If they don't work out then there's only so many things that can be changed.
Whether it's the pellets, the brand of primer or powder, the method of swabbing, verifying that there aren't any problems or looseness with the scope, rings or mount, or not sighting it in at a reasonable distance like 50 yards before moving beyond that. And then there's always switching the bullet sabot combination itself since there's so many different ones available, why get stuck using only one of them if it doesn't perform well enough from your rifle?
Which rifle model, primer, scope and anything else that you can tell us about your gun & loads, such what you've tried shooting out of it in the past that led you to select the Lock-N-Loads? How did your old sabots shoot or is this a new rifle?
