As I said in the original posting, I am changing the rifle to 7x57 R from the 6.5x53 R. Wanting to do that of course could mean issues with the magazine system and feeding. Early on I made up some dummy 7mm cartridges and tested to see if they would fit and feed. Imagine my joy to find out it would work without major issues. So I didn't need to develop a new mag box. One of the things I did not like about the original Dutch Mannlicher was the trigger bow. To say the least it was BIG. And was not conducive to adding double set triggers. There was lots of room inside the bow but not in back for the set trigger. So I have attached a mock up picture of my modified mag box with double set triggers and a new trigger bow. The space between the front of the new T bow and the back of the mag box allows for access to the cartridge clip release button, so that works nicely IMO.

The design process is one of the more enjoyable parts of any project! smile
