I had my 88B Safari sidelock made with .450NE barrels with a second set made for it in 375 flanged. I am very smitten with both barrel sets and love the handling of this bespok beauty.

I would love to someday get a Heym box lock on a lighter frame with a 24” barrel set in .375 flanged. Getting a Heym box lock in a 8 1/2 pound double would be a really marvellous shooter and wonderful to carry. As has been stated, they do offer several action sizes.

Give the Heym people a call and discuss the art of the possible.
