Re: Use 30-06 seating die for .308?
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Winchester 69</div><div class="ubbcode-body">Victor, thanks for following up. As you mentioned, many (most?) don't crimp. With a standard die, the case body won't be held by the die when not crimping. Implies for me that a standard die with the crimping feature will do a substandard job of seating w/o the crimp. Comments? </div></div>
The original poster that started the thread was speaking of seating bullets for a 308 in a 30-06 seating die.
In seating bullets in dies OTHER THAN THE SLIDING BUSHING TYPE like the Redding Competition seater die, the bullet is only supported the last distance equal to the length of the case neck. Before the bullet reaches that point it is being guided through space supported on the sides by the insides of the chamber shaped die. The cartridge case itself is not supported on the sides until the case closes on the inside of the die. The case neck will support the bullet the last length of the case neck. But the entire case isn’t supported by the die until the case is fully inside it. The body of the case will have a few thousandths movement at the base until it is fully into the case. In most sizing dies the base is loose a bit until the case mouth is crimped. Even then in most cases the base of the cartridge case still has some movement. But the percentage of the movement is very small. The only bullet seating dies THAT I KNOW OF that hold everything entirely straight is the Redding Competition seater. Or one made on that design.
Did that answer your question?
