last week i treated the 257 Creedmoor barrel with DBC just to see if it stays cleaner ? today i shot one 5 shot group after i fired a couple of rounds to dirty the DBC clean barrel . my 5 shot group shot 3085 -3115 fps with 100 grain Nosler partitions group was under 1/2 inch with 4 in same hole .sun was out had a little wind too, this small cartridge shot fast and is accurate with most bullets i have used.would be a great cartridge to be manufactured and also have someone to make better target bullets for a 25 caliber too.
