Infantry Trophy Team Blackfork from several years ago. I think we are standing on the 600 yard berm after firing the match.
I get back from a long sweaty morning at Panola where I was confirming my AR zeros for Infantry Trophy at the National Matches and trying to pick a bullseye load for my Sierra 80s at 600 yards. I.T. practice was all at 500 and 600 and I walked back and forth twice to double check my old sight settings. Back in town I walk into a shop where I'm known. One of the salesman say" You know, my neighbor, who is a hunter and shooter and a hell of a shot says anyone talking about shooting at 600 yards with open sights is full of BS."
I kind of mulled that over for a minute, then replied, "be sure and tell him that you confronted the guy talking about it, and sure enough, he confessed it WAS bovine-by-product, for sure!"
Probably the best place to leave something like that.
Infantry Trophy 600 yard zero held at up 34, right one, just where it was last year. 500 yard zero is up 27, right one. All with Sierra 77s over 25 grains of Varget. I was kind of on the right side. Might try the Saturday Practice at mechanical zero instead of the right one.
Working bullseye loads I shot five rounds, single load and fire at 600 and them had them mark the hits as a group. I tried four different combos but no happiness yet. Nine-ring sized groups.
A little caution on Highpower rifle shooters. They may be low-down lying dogs but they are armed and they can shoot your ass from 600 yards away with open sights, even in the wind.
