If I go and have my AR15 rechambered to .223 Ackley Improved using a standard reamer, will I have any problems with feeding or extraction?
To quote a feller that used to post here it will feed like it had eyes.
Would be shooting 40-55gr. bullets
Since you will be having Bbl's cut you can choose the rate of twist that best suits the projectile you want to use.
Using the same reamer that I used for my Rem 700 in .223, would the AR15 fireformed brass be okay to then use in my bolt gun.
I am going to start a fight with this, but if you have the AR bbl, the 700 bbl, and perhaps your dies cut with the same reamer I would do it.
There would be some reloading exparentation to be done, could I neck size only? How much or how little crimp would I use.
