ok, loading up a new batch of 25-06's tonite and since I have no real data in my manual for Accubonds I had to get some data off of reloadersnest. Well, as as I approached max load I looked down in the casing and noticed that the powder was just starting to creep up into the neck at 57 gr of IMR 7828. Now I didnt hear crunching when I seated the bullet, but there is no rattling sound when I shake it. What is a true definition of compressed???
This is pretty obvious. If the powder charge comes up inside the case neck to the point where the bullet has to push some of it down into the case further when youseat it, that's a compressed load.
If you are using a stick powder, the kernels liein such a way that they cannot change their orientation in order to occupy any extra space that may be in the case. On the other hand, flake and ball powders have already done that, so it they come up into the bullet space in the neck, the bullet seating process will really compact the charge.
