Got to thinking(not good at times!!), why not take an AR15 barrel, send to JES and have it rebored to 35 caliber, then take a 357 Herrett reamer and ream the barrel, or send a bolt with the AR barrel and have Jesse ream the barrel and set headspace. Then you could take 22 nosler brass and open it up to 35 cal, trim and load. You have a 223 rim on the Nosler brass. Use a 6.8spc magazine.
Anyone done this before??
Might have to be one of my next projects!!!
