Neck Bushing Die Question

[Jayman_10X]

Good day everyone,

I use Redding Competition Neck Bushing Dies for my 260 Rem bolt action. As I'm sure many can attest, they work great. My Dad owns a 243 Win bolt action and he would like to use Neck sizing dies for it (he currently full-length resizes). I'm wondering if he can purchase the appropriate size Redding bushing(s) and just drop into/use my 260 dies? Obivously that would require a change from my current micrometer settings, but does anyone see any issues with this, or tried it themselves before?

thanks,
Jason

I use the same die for my 308, 260, and 243. Just get bushings for each caliber.

Just so we don't confuse any newbies who might think they need only one neck sizing die for ALL their caliber needs:

The reason this cna work for the 3 calibers mentioned is that 308, 260, and 243 all use the same basic case - they are identical BELOW THE SHOULDER.

A Redding bushing-equipped neck sizing die properly set up does not touch the shoulder, nor size the case walls below the shoulder. It just sizes the neck of the case to the size of the bushing selected.

Since the case walls belwo the shoulder are all identical for the 3 calibers mentioned, the case, and therefore the neck, will be properly centered in the die, so the necks are kept, or are forced, into being concentric.

If a case whose below-the-shoulders walls are smaller in diameter is placed into the die, the die walls will not be able to keep the case proeprly concentric, so the neck can be properly sized but not concentric with the rest of the case.

So it appears from above the 260 Redding bushing neck sizing die (with correct bushings)will work for the other calibers in question.

How about same question but using the Forster bushing bump neck die. In other words, if I have the 308 bushing bump die, can I change the bushing and use it for the 260 to bump shoulders?

Thanks guys, Darin

Someone more knwoledgeable on the 3 calibers needs to answer that question authoritatively, but since the 308 and the 260 use different bullet diameters, the shoulder HAS to be different in some conbiantion of length, angle, and bullet opening size, so I'm going to guess the answer is NO.Put the 2 cases side by side on a table and ask yourself if it is possible to fully control all dimensions of each to its correct dimensions using only the same one die. I gotta think "no".

All 3 cases have the same dimensions up to the datum line. After the datum line the shoulders are progressively longer for the smaller bullets (same angle, just more length to the bend)

If so, if you try to use a 308 die on a 260, the shoulder portion approaching the bullet will NOT get bumped (because there is "air space". not metal, in the 308 die at that point), so the shoulder angle will be distorted AND you won't have proper shoulder-to-chamber contact anymore along 100% of the shoulder area as intended.
