Wow - another old thread resurrected!

I have been a huge BB fan for years and it ( BB #20A) is my EDC load in my 2" M60-7. I know many Reloaders that have tried to duplicate it and as of yet none have been successful doing so and staying within the SAAMI limits. I suppose that even if one comes within 75 or 100 fps of the BB loads and stays within Spec's it would be a viable practice load for the BB carry ammo.
