I've had my .257 for a couple of weeks now and it has been easy to tune and more accurate than I expected it to be after spending some time with one in .308 .
I wasn't able to get a tight enough shot string at the velocity I wanted out of the 85 grn NSA slugs , so I settled on the 65 grn tuned to a 6 shot string at avg 1023 fps with an extreme spread of 30 fps . Then used a limbsaver barrel tuner to get 1 inch or less groups . Have done some plinking out to 300 yards with great results , and took my first groundhog with it today @ 277 yards Useing the Aztec 5.5x25 that I robed off my crown . I have a Sidewinder 6x24 to go on it when my adjustable rings get here next week . Also added a DonnyFL Condor adapter and a Shogun , hammer slap is now louder than the muzzle report .
The dime will cover 4 of the 5 completely .
