Course its worth your time. Thats what reloading is all about.
Ive done it several times with several types of fact. ammo that gave me at least .5 moa @ 100.
I recently took apart some Federal Gold metal Match 168 SMK,s. The powder "look,d" identical to 4064 and measured an "exact" 42.8 gr. The bullet had (what I consider) deep crimping marks as well. Could it really be 4064 that us loaders can get a hold of off the store selves?.....Probably not........
So...seeing as how I had all the components that Fed used from primers to case,s...crimp etc...and I chrono,d the factory loads.I loaded some up. My version was a bit too fast and didnt pattern well. I simply lighten,d the chrg and am now seeing .5 moa @ 100.
I strongly suggest you use a collet puller though. Your gaurantee,d not to loose any propellant as to get a precise measurment.
Good luck
