sorry for bringing back an old thread.
1st of all the 500 is not that big of a deal recoil wise. I shot 2 boxes of shells (12 275 gr and 20 350gr) out of it in one day with no problem. Basically the next day (and a couple days after that) it felt like I had played catch with nolan ryan and used a 1st baseman's mitt. As for the gun coming up and smacking people in the forehead or jumping out of your hand, I highly doubt it unless you are shooting 450gr ammo or you're really small. The gun's recoil is more straight back than it is up.
2nd, azredhawk, you're watching too many movies. hahaha.
3rd HMcClellan thanks for clearing up how they stop the HP rounds. I always wondered about that. What is in the dry fire boxes to stop the bullet? as for that mythbusters show, it was on again this past weekend. basically the faster the bullet the more it breaks apart when it hits the water. as expected. the 9mm handgun made it like 8 feet, a shotgun slug destroyed their tanks. but when they went to the HP guns, including a .50 round, the bullets would only make it about 2 or 3 ft tops. the .50 round actualyl had it's copper jacket pealed away.
