Subsonice 308 with 168 gr. and H4895

[polarcow]

Did a search and didn't find much. I know this is very specific but I am trying to use the same bullet/powder combo that shoots best in my rifle now, just loaded down to subsonic speeds. So, anyone have any experience with 168 gr bullets and h4895 trying to stay subsonic? I do not have access to a chronograph (yet). Thanks for any info.

I don't think you'll, safely, get subsonic w/ 4895...

Go to the Hodgdon's website and check out their loading data for Trail Boss powder. Very bulky pistol powder primarily intended for what were originally black powder rounds (45 Long Colt, 44/40, etc.), but seems to have some good application in subsonic loadings of modern centerfire cases as well.


And no, the only way to do a subsonic load with 4895 and a 168, is to shoot it at 1,000 yards. It'll be subsonic when it gets there. You need a much faster powder for this application.

Hope that helps.

Well in that case, what are your guys favorite powders/loads for subsonic 168 grn. bullets? or is everyone using heavier rounds?

Trailboss is pretty much the go to poweder for subs in a .308 I would also suggest stepping up to the 180gr Hornady round nose, 175SMK etc. The heavies tend to do better as subs.

Would trailboss also work for 223?
