I took the 25-06 to the range today with some Accubonds. It was the first time in a whilethe wind wasn't blowing 40mph and shifting directions, so I could get a good idea of whatthe load was capableof. The first shot was on target, but with each subsequent shot, the bullet would hit about 1/4 to 1/2"lower. Is this an indicator I need to + or - the powder charge, or is it anybody's guess?
