H&R had a '300-series' of bolt actions . I believe different models may have had different mauser/sako actions. The 340 was sold in the early 80's based on the mauser mark x action. Probably similar to the more current 'Remington' model 798 but I have never compared them head up. Depending upon condition, caliber, wood, etc. I'd say 400-600 is in the ballpark.
