7mmRM thanks the more info. the better[I think] I will more than likely shoot the 75 amax since I got a 8 twist instead of a 7.I'll look at mine today and let you know.
Can't give you the specs off of the top of my head, but PTG's standard grind works out pretty well for everything from the 55 grain ballistic tips, to the 75 grain amax.
MHH,i think I have seen one of your threads where you have a stiller spectre action if I am right how do u like it.I think I will be calling them tomorrow to order one.I just ordered the kreiger barrel from bugholes the other night looks like it will be here on Monday.All this rifle building stuff can get on one's nerves more than the wife lol!!
Yes I do,it is another fella with the same avatar.I really want to say thanks to you fellas for the help.Think you confused me with someone else. It's all good.
I've got a bunch of 700's and a single Savage.
Good luck with your build. Rounding up parts is the annoying part, the rest is gravy.
So going with the .032 fb I should not have to worry about anything I will be using AI mags and use as much as the mag will allow.Also if I try some 80grs. to see if the barrel like's them will this freebore allow for it I know,i know it does in yours I just don't want to mess this up thanks.Mine is a .252" neck with .032" FB.
I and most of the AIs I've built shoot 80grn Bergers and the like. They hammmer.
Good luck with your build, you will enjoy the shit out of a good 223AI.

Built a .223 AI on a Stiller last year, using a Kreiger 8 twist barrel.
I wasn't really worried about freebore, but did want a nice "crush fit" of .223 cases into my new chamber so that they would remain tight against the bolt face for good case forming. Used a PTG reamer and go gauge. I cut the chamber absolutely as tight as the gauge would permit, and was very happy with the results.
Have been fire forming with Winchester brass and 24.0 AA2520 behind the 75 Amax. The rifle shoots well, and I have no desire to try other bullets providing I can still obtain the 75 Amax.
Good luck in your project!
Cheers... Jim
I'm running 80 Berger vld's with this reamer at 3030 out of a 22" barrel. (It's hot but fine)All of the 223AIs I've done feed from AICS mags sans an issue.
As far as FB, its up to you. I spec'ed this reamer long ago to be able to shoot 75/80s yet still touch with 50s. It's worked too well to even consider something else.
Suggest you look at .075-.080Fb. Powder charge load density will be high with heavy bullets and you want to run the cartridge long as long as reasonably possible for several reasons.
