Nickle plated cylinders do not take kindly to porting as it will start to peel from the point where you did the porting
Yep...you have to be very careful to stay away from the inside edges if you're doing an O.S.
The Evolution series however are true ABC so we don't have to worry about that though...
As a matter of fact, I'm working on an O.S. .46AX and a Magnum .52 XLS (they both need new rear bearings ) did some work on both last night...will do some more this evening.
The Magnum .52 XLS is virtually identical internally to the Evolution .52 and except for the bore and stroke dimensions, the same as the .60
