I would even start out with 10 loads (without being too anal about microscopic differences - so yes, same brass, same bullet, same powder etc) and clamp the rifle and shoot it to see "what it's doing".
I clamped my 243 (Weatherby VGII) during my barrel break in. It shot 5/8" groups with the "cheapest on the shelf" 80 grain Federal blue box soft points. That told me what the "rifle" was capable of with "junk ammo".
Then I started shooting it with the same stuff. I figured, until "I" could match the clamp in accuracy there wasn't a whole lot of sense fiddling with 1/10's of a grain of powder, primers, seating depth, case weight etc etc.
You can build the perfect round if you horse around enough but if (you) can't shoot well enough to take advantage of all that extra work then is it really worth your time? At least initially...
