Lately there have been a few threads asking about identifying the new or old MKII and 93 actions. Savage used to make two different receivers/actions. One for the MKII (.22lr or .17hm2) and one for the 93 series guns (.22mag or .17hmr). Sometime in the past year or so Savage started making the "E-Receiver".

When these were finally in the catalog, there was a change made to the barrel shank diameter. Standard barrel shank diameter on standard calibers are 1.055" x 20tpi.

I promised myself I would not interfere anymore in these threads that seemed to have everybody worked up, but now I am going to intervene. It doesn't bother me that you want to tinker and make the world better, however your methods are what got me upset.
