Hi guys,
Wondering where the line is on this.
So you can neck down families (I guess that's the word?)..... .35 Whelan to .30-06 to .270 Win to 25-06 etc.
Compressing a larger neck down must mean the neck gets thicker and since the die pushes from the outside the extra thickness must resolve on the inside of the neck.
Turning the necks will fix that, but if you don't then can it cause problems seating projectiles because they won't fit?
How fact can you go? Guys do 1 step no problem like .30-06 to .270. But what about a big step down like .35 Whelan to .25-06?
Talking in general here, not specifically about .30-06 just to be clear.
