6 x 45 Ackley

[pupsdad]

I have a barrel in my lathe all threaded and ready to chamber, I'm renting a reamer. I was all set on a 6x45 Ackley but I'm thinking what else is out there. I know 6mm TCU but is there other options. It's a 13.5 twist and I have a bunch of old match bullets I'll be shooting. Reamers are getting pricey and I don't see myself ever cutting another so renting seems the way to go but I'm just kind of not inspired by this project.

I did a 6x204 throated for 95gr SMK's. A strain neck up is all it takes. Lots of brass available. It ends up basically being an 6x222 Mag improved. I use off the shelf 204 FL Bushing dies with the appropriate bushing and I went with a 204 R Forster Micro seating died with a with 6mm seating stem, I called Forester and talked to one of the guys in the back, told himwhatc I was trying to do and he said it was doable and sent me the parts. It would be a screamer with the lighter bullets. My barrel is a 1:8.

The 6TCU and 6X45AI are essentially the same thing.

If you are looking for a bit more speed, then I recommend the 6X204 that muleystalker recommended. Not many other options out there for a .223 bolt face 6mm. If you can open up the boltface to accept PPC/ARC cartridges, then 6ARC is a great option. Of course it is designed for heavier bullets, but it would still work with lighter bullets.

Kind of what I thought I would get told I'm going to think some more on this.
