[GARD72977]

I bought above 311-206 For Garand I have com In. Thought it might work for a1-8 twist Black out. Anyone using this

I used a few of the 299 bullets when I had my 300 bo they shot ok but my Lee 185 shot better mine had a 12 twistbarrel so no subsonic loads

[GARD72977]

I shoot an encore with a 1/10 twist. It really shoot good. Have not Shot any thing above 170gr in it.

This AR has a 1/8 twist so I thought a 206 gr running sub sonic might shoot pretty good. Didn't buy the mold for it but hope it works.

The 311299 was designed, back around 1906/7, for the .303 British, which was at that time one of the chamberings for Winchester's Model 1895 rifle. Winchester used a 1-12 rate of twist in their .303 barrels, and the 299 seemed to work well with that. It also worked satisfactorily in the 1-10 twist of the .30-40 Krag, .30-'03, and .30-'06, of both Springfield and Winchester (and others) manufacture. I can't really say what it will do, good-bad-or-indifferent, with your 1-8 Blackout. Might be getting close to its limit, stability-wise, but certainly worth loading up a few and seeing what happens.

I use it in my bolt action 300 aac. Super excellent subsonic bullet

The only concern I would have is the diameter of the nose. In an AR, I have been trying to use the Lee 7.62x39 mould and the nose diameter is to large and a small amount of lead is scraped off and kind jams up the chamber, not reliable. If I have PC on the bullet, every other one will not go into battery with the large nose diameter.

Just looked up the nose diameter, looks like NOE uses .300... should be fine. The shank is pretty long at .435, so they will have to be seated fairly deep.

You have the twist backwards. Heavier (longer) bullets need faster twist.

1/8 would be good for subsonic. The BO will not push a heavy bullet very fast anyway.

I have NOE's hollow point version of this mold. I think the nose in practice is a little fatter than the drawing says, because I have to seat back pretty far to keep it from jamming on the lands. I don't recall if I ever used this bullet in my Garand or not.

I use the 311299 in mine. 1:8 twist Good accuracy. I've tried 7 different powders. All delivered acceptable results even down to subsonic loads.
