If you look a the SAAMI spec for the cart it will invariably be different to various manufacturers figures. In my case life is fairly simple as all of my rifles (1 No4 and 3 ARs) are all mag fed, so the best OAL is mag length and then mess with the load for the harmonics.

In some ways you can cheat the effects of variable seating depth (or at least seating into the landes) by crimping, and we would not want a bullet that is being thumped into a chamber via a splined barrel extension to have too long a seat anyway.

Different to hunting I know, but the point is that there are many variable to mess with, so dont worry too much. There is usually a way
Thanks for that. Yes, I'm going to carry on using the SAAMI length. I was just particularly surprised at the very short OAL suggested by Vihtavuori. I'm not going to try it!
