I built a single shot BMG on an AR frame once...wjich i lighter than a Handi. It wa s :...exciting :, but shootable.Spanky said:I'd like to see someone hang onto a 50BMG Handi Rifle.
On second though... Tyler might be able to hande it ;D ;D

Well....let's put it this way. I've built two rifles that I just dread shooting. One is a Spanish Mauser in .308 that I milled every spare scrap of steel off of, then made a skelatonized aluminum stock and the butt width is 3/4". It is a joy to carry on my mountain bike (before my knees finally went south) but was like shooting a meat clever....the other was the AR which was worse.Spanky said:

I have one of the slug gun barrels at a friends house now so we can use his lathe to chamber it for the 12FH when the reamer gets here. The FH is just a BMG case blown out straight, the head turned and threaded for a screw on 12 ga rim.
The Handi's don't have any trouble handling it so I occurred to me, someone may be using
a 500 barrel with down loaded BMG'.
The pressure isn't an issue but I wasn't sure about flex. The TC's can't stand it either.
yep i just didpeternap said:Since Tim mentioned the BMG in another post, has anyone tried a 50 BMG in a Handi?
That' entirely correct Tim and the reason the Handi's handle the FH well. The FH's are in the 25K region with Handi loadings. A BMG could be light loaded (Boy that's an oxymoron) to that level but that's one of those guns you would have to make sure no one ever accidentally fired a full house load in.quickdtoo said:Pressure isn't the only factor, case head size and pressure are the determining factors concerning frame strength, the larger the case head, the lower the pressure needs to be on an H&R frame, see bolt thrust on the Lilja site. The 500S&W has an operating pressure of over 50kpsi (SAAMI MAP 60kpsi, but the highest data I've seen is ~52kpsi) and an inside case head diameter of ~.501", that calculates to over 9800lbs of breech thrust, that's likely the safe limit of the SB2 rifle frame, the SB2 shotgun frame is likely less due to the thinner frame rail tops.
