Rford,
I too noticed those inconsistencies with regards to meters/yards. In talking with Brian he mentioned the ability to shoot at over 100 fpe, don't remember exact figure, non the less very impressive for 350mm barrel. Because it can doesn't mean it will perform well at that speed/energy especially in such a small light platform, as to my thinking anyways.
I'm in for the .25 /long, my thinking is this platform will best serve this caliber for my needs. Interesting times ahead, looking forward to the first wave of delivery.
Cheers
