New additions to the GF's household. Will be officially adopted on Xmas.
The Mother is the top left. Howa 20" HB barreled action. Boyds Pepper AT-One stock, piller and accra glass bedded. Warne 20 MOA bedded rail, Badger Ordnance Maximized steel scope rings, lapped. Vortex Viper PST FFP Mrad EBR2c. Knock off Atlas bipod and custom rail mounted with QD sling swivel mount. Gamma 6.5 Muzzle brake. Barrel threading done locally. The sling (not pictured) is an Alien TACS in gray.
Break in for all three was fire one round, clean, repeat 10x, then fire 2 rounds, repeat 5x. First shot is marked and taken at 25 yards then moved out to 100. This was a long tedious venture for all 3, so the last 4 rounds were shot all together at a different target to get a velocity average. These are all round robin groups. Shoot, clean, then next in line. Teething food was Hornady Black 123, then were given a taste of American Eagle 120 OTM, and Horandy American Gunner 123 OTM.
The following is the break in target. First 6 rounds were scope sighters then taped for a 10 round group.
The Eldest Daughter (16) bottom right. Howa 20" HB barreled action. Boyds Blackjack AT-One stock, piller and accra glass bedded. Warne 20 MOA bedded rail, Badger Ordnance Maximized steel scope rings, lapped. Vortex Viper PST FFP Mrad EBR2c. Knock off Atlas bipod and custom rail mounted with QD sling swivel mount. Gamma 6.5 Muzzle brake. Barrel threading done locally. The sling (not pictured) is an Alien TACS in gray.
Little concerned with the scope. Will find out more when we go to longer ranges. First shot was low left. Moved to 100, and the second shot was the high right. I would have been OK with being high, but the way to the right as much as I had to adjust for left is worrisome.
The Youngest Daughter (13) bottom left. From an earlier thread, as far as I know this is the first Howa 6.5 Grendel released into the wild. Howa 20" HB barreled action, accra glass bedded (whole lot of movement on this one). Luth MBA3 stock (really nice, put one on my 16" middy), Houge grip. Warne 20 MOA bedded rail, Badger Ordnance Maximized Alloy scope rings, lapped. Vortex Viper PST FFP Mrad EBR1. Knock off Atlas bipod with QD sling swivel mount. Gamma 6.5 Muzzle brake. Barrel threading done locally. The sling (not pictured) is an Alien TACS in gray.
This barrel seems to be running a little slower than the other two. Will have to keep an eye on her.
All three shot the American Eagle and American Gunner really well. I did not focus too much on accuracy on those since the Magneto speed does a POI shift. All three still printed 1.25 or less groups. The Mother was closer to .5 MOA on the HAG whereas the ELD was closer to 1"+.
Going to be an interesting Xmas morning.
