It would have been real easy to to just 'bob' the hammer, but that did.nt really work because of where I wanted the eyepeice of the scope, which puts the power ring ( adjustment ring ) directly above the hammer. So I had to carry that hammer bob a bit further, turned out to be fun. If you look at my photos, you can see where and how I notched the hammer spur, took seconds with a dremel and a grind-stone. I aslo ground a small notch on the front ( chamber side) of the hammer so that the hammer spur would fit lower on the hammer. The barrel release button is now approx 2/3 the size that it was, I cut away at least an 1/8 off the back side, and then changed the conture with a grind-stone, ground off the back edge. Apply your choice of blueing. I now have 3/16" clearance from the top of the hammer to the bottom of the power ring of my scope. By the way, this is also a .25-06, I love that rifle.
