no...don't waste your time with it...When working up loads for hunting does it really matter to get that extra 150-200fps if your personal limits are 400yds and under , seem like I find pretty good load on the lower end of powder charges often or right around max , but I'm not a long range shooter don't really see any benefit to pushing it to the limit. Is there another take on this? Or other reason I'm not aware of pushing faster
