I can't tell much, if any, difference, as to point of impact, with my centerfire rifles but my match barreled .22LR has given me fits.How many of y'all hunt with a slightly fouled barrel or clean? I guess it depends on the rifle, but I'm wondering how much leaving a fouled barrel can affect the barrel in the long run if left for a hunting season.
Does anybody make factory ammo with corrosive primers?I clean up my rifle barrels before I take them to the range to sight it in and after firing it to sight in I leave it alone until the hunting season is over. The reason is if you clean it and then go hunting any oil or solvent left in the barrel can cause the first shot to be a flyer and since the first shot is very important I don't clean until the end of the season. It will not hurt the rifle at all to go even a few months before being cleaned unless you were using ammo with corrosive primers.
