For those who may have missed my review thread on the xcr-m back from this spring when I was all excited about it...the xcr-m was a big disappointment for me.
I am likely one of the guys the original poster references when he mentions lower quality optics (I was running a 2-7x33 leupold) and a less-than-ideal rest (shooting off my trailer, both from a Harris bipod and then using the mag as a monopod on a block of wood).
Shooting 10 round groups from a cold barrel, my experience was severe vertical stringing when including the first two rounds. If these first and second round vertical fliers were discounted, then I would characterize the gun as capable of 1.5 to 2 MOA. If you include the cold bore shots, then it was more like 6 to 8 MOA.
I should add that shooting my remington 700, set up with similar glass, from the same trailer and same rest results in consistant sub MOA.
So anyway...my opinion is that if someone is expecting the xcr-m to shoot like a good bolt gun there is a high probability they are going to be disappointed.
Cheers,
Brobee
