I have the 6.5BA, it is a tack driver, my own loads 140 ELD M, consistent 5 shot 0.25 MOA at 100, the only rifle that I could not finsh a load work-up at 100 yards, shot too good, had to move to 200yd to see a difference. I have had light strikes, was common with the early Axiom, they replaced my striker group, haven't been back out to see if the problem is gone. The plastic magpul mags need to be sanded slightly to get perfect feeding, I haven't tried metal ones. I never sanded my magpul mags, failed to feed once on a while.
I'm not sure how it is a "dumb down axiom", it appears from all apsects to be identical to the advertised Axiom.
The question is how much accuracy vs cost you want. My Tikka 6.5 CTR is a solid 5 shot 1/2 MOA rifle, at less than 1/3 the price of the MPA. I bought the Tikka after my MPA, so in hind sight, I likely would have not bought the MPA, the Tikka is good enough for my purposes.
