Always with a new gun, whether I've got it second hand or brand spanking new it gets the same treatment. I'll ask the owners recomendations but 9 times out of 10 my idea of deadly accurate and theirs differ. I do it for my old mans guns as well as we both know the guns are spot on then it's just us. Once I've found a batch the guns like I tend to buy loads of that batch to save me having to do it again with another one.

At the end of the day it's one variable reduced, which means one less thing to go wrong and more mental capacity to take the shot. Hunting or competition gun if I get a bigger group than a penny at 55/60 yards then I'll keep trying pellets until I get them, as I'm yet to see a rabbit/rat/corvid with a 1 inch circular head!

It's an easy way to get to know a new gun as well, spending a weekend on the range punching paper and shooting targets. But most guns will do ok groups with most pellets, it all depends on the standards you set of yourself!
