Keep it High Road, folks.
We're talking in circles, since we're all saying the same thing just a little bit differently.
Facts we agree on:
1. .50BMG rifles designed to be fired from the shoulder do exist.
2. Some of the .50BMG rifles in production are single-shot models.
3. Recoil from a .50BMG cartridge is heavy, but most .50BMG rifles in production use a muzzle brake, a specialized recoil pad, and their own considerable mass to make firing the rifle manageable.
4. H&R Handi-Rifles currently in production probably don't have the strength to withstand .50BMG fire.
5. H&R Handi-Rifles currently in production don't have the muzzle devices, recoil pads, or enough mass to tame .50BMG recoil.
6. H&R COULD make a single-shot break action rifle that had the strength, mass, and recoil compensation devices to make .50BMG fire possible without harming the rifle or the shooter.
7. If H&R produced such a rifle, it would be safe to fire and reasonably manageable. Their lawyers would see to that.
8. If H&R produced such a rifle, it's size and weight would probably make it a "Handi-Rifle" in name only, since it probably wouldn't be very "handy." H&R's single shot rifles and shotguns are nice little "walking around" guns to carry in the field. I carry my little H&R .410 Tamer around with me. While an H&R single-shot .50BMG would certainly be portable and light enough to fire from the shoulder in a standing position, I don't know if it would be much FUN to carry around in the woods. Then again, I imagine most of us would take such a rifle to the range, since .50BMG is a bit strong for a "walking around" rifle anyway.
