I don't shoot much W/W brass in my 223AI's,but speculating the chamber dimensions and such,I'd grant 3800-ish fps with a nekked 40 with 29grs of '335.

No secret I shoot 31.0grs with a moly 40,when I launch them. No secret they'll crack the 4K barrier either.

There will be several 223AI's built over the course of this Winter,from guys on my crew,as neither bugholes nor the PACT Pro lie.

One poke is ALL it takes.............
