If you don't spend much time hunting, you won't lose much brass.
A. Here in CO we are allowed to shoot one deer a year, if you are lucky enough to draw a tag. If you shoot once or twice, that is whopping $2 to shoot a deer.
B. Lapua brass seems to last forever. I have lost count how many times I have loaded my current batch.
Here is a pic of a 22-250 case compared to a Creed. I personally think the Creed case is superior, requires no prep, is properly stamped, and is cheap. Still not seeing how necking up 22-250 brass makes more sense.
