The total momentum transferred to the rifle will always be equal* to the momentum of the bullet as it leaves the muzzle plus the total momentum of the gas and unburnt powder leaving the muzzle. The momentum of the bullet is easy to find - weight of the bullet times velocity. The momentum of the...
95% of the "disagreement" on this topic is explained by the difference between what people mean by "carry while hunting" rather than the difference between a round or no round in the chamber.
For my part, I might have a round chamber if I am carrying in a "ready" position with both hands on...
Closing the loop on this: the issue turned out to be that the lower holder/collar in the FA seating die was gripping the bullet very tightly during seating, causing several simultaneous problems including holding the bullet canted, which caused the bullet to "grip" the seating stem and pull it...
100% agree with this concept.
My only nitpick is to mention that someone else's measurements are irrelevant as long as your only concern is consistency (which is almost always the case in reloading). It's not important what the *true* CBTO or COAL measurements are, unless for some reason...
They do not. The cone in the die is (or certainly should be, anyway) quite a bit steeper than the cone of the bullet near the tip, so the die grips the bullet along a ring a little below the tip itself.
I don't have any evidence for this, but my gut says that MOST of the variance in seating depth (and the resulting COAL) is due to the variance in concentricity when loading. If concentricity is off, then length will be too, regardless of whether you're measuring to the ogive or the tip.

Love all the love for the 7mm-08! 😍
'Tis also my beloved, but I'm not sure it's "bigger" than the 25-06 😅.
6.8 Western or 300 WSM? Availability is pretty good around eastern WA so 🤷🏼♂️
