I am shooting a Rem. 700 rifle, heavy barrel, .308 with Sierra 168 gr. Match King bullets, 43.5 grains of 4064 powder with Win large rifle (not mag.) primers. MV is 2640 according to chronograph. Rifle groups .4 to .8 at 100 yards shooting 5 shot groups.
Tried rifle at 1,000 yards and noticed that bullet holes are oval rather than round. Any thoughts on what causes this and its effect on accuracy?
