Just curious to hear from some of you,how many shots you can fire before your accuracy starts to fade away.I am currently shooting a 7mmWSM with a Benchmark barrel,and it is a 1/4 moa the first 6-8 shots,then seems to be around 3/4 moa after that.I use Bore Tech Eliminator to clean the bore with,it works really well.I am also using H1000 powder,which seems to be a little dirtier than some other powders I have used before.Does this seem normal,or are you guy's getting more consistant accuracy before having to clean the barrel?
