Somewhat quieter.......

#1 Post by Ray » Wed Mar 25, 2020 6:13 pm

7.62x39mm and .223/5.56 nato loads......

Recently I tried some subsonic 7.62x39mm factory loads in a 9" barreled AK pistol and it is much easier on the ears than standard loads.

The downside is .40 s & w level ballistics and won't self-cycle but a compact, easy to point/maneuver 30 shot "bolt action" is still a viable homestead defense tool......

I am trying to load my own along this line with trailboss, red dot, and 2400.....subsonic speed is not absolute necessary just quiter/milder for shorter barrel length use.

As for .223, I am going to try some faster burning powder rate .221 fireball loads.....needless to say, a 8" barreled ar-15 with normal pressure loads is not only egregiously loud but has a disorienting cuncussionous blast when fired indoors even with adequate hearing protection.

Your thoughts and or advice ?

For .223/5.56mm try 4gr Trail Boss with a 55gr FMJ. Got that load from the Hodgdon web site. Try looking there for subsonic 7.62x39 loads. HTH

I take that back about the 7.62x39 subsonic loads, looks like they don't have anything like that. Try playing around with Trail Boss, I wouldn't go higher than the shoulder with the TB powder. Good luck.

I haven't made any for an AR, but I did make some for my Mini 30. A little Unique and a .32 DEWC shoots great, but the same thing. Straight pull bolt gun, but very quiet. Even more quiet in a 7.62x54 Mosin. :D

I don't have those problems with my stop-assault rifle.

13 to 14 grs. of 2400 is showing promise in both cartridges. This is not a subsonic load by any means, nor even a reduced load but it certainly seems milder and has the advantages of being tested and sanctioned by the manuals and actually self-cycling the action as designed.

5 grs. of reddot in the .223 and a 40 gr. softnose meant for the odd .22 t.c.m. is my next experiment.

Had a trailboss/52 grain cast bullet load that was subsonic and shot pretty good in my single shot and bolt .223 but never tried,in my gas guns. Lost interest when I finally got another 22 Hornet. That cast bullet over a dab of Bullseye does a great job at quiet pest control.

Ray, I've been using Blue Dot in 223 with a 34gr HP and 50gr SP, reallly happy with the accuracy and velocity. If you google "Blue Dot loads for 223" there is a couple good write ups. One guy has data and pressure for up to 60 grain bullets.
30/30 Winchester: Not accurate enough fer varmints, barely adequate for small deer; BUT In a 10" to 14" barrelled pistol; is good for moose/elk to 200 yards; ground squirrels to 300 metres

250 Savage: The Original short action, compact, high velocity cartridge.
