I just got a Cooper 6.5 x 284 and love it. Wish I could say the same about my Dakota 280 ack. (see my thread), and I just received and immediatly shipped back my Red Hawk rifles in 280 ack due to poor craftsmanship. Wish I would have bought the 280 ack in a Cooper and/or HS Precision. Good luck to ya and please post your load info and results.
