I'm still gonna go out on a limb, and say that whatever neck tension is there, is doing most of the work
.
What work........ making it go bang or producing real accuracy in place of poor accuracy without the crimp?
Your a smart guy for sure, there is no need to debate that...
But lets just concentrate on garden variety reloads then...none of the special stuff we know and love.....
Hee hee hee...........
Just garden variety blasting ammo for typically pistols and revolvers......we would not hand seat bullets with thumb pressure, and use crimp instead of neck tension to hold the bullets in
.
Well, there are several folks who reload black powder cartridges that way for blasting ammo, and some of those actually use the modern equivalent of smokeless bulk powder to do the same thing. And we would not teach a guy new to the bench to thumb seat bullets more or less, and use a crimp to hold them in.
if we could spin the bullets around in the case after seating and crimping, we would address that situation pronto
.
hee hee, I know your point and agree with it. I just don't like blanket type statements...........
Felix has opined that the case neck opens up even before the bullet moves (more in rifle ammo I suspect) and this can sort of be confirmed because say 22-250 once fired brass STILL has the factory crimp on the case mouth, and will often hold a bullet well enough to establish a seating depth for example...this irons out in the the next few loadings.
