I was just wondering what cartridge you used -- was it the 9X23 or 9X25 necked to 30 caliber? Did you just run a 7.62 Tok reamer in a little further or did you make a special reamer?

9mm Mag brass and ran the Tok reamer in deeper. One pass in std Tok dies and you're done.

Thanks for replying -- I had gotten some 9mm Win. Magnum brass some time back and had played with the idea of maybe having the chamber on that Tok barrel I got from you run a little deeper, thread and seal the existing gas port and go to a pistol length gas system for the longer cartridge. I guess the idea was to make a short version of the 300 blk out. I've been doing really well with the other Tok barrel I have that already has a pistol length gas system and using heavy bullets but then I realize that I got that short gas system barrel from you so I could just shoot commercial or milsurp ammo and I back off on the 9mm Tmag idea. I had been thinking about shooting heavy lead bullets since they would be a heck of a lot cheaper than some of the commercial jacketed bullets I've been shooting. In the past I've used the 115gr lead bullets designed for the M1 Carbine cartridge but I'd been shooting them only in by old blowback tok upper. Some of the people shooting the 300 blk out have also been talking about going to heavy lead bullets since the velocities they talking about seem to fit right in with the maximum velocities for lead bullets. I keep thinking maybe I should just go to a 300 blk out and forget about screwing up my good working Tok carbines.

Good points! Keep the Tok and use it for blasting the surplus stuff. The TMag approaches M1 Carbine velocities but the 1:10 twist is not the ideal. Go with the Blackout those 247 note riders pack a punch!

I have been thinking seriously about doing the 300 blk out. Also been seriously thinking about using lead bullets since the bullets that people have been saying were perfect for the Black Out are special bullets that can get expensive real fast. I don't own a suppressor so most of my shooting would be supersonic but in the velocities that lead can handle. By the way -- there was a picture of some (I believe) 247 bore rider bullets that Gray wuulf posted. The look so perfect that they almost looked machined. Did they come from a mold or were they swaged to that shape? This is the picture:  |

Those are from a Master Caster! Mine don't look like that .... I haven't been able to get my lead and mold hot enough. GW did send me some tho  |

I wish there was a version of that bullet that had a bore rider section that was only about 1/3 or maybe 1/2 the length of the bullets in the picture. I would guess the bullet would run something like 150 to 170gr. I figure it would work better in the normal 1:8 twist of a Black Out barrel -- hell -- if they were that much lighter they would work in my 1:10 twist. I've done 168gr matchkings in my 7.62 tok carbine with the longer pistol gas system but those bullets are just too darn expensive to plink with. Below is a picture of the Barnes TSX 110gr bullets I use on the right and then I saw on a 300 Black Out site that there was a new 110gr TSX as shown on the left. The only difference I can find is an "X" on the base of my first bullets and an "L" on the new bullets that I had to pay extra for -- I got sucked in. Notice the box on the left says the "New" bullet is for the 7.62X40WT and also lists the 300 Whisper and 300 black Out. I guess I was paying extra for the information -- and there's only 50 bullets in the boxes. I drive these bullet at a hair over 1950fps so the little Tok cartridge is no slouch -- with no over-pressure signs. Would be nice to have something similar in a cast bullet!  By the way -- loaded as shown, they fit in an M1 carbine magazine. |

Sounds like the perfect spot for for your basic Linotype gas check!

I wish I had the know-how to make a mold that duplicated that 110gr tsx bullet in the picture -- sure would be a lot cheaper shooting. Those 110gr TSX bullets work really nice out of the Tok brass but I have to use them in an M1 carbine magazine. On the other hand I have a pretty good time with the Hornady 110gr round nosed FMJ bullets -- and they fit in the PPS magazine. I wish the round nosed bullets were soft point or HP's.

I believe that Lee makes a somewhat pointed mold in the 124gr range for the 7.62 x39. Should fit the bill nicely

I went to the Lee site and could not find that bullet but I did find a place that does make Lyman cast 130gr bullets that look like the picture below.  I figure I can buy 100 and if they don't work for me I'm not out that much. |

Check the last Midway sales flyer.
Midway lists a few .311 90-120 gr 1&2 ogive bullets. Didn't see the 124gc I thought I saw in the flyer.
I did, however see the new Lee TL309-230-5R made specifically for the 300 AAC AR. Not yet available tho.....
