What is the difference between small base dies and full length dies?

The Small Base Sizer Die sizes the case from the shoulder to the head of the case a couple of thousandths smaller than a Full Length Sizer Die. In certain calibers it also sets the shoulder of the case back a thousandth or two more than the Full Length Sizer Die.

What is an undersized sizing die?

Undersized dies size brass between . 002″ and . 003″ below specifications, so ammunition will feed in chamber in tight chambers. Undersized dies work great for bringing back case tension to hold bullets on cases that may be thinner walled.

What does the sizing die do reloading?

The sizing die provides a means of returning the case to dimensions that will allow the reloaded cartridge to chamber easily the next time it is used. With few exceptions, resizing does not return a case to its original, unfired dimensions.

Should I neck size or full length size?

Neck sizing works the brass less than full length sizing. By neck sizing, you keep from working the body of the case and in some situations may get an extra firing before needing to trim. But eventually you will have to full length size so you can extract the brass without beating on the bolt handle.

Does a full length sizing die bump the shoulder?

Keep your full-length die set up to just bump the shoulder back when they get a little too tight going into the chamber, and you’ll be good to go.” To quantify what Preacher says, for starters, we suggest setting your body die, or full-length sizing die, to have . 0015″ of “bump”.

Is neck sizing necessary?

there are no advantages to neck sizing. Neck sizing used to be popular among target and varmint shooters because it reduced chamber clearance and that extends case life by not over-working the brass. Many shooters also figured that the tighter their loads fit the chamber – the more accurate they’ll shoot.

Can you neck size only with a full length die?

First the differences; with neck sizing dies (whether bushing or conventional) you are only resizing the case neck, and with most setups, not the complete length of the neck. When full length sizing with a properly setup die, you are pushing the shoulder back . 002” to . 003” ideally (some reloaders shoot for only .

What is bullet neck tension?

SAAMI defines neck tension as “The circumferential stress that the case neck exerts on the seated bullet, as a result of the interference fit provided by the case neck inside diameter and the bullet outside diameter.” This is not how any shooter I know defines it, but it hints at what we’re after.

How does a neck sizer work?

Neck sizing works the brass less than full-length sizing, and a bushing neck sizer die works the case necks as little as possible. This results in less work hardening, and more reloads without splits. When you full-length size, the case’s shoulder is pushed back during the process.

Can you neck size with a full length die?

Does a neck sizing die bump the shoulder?

By removing the neck bushing, you can use the Bushing Bump Neck Sizing Die to bump just the case shoulder without changing the neck diameter. This action maintains proper headspace in any chamber, custom or factory setting.

Does neck tension affect accuracy?

Over the years, we have periodically experimented with increasing neck tension to possibly improve accuracy. In testing with machine rests at 300/600 yards, accuracy often deteriorated as neck tension increased; thus, 0.003″ expansion (from sized neck to loaded neck) is where we usually start. Using the .

Is neck sizing better?
