Winchester cases and primers. The problem is at 200 yards plus there is no group to speak of. But at 100 all bullet holes touch. I've been struggling with this rifle for over a year now. Look for any and all advise.
A more heavy bullet will resist wind as long as the twist of the barrel is one in nine or below. Was there wind when you were sighting in? I assume the barrel is a bull type based on the length. The 22.250 might be considered an overbore so did you purchase the rifle new? You will have to free float the barrel which means that you will have to run a piece of paper down the barrel to see if clears the stock up the receiver and use a wood rasp to relieve any stock touching the barrel.
Your loads should start at 10% below maximum and work up from there. There are more tricks that you can try if the rifle is new but is it is used, sell it. Please free to contact me if you need to.
