Summer of last year, DoubleUp and I both found the 527 in. 17 Rem. We purchased from the same vendor at the same time. What a great rifle / cartridge it is. It has quickly become one of my top favorites, and has produced accuracy of 3 shots into .240" and shoots often in the. 3's. On top of that, I have only experienced such drop-dead performance in one other cartridge, that being one on the heavier side, a 7mmSTW.
It somewhat bothers me to see CZ have what appears to be such an uncaring attitude when replying to your letters. Maybe I interpreted it wrong.
