Drew I ended up sending the AI barrel back... wasn't what I was looking for and I ended up just going with a vanilla 243.

I went and shot some milk jugs at 435 to see if they'd stabilize that far. Both the Retumbo and H4350 loads did just fine... I'm done worrying about 100 yard groups. It's not a custom barrel and I'm not a good enough shooter to blame anything on powders, barrels, or bullets.

Now, to chrony whichever I go with, and move on out. My dope from QL got me in the ballpark to shoot out to 435, but I'm gonna want to know what I'm running to air it out I think.
