From my perspective, as an owner of two Crowns and an Impact, its a tough choice. The first thing I would say is to forget all the rubbish you hear about the Impact having all these POI issues. First of all, I hear the same thing about the Crown, secondly, given the barrel attachment systems the Impact “should” actually be more robust than the Crown. I personally have never had the issue with any of my Crowns (and I have owned three in total, though I currently only have two) nor with my Impact. FX makes tens of thousands of Impacts each year and they are always sold out. That wouldn’t be happening if they were all basically crap.
The Crown, to me, feels like it should be the better offhand shooter. It simply fits me better and feels more natural. However, in fact, I am every bit as accurate with my Impact, offhand, as I am with my Crowns! My Crown Continuum is really great offhand with the 380mm barrel (I have these in .22 and .25). The 700mm barrel is really rather unwieldy for offhand shooting and I find my 600mm barrel much better. I have often thought that, at least in .22 and .25, that the 500mm barrel might be perfect, but I have never tried one. The Impact, with a 700mm barrel, is a much handier weapon to walk around with. And, it is simply a “machine”. Powerful, huge magazine capacity, incredible adjustability/tunability and, amazing accuracy. My Impact, with both .25 and .30 barrel kits, is the most accurate rifle I have ever fired at 25 and 50 yards, bar none. Here again though, there is a dilemma, as my Crown MK2, with a 700mm .30 cal barrel, is easier to shoot off the bench.
As a few people above have said, the real answer is to get both
Impact, 6 shots, 35 yards!
Crown, 700mm .22 5 shots, 34 yards
