Then you can make yourself a set of K baffels that way your can will be smaller but just as effective.
here are some pics of the baffel desgine I use
Thats a basic K baffel desgine with a few little extras added to make it a little more effecient. That one is made from 718 Inconel which is very expensive but the absolute best material for baffels if shooting on full auto or subject to extended abuse of high caliber like the 300 RUM. You can use 316 SS for your first two baffels and 7075 aluminum for the rest that way your silencer is as light as possible ,that should last longer than your barrel and if not you can easly make more.
The old style that uses just flat washer type baffels and chambers is also very effective but like I mentioned it may take a little bigger can to be as effecient
