Hey guys so I'm building a 50 caliber supressor for my 500 s&w handi rifle ( don't worry I'm building it to handle 50bmg should I buy one in the future ) and I still have to take measurements with micrometers to see OD of the barrel, but since I'm wanting to send it off soon for threading I was wanting to know the most common thread pattern used on the barrels for supressors and muzzle brakes.
Thanks |

I am so in over my head on this, but maybe some of my useless information can help you.
The diameter of the little one is .500 and the diameter of the big one is .510. The barrel diameter of the big one is about 1.5"-1.75" at the muzzle (I think) and the diameter of the little one is way, way less. The energy ratio is about 5 to 1 in favor of the big one, and the velocity is about 1000fps faster. The Mass ranges for the big one are about 650-820 grains, and the little one uses 350-700 grains, but most are 350 or 500 grains. The faster a bullet, the louder it is, the more massive the bullet, the slower it is because it's taking up power space. Threading a silencing device should be almost identical to threading a muzzle brake unless your suppression device fits over your brake. If you port your BMG you are going to end up losing too much velocity. At 5 times the energy, not knowing what I'm talking about, I'm going to wild guess you need 5 times the volume, but the barrel of the BMG is already near twice as thick as the S&W, so 5/(2*2) = 1.25 times longer and double the diameter.

i guess to muddy the water more  , im building the can to 50BMG specs as im copying a design from one of the guys over at silencer talk, the main tube will be 18" long, roughly 3' diameter, and i believe .175 wall stainless steel with stainless baffles. my thought process was to overbuild the can for the smaller round, so that it was a dual use can, kinda like if you built a 338 lapua can and were going to use it for 300 win mag. i know the guy who built the 50bmg can has worked successfully on his 50bmg rifle.

If you have the skills and the machine you can build it anyway you want
and yes if it's built for a 50 BMG it will work for the handy, it maybe a little large but it will work. You may need to make some sort of muzzle thread adapter For the smaller diameter barrel on the handy but it's doable. Don't let anyone tell you that it can't be done, if you have a dream and your creative you can do it. |

that can will be a waste on a 500sw if you build it to 50bmg specs. I have one of the lightest 50bmg cans and that thing would be obnoxious on a handi rifle. Its gonna suck with all that weight on the end. If your gonna build it, might as well build 2 of them, one lite and compact for the 500sw and a heavy big bastard for the BMG. |
