.338 Federal?
.338 Federal?
Does anyone here have a .338 Federal? I just ordered a McGowen barrel for my LR-308 and am looking for subsonic load data with 285-300 gr. bullets.
Re: .338 Federal?
For 300gr bullets in 338 Federal, I use 13.4 gr of VV N110--about 45% fill.
You can fool all of the people some of the time, and some of the people all of the time...and those are pretty good odds.

Sorta in the ballpark on the info request.....I cast some 200 grain bullets in my RCBS mold today..........
8.1 grains of Trailboss came to ~1015 FPS
9.1 grains of Trailboss came to ~1065 FPS
Earlier tests using 250 grain Sierra Game Kings, 13 grains netted ~ 1015 FPS.

I should have noted that it is for a semi-auto rifle. I have also found that no subsonic load will cycle this semi auto rifle. So it's back to supersonic loads. Thank you to those who responded.

45 raptor would probably be your best bet for a subsonic semi auto AR10/LR308
