[QUOTE="brianwinzor, post: 160137, member: 1067"] I have not used a 22/6mm but know some who do, and most of them use Re22 with the 75 Amax. I believe that with the Sierra 65 grain GK you could start at about 44 grains and work up with either Re 22, IMR 7828sc, Viht N560, H4831sc, or any other powder of similar burning rate. With these powders you should end up with close to a 100% load density at maximum pressure. As a further guide for starting loads with the 65 grain GK, in my 22/250AI,(49.0 grains cap.) maximum loads with this bullet were 43.0 grains IMR 4831, 44.5 grains Viht N560, and Win WXR, and 45.0 grains Re22. With the Nosler 55 grain BT, I estimate that you could start at about 43 grains and work up with powders such as IMR 4831, Re19, or any other powder of similar burning rate. The slightly faster burning H4350 would also be a good choice, but with this powder start working up from 41 grains. The case capacity of the 22/6mm would be very close to a 220 Swift AI (55.4 grains) that I previously used. It would also be close to that of the 257 Roberts case necked to .224 (57.0 grains) that I then fireform to the .224 Clark. Good luck with your project. Brian. [/QUOTE]
