[QUOTE="Paladin300, post: 2354490, member: 115299"] “If your running suppressed you can treat the length of your can as extra barrel inches. A 20” barrel with a 6” suppressor should run pretty much like a 24-26” barrel would. You shouldn’t loose to much velocity. For your application I would probably go 7 SAUM.” Let me apologize for the above statement. I posted it without clarification for my reasoning or fully thinking it through. I was in a hurry and trying to just offer a quick opinion, but that is no excuses. I have already stated my experience and reasoning below but I will clarify the above statement here. It is true that you cannot treat the length of the suppressor as barrel inches in a direct way. An 8” suppressor will not give you an extra 200 fps. That said, “If you are shooting a magnum cartridge in a 16-20” gun unsuppressed, IMHO, you are wasting your time. You might as well just run one of the standard short action cartridges because there is no advantage or place for all that extra powder to be burnt up or go. By adding the suppressor you are able to run full magnum loads as well as gain some back pressure which depending on the suppressor and how it is mounted will result in an extra 20-60fps increase in velocity over an unsuppressed barrel. The average is about 25-30 fps depending on the suppressor. IMHO if you are going short barreled magnum you need to have a dedicated suppressor for it and do your load development with the suppressor on. I think you will find as I have that you give up less velocity than you would imagine. I’ve only had experience with my form 1 titanium suppressor and a couple of those I have had a chance to shoot, a Griffin Armament and a Dead Air, I don’t know or remember the models. They belong to an acquaintance and in truth they are not my obsession. I like them but don’t live for them. My experience has been that my particular gun suppressed only gives up about 75fps to the same rifle before we cut the barrel off and suppressed it, not a significant amount. Which for clarification, was the point I was trying to make. Admittedly, I have limited time and experience running suppressors but I have 35+ yrs experience with various barrel lengths and cartridges and was just trying to offer an opinion and give some encouragement to the OP. Build a 7 SAUM or something equivalent, pick your dedicated suppressor and don’t worry to much about what you will loose in velocity. It won’t be to significant at 20”s. It will be worth it. Thank guys for correcting me and humbling me a little and again I apologize for the misrepresentation. Blessings [/QUOTE]
