sent it to H&R for repair and had them put on a 45-70 barrel while it was there. I then bought a new Handi-rifle in 44 magnum. It worked for several shots, but then quit. Back to the factory for service. Both rifles work fine now, but I'm concerned about reliability. I would like to take the 280 to Missouri to deer hunt (I live in Indiana), but don't want to get there and the rifle not function. Is this normal or have I just had unusually bad luck? Any thoughts on the matter would be helpful.
