its been cold and nasty where i live ,i do have a heated shooting house but i do get mirage when its cold . today i shot one 5 shot group with the 25 Creedmoor i used H4831 s.c.with the 131 gr. Black Jack bullets ,i did have mirage kinda bad but manage a 1/2 inch group so maybe that `s the magic powder ? will try H4831 s.c. some more when its nicer outside , maybe this slower powder will help ?
