Redding Type S Full Length Sizing Die

[royta]

Are there any negatives to the Type S Full Length Sizing Die? This is for a .22-250 with a Pac-Nor Super Match barrel that will be used for varmints, predators, and a little bit of paper punching. I will set up the die with the Redding Competion Shell Holders so that the shoulder of the case is bumped back just enough for easy chambering of the loaded round. This die will be used in conjuction with the Competition Seater Die.

My original idea was to go with the Competition Neck Sizing Die, but I feel that barely bumping the shoulder back on every loaded round is a better choice for this particular rifle.

I've read some folks are getting concentricity issues with the Type S, but that might be with the Neck Sizing die, not the Full Length Sizing Die.

I was thinking of going with the exact same setup for my 30-06 which will be used only for hunting.

Thanks for the advice.

Neck bushing dies

Been using them for years, along with the micrometer benchrest seaters. No problems, the only kind I will buy.

There's no down side to bumping the shoulder back each time with a Full Length sizing die. Just don't overdue it. I try to move my shoulders back .001" to .0015". Some shooters try for .0005" but I find that a little hard to measure.

Assuming you are not using your reloads in different chambers, I am curious as to why you full length size at all. How in the world would you measure a
.0005" change in shoulder "bump" ? I am new to the accuracy game. I only neck size, but I am still in the .3 to .5" group arena, so obviously I have a lot to learn.

If you have a custom chamber that's pretty near minimum you won't be overworking your cases by FL sizing them. I've given up on neck sizing and FL size the cases for all my rifles. There's no advantage to neck sizing unless your chamber is so oversized that you get premature head separations from FL sizing. Shoulder bumping 0.001"-0.002" with FL sizing will ensure easy chambering, and won't hurt case life.

It's also likely to improve accuracy. The idea that neck sizing will give improved accuracy because the body of the case will fit the chamber better sounds good in theory, but works less well in practice. The only factory varmint rifle I've got now is a .222 that gives best accuracy with FL sized cases. The others with custom chambers don't seem to care one way or the other. BUT I never have to worry that I should have FL sized the cases for easy chambering, but forgot so they're too tight. Not fun out in a prairie dog town.

I use Redding bushing FL dies for those rifles btw. If your case necks aren't turned or aren't uniform in thickness you might need to use an expander button and Redding's carbide expanders float on the decapping stem and seem less likely to cause the necks to be non-concentric with the bodies.

I took some measurements of the necks of some factory 30-06 ammo and some of the fired brass. The factory ammo necks measure between .3330 and .3345, depending on manufacturer. The fired case neck measures between .3415 and .3420. That's a .009 difference, before adding in the tension necessary to hold the bullet. We're talking up to a .012 difference between fired case and bushing size. This sizing is probably too large to use a bushing sizing die. I think it's going to introduce some issues on the necks. This is as per Redding. I think I'll be forced to use a regular FL die for my 30-06. OK, Forster or Redding for the generic FL die? Probably no point in spending the $$ on the Forster Ultra seater die, so I'm wondering if the Forster BR seater would be just fine.

I did the same thing with my .22-250. It is a Pac-Nor barrel, and the chamber is a little tighter than the factory Ruger barrel. Factory ammo necks measured between .2505 and .2515. Fired case necks measured .2540. That's a .003 difference, and up to a .006 difference overall. I think I'll be able to use the bushing die, and since the targets are much smaller, I should also benefit from the Ultra seater die.

What do you think?
