In another similar 7 LRM thread yesterday a guy said:
Will be interested to see how the range sessions go.
Not wanting to hijack that thread I am starting this one of my own.
We just finished my own Long Range Rifles, LLC
bolt action gun chambered in 7LRM last Thursday.
I took it to the range this afternoon to get it sighted in at 100 yards.
First I shot a 5/8 inch two shot fouling group.
Then after adjusting my scope ... a 1/2 inch two shot group.
... then a 1/4 inch two shot group.
And finally a 3/8 inch three shot group as I ended up just about where I wanted to be on the 100 yard target target.
Then I backed up to 600 yards and shot a 1.30 inch three shot group. (0.21 moa)
All of the above were the first shots fired and no cleaning was done at all so far.
All from a bench using Caldwell bipod with installed bipod lock
and LRH Rear Shooting Bag.
72 gr H1000
180 gr Berger VLD
OAL of 3.360
Not sure of the velocity as the sun's low angle was messing with my chrono.
This is probably the easiest load work up seesion I've ever had. I just used the load suggested to me by Mike and Aaron Davidson of Gunwerks.
And remember --- DRIVE CAREFULLY
