It's my first Chorny on my 6.5 Grendel. Weather 58 deg. F., wind 7 to 9 mpg, and sunny. I was shooting north and wind was coming from the N NE. It opened the groups up a litte.
My reload data :
Case Lapua (new case)
Primer Wolf SRM
Powder Varget 28.5 gr. Hodgdon
Bullet 123 gr. A-max Hornady
COL 2.260 of an inch
Crimp Light
My Chorny data :
Ten Shot String
Max fps 2493.56
Low fps 2475.69
Ave. fps 2482.84
Spread 19.87 fps
Std. Dev. 7.5
Group size
Two 5 shot groups
Group 1 1.225 MOA
Group 2 0.785 MOA
Not bad for a windy day.
This was a max load, the reloading data was from US Army, Radford Arsenal, Radford Va. 24143.
My 6.5 Grendel AR has a 24" SS free floated barrel with a 1 in 7.5 twist and a PRI adjustable gass block, Shrewd muzzel brake, Mcfarland bolt gas rings, Tubb's carrier weight system, and Tubb's flat-wire buffer spring. The Upper is a DPMS high rider competition upper receiver. It has a AR15 lower with a Jewell trigger and rifle stock.
