You and I are lucky to have found a cheap ammo that shoots well in our rifle. each rifle is different.
It could be worse, you know. You might test a lot of ammo and found that your rifle won't perform with anything.
or worse, you find it only shoots well if the ammo is $25 a box.
If you like the CCI SV results, go back to the store and buy another brick or 2 (or more) of the same stuff.
Two reasons: A different lot # might not do as well and we will soon have a year long drought of ammo. Stock up while you can.
I tested another rifle and found that the really cheap ($4.50) Aguila SV did almost as well as the CCI. I intend to go back and buy a couple bricks of it.
