I am thinking about trying the Cutting Edge 252's in my 338 Lapua. I see on the D59 the STB is moved up slightly to accomodate use of a magazine. I would like to use those. However the D64 has the STB further back and will require single shotting, which I am ok with also if need be. My first choice is the D59 as long as it doesnt use up a bunch of my case capacity. Can anyone tell me the overall length of the D59 or D64? then I can do the math from there and decide what I want to do.
