adively, reply #12, asked,
Terry did you see this?
Quote from: From the aforementioned link
SSK has produced the largest center-fire rifle in history, the .950 JDJ. It is a .905 [sic] caliber which produces recoil equivalent to shooting ten .30-06 rifles at the same time.
Well, yeah, so is there some kind of joke or mistake I'm not getting? The 50- lb rifle does have a hefty muzzle brake on it, and it was on some kind of sled. Future rifles will weigh over 100 lb. The 277 ft-lbs is probably a calculated value without considering the muzzle brake's effect. (I wonder if they added in the recoil effect of over 240 gr of powder gases, too, in the calculations.)
Even the "10 times a .30-'06 recoil" didn't seem outside the bounds of a quick reality check, if you figure the recoil of a heavy bullet (220 gr?) out of a light (7 lb?) .30-'06 rifle. Didn't calculate that energy, but both the M1 and the '03, at 9 lb, give about 15 ft lb of recoil with the 150 gr service bullet. So it's not a stretch to get to 27.7 ft lb (1/10 of 277) out of some rifle-ammo combinations. A light 12 ga shotgun gives you around 30 ft lb already.)
The thing was that I just didn't realize there was an exemption for >.50 caliber "sporting rifles" from the destructive device restrictions. (If I had thought about it, I would have realized that of course some elephant rifles are > .50 caliber. Duh, me.)
