Ackley 7mm mag - looking for some informaiton!!!

[cmapga]

I recently received a Ackley 7mm mag with a Mauser action that shoots a Norma 7X61 S&H cartridge from a 28" douglas barrel with a 1:14 twist from my father. This gun was a custom wildcat which was made for him from a gun smith who was a follower of Ackley and understand he spent some time with him. This gun was made in the late 60's/ early 70's. I have just started shooting with it and can't find a lot of information about it on the internet.

Has anyone every had experience with an Ackley 7mm mag or heard of such a setup?

Thanks for your help in advance!!!!
