Thanks for the info, people. I sort of tend to agree with Crimp's idea that the warranty is Springfield's way of saying, "if the gun fails because you tried to shoot a double load of Bull'sEye it's your problem, not ours". Personally I would rather shoot my reloads because the only problems I've ever had, or personally seen, have involved factory ammo. One was when a friend's .357 Smith and Wesson had the cylinder locked solidly in place when the brass on the factory loads backed completely out of the cylinder under recoil from the first two shots. The other was with some Remington 230 FMJ in my Series 70 Colt jamming back into the case when they were chambered. Or were supposed to be chambered, luckily they caused an FTF and when I saw the bullet half back in the case I said no more of these. I ran the rest of the box thru my crimp die and had no more problems.
