Factory ammo is normally not very consistent especially OAL.So if I consistently keep the same size with all my reloads, under max. I should be fine. I measured a bullet that shoot great out of my rifle from new ones. Also measured a few others new ones also that I have. Most of them were different sizes from each other in the same box. Wow!.. The best ones I shot were the ones that mostly all of them measured the same length. Thanks guys
This. The shape of your bullet matters. You can have issues if you seat it out too far and it’s in contact with the lands.The issue is that when buying bullets from different lots, even though they're supposed to be the exact same bullet, the base to ogive measurement could/will be different.
I just loaded some Nosler .277 130 grain Nosler AB's for my daughter and lot variance was 35 thousandth BTO. *at least they were consistent within the same lot.
That's a ton of difference but it is what it is.
Plan, measure and seat accordingly.
unless you are trying to make them fit in a magazine.....You need to be using a bullet comparator that measures off the ogive of the bullet. Don't measure and try to compare lengths off the tip.
That's how I do it now after lots of years. Magazine and go. mtmuleyunless you are trying to make them fit in a magazine.....
Mickeyelk,I measured a brand new federal premium 270 130 rain bt shell. In the reloader manual it says to load at a certain measurement. But the new shell is smaller. ?
I occasionally get to go shoot with Zeke, and I rarely see him shooting with the same rifle!Load, done, enjoy and then buy another rifle so you have something to look forward to working on! LOL
