Not quite clones of each other but here's my story --
I just came back from my first range outing with my new rifle. I wanted a new one because the components I use in building my Long Range Rifles, LLC guns
has evolved a little bit. I think the one I use personally should use exactly the same components I am building my customer rifles with. So this one has the LRR action made for me by Stiller with my own LRR logo on it.
I wondered if I'd have to do any load development with this one since it was built with the same reamer and same barrel profile, twist, etc. I have about a hundred rounds left from my previous rifle. That rifle is a real shooter and is for sale
by the way.
After sighting in my scope I fired group #1 into 1/2 inches. My 2nd group was just over an inch and I thought what the heck? Noticed a loosely attached bipod and remembered that I hadn't totally tightened in on. It was slightly loose in my hand, explaining the horizontal dispersion.
Anyway, I tightened it and here's a picture of the 3rd group. It measures a smidge over 3/8 inches for 3 shots at 100 yds. It would superimpose nicely over the first group, the 1/2 inch one. So the point is I can use the same ammo with no load development needed! I am sure I could reload for tighter groups but I'd rather shoot than reload....
