.223 12/1 distance
What is the max distance a .223 with a 12/1 twist can shoot accurately ? , preferably 1/2 Moa but under 1 moa if push , I can get regular sub 1/2 moa at 100 meters but the chance to shoot over long distances might be around the corner , and my 6.5 x 55 project is a couple of years away, I'm hoping it will do 4/500 meters but the 500 might be just too far but if someone shoot a .223 with a 12/1 twist longer and with accuracy let me know

If I was working up a load for long distance with a 1:12 twist I would lean toward the 60 gr JLK Low Drag (LD) flat base HP or any decent BTHP in the 55-52 gr range. I don't have Brian Litz's book handy but you might be able to go a touch heavier than you expect.
When I get home I'll check the book.

I've shot the 53gr Amax out to 500yrds in a 12 twist producing 1/2 – 1 moa groups on a regular basis but it really falls off after that It's one of the best projectiles in a 50-60gr range in all categories.
Try off the shelf Hornady Superformance 53gr if you don't hand load.
If you do hand load, try them with CFE223 and Benchmark in the 3200-3300fps range. -
Thanks guy's , I do hand load but try and get powders that are made over here in Europe has there easier to get on a regular basis,

You should be good with any powder that pushes it to good velocities.
FYI – factory off the shelf 53gr Hornady Superformance shoots 3350fps in my 223 T3 lite and 3390fps in my T3 Varmint (both 8 twist)…They group better if pushed a little slower with hand loads then factory in my guns. You'll should be right around 3450 out of a 12 twist 24″ barrel with factory rounds.

Regretibly the Bryan Litz book doesn't have listings for 1:12 twist.
