Have an older tang saftey 270 - has always shot 5 cent piece groups at 100 with factory loads - never reloaded for it. In the newer models have a 17hmr, 6mm, and 308. 17 is a tack driver, have 95gr. BT loaded for 6mm, turns dime size groups at 100. 308 shooting factory loads holds about 3/4 inch at 100. Hope this helps. DM
