I bought a Tikka T3 in 223. I measured the throat and want to load 75 Amax out near the throat. It wouldn't be difficult to do. Only problem is that the spacer in the magazine forces me to keep them a lot shorter than I want. Any one ever taken apart one of these mags? I am thinking if it came apart (and reassembled) easily enough I would shorten the spacer. Any suggestions/ideas on what to do? I would just single feed but the DBM design makes that rather iffy.
