Re: what's your best 223 subsonic load

Shooting a Sierra 65gr Game King with 4.6gr of trail boss is very quiet and very accurate out to 100. I had 12MOA of drop from my normal load at 100. I havnt shot it over a chrony yet but they loads got louder around 4.9gr of trail boss so I know I am close to the limit. These were shot from my 16" Kreiger Recce. These did not keyhole. The paper tore up but there are 5 shots in here.
Load data:
65gr Sierra Game King
4.6gr of Trail Boss
Wolf primer

i have used TB with my 308 but not with a 223 I have however used Blue Dot if you have any of it. Its shoots great I can give you some loads if you have the powder PM me.

My partner and I are using the Trailboss with 69 sierras bthp and having good luck with em. I don't remember the chrono data from here, but they held accurate and were stable.

Re: what's your best 223 subsonic load

the twist rate on your barrel will have to decide what size of bullets you can stabilize . if you have a fast twist you will be able to use the 75 - 69 grainers . i have some experience with loads using trail boss . if you want details pm me . HOWEVER BE VERY CAREFUL , HOWEVER , I HAVE HAD BULLETS GET STUCK IN THE BARREL , SO TAKE EXTRA PRECAUTION . GOOD SHOOTING
