Guys, I notice this alot and hope ya all could share your observations. While loading rifle shells or spitzers, I will set my COL, lets say to 3.3" for 270Win with Sierra SPBT 130g, for my first round. Just because I am anal, I measure all rounds. I get some wide variations due to the shape of the bullet. Corelokts are the worst. With the 270 example, I measured variations from 3.285" to 3.31". Lets say my max COL is 3.3" as suggested by the manuals, should I set my longest to 3.3" and the rest will be around 2.80"? How do you guys do it?

Reason I ask is when I find a load I like and produces good groups, I want to of course replicate it again. But if I set my first round to the desired length, I am kinda constrained by the quality of that bullet.

Also, for those with alot of experience, what brand do you see have the least amount of variations? For me the Matchking would one I see the least.
