Testing is essential, I agree. The results with one particular rifle could be quite different in another rifle. What runs well in one rifle may or may not achieve similar outcomes in another rifle. For that reason, I am skeptical about predicting results.
I would only agree that “Reloading is the answer,” if that response is qualified by adding that the predictability gap between reloads and today’s premium factory loads seems to be narrowing. Many who reload will take issue with my statement because that’s their thing.
That wasn’t the OP’s question. I recommend taking both types of ammo, the bulk Federal he mentioned and match grade, to the range. In fact, trying different brands of match ammo for comparison will provide him with a base line and perhaps a comfort level to boot.
