Still, it seems an odd practice to send me a sheet that says, 'here's your 1+
MOA rifle, this is your warranty, regardless that you thought you were getting a sub-MOA gun'. It is very disconcerting to a rifle noob like me.
I think you have every reason to feel disconcerted. What if the rifle was packed with a target that showed a five inch group? Would this be cause for concern on the part of the buyer? Would me. And, if all the test target was made to convey is that the rifle "functions", why bother to even use sights? Just shoot the rifle a few times at a blank sheet of paper at the range of a foot or so, just to prove to the customer that the firearm actually "works".
I do agree with others that experimenting with different loads should produce a "winner" in terms of moa, or less (better) accuracy. No reason to "panic" at this point in time.
