300 BKO Subsonics... What's the smallest pill you've loaded?

John Gault · Jul 28, 2016

I would like to hear personal experience on the lightest subsonic load you had luck with. What grain, what manufacturer.. I've got some 1680 powder. Having trouble finding 208 grain pills at reasonable price or quantity. What are my options guys.

I have been loading some nice subsonics for my 308 using the 150 and 168gr pills, do you have access to a chrono? it shouldnt be to difficult if you do to load 3 rounds at each powder level and work your way down, make sure you dont have a can on when you do.

Bolt rifle you can load anything subsonic. What are you shooting?

Yes, chrono in the house.. 168 grain and 150 grain sound good from an availability/cost perspective.

Ive ever been able to get subs under 170 to cycle reliably in my 7.5" and 8.5" AR's and Ive got every kind of powder you could imagine.

90gr XTP with 4.5-5.0grs of trailboss single shot out of an AR or bolt gun.

Is that suppressed or non suppressed...?

I dont shoot much , if any, non suppressed 300 BO. Pretty much everything I shoot is going through a SIG 762Ti or a Silencerco 762 specwar . Ive had great experiences with 175+ grain in the SBR's but under that its pretty spotty usually short cycling.
