Home Forums Hunting & Shooting Gunsmithing Model Seven in 223 to 221 Fireball?

I had that exact hunt built, model 7 223 to 221fb.
It would not feed or eject properly.
Tried Sako extractor, still did not work.
Eventually rebarreled to another cartridge, 6X45.
Have a R 700 that was factory 221 FBI works great
Also had a sako A1 that was a 223 rebarreled to 221 FBI, with no alterations, works great also.
