Like I said earlier, there is no arguing with neck and head shooters. They all think they are extreme marksmen. And the day you hit the range 3x more than me young man, is the day I'm dead. I send in excess of 10,000 rifle rounds a year on the LOW estimate. Some years as much as 50,000. Around the same amount on my handgun range. Been wildcatting rounds since the late 50's or so. Have several rifles that will shoot well inside of an inch at 400 yards. Practice regularly with an old Mod.70 .30-06 at 800 yards even though I won't shoot at live game past 400 for ethical reasons.
You can practice all you want on paper. But that target doesn't have a brain and doesn't decide to flinch right at your trigger break. You can dream all you want about shooting 3x more than me, or several other members of this forum. But I can tell you with complete confidence that it is just a dream.
