subsonic and powders
good day all...i was reading about the 300 whisper which reminded me of the load data james calhoon sent with my .19 badger. his 32gr pills with15.6 gr of aa1680 gives a velocity of 3565 fps. another recipe was 32gr bullet with 5.5gr of blue dot giving 1950 fps...a considerable speed cut with just powder.
now the question: would it be possible to take an off the shelf 30.06 bolt gun,a 220 gr bullet,and use a powder to slow it to sub-sonic to use with a surpressor? |

It is done all the time for the 308. Sub sonic 220g smks as well as the 175 SMKs.
Here's some random info from another board. 100% uninvestigated, may blow up cartoon style, so I'd research it for yourself. Quote:

Never been around a suppresor but, I've loaded and fired a great many cast 115gr RN's
in my '06 and 4-5gr Red Dot. It's a great quiet, very accurate load that I used to teach lots of women & kids how to shoot the big gun w/o harm until the indoor pistol range shut centerfire rifle's down in there. Seems someone saw me doing it, so he blew a bunch of hole's thru the backstop with full powered loads when no one was around. Also, resulted in camera's everywhere in there too. Some yrs ago one of the CMP shooters used 150-165gr cast with around 15gr Red Dot and was the top scorer at most of the match's til he moved back east for a job. IF you try it, start low and work up, or get some data from the powder companies. What I got away with might not work for you.

4895 works well for somewhat reduced loads. For truly sub-sonic, I have started using Trail Boss almost exclusivley. Quiet, accurate and even if you could manage a double charge you won't be in any trouble., i.e you are using only 5 grains in a 308 to get the slow speed you are looking for, 10 grains is still no problem. Pretty much any rifle cartridge can handle a cse full without causing an over pressure situation. That is NOT true for Blue or Red dot and most other popular slow load powders.
