Reloading SAAMI Spec Question

[leviathanxx]

Had a quick question for yall regarding reloading 62gr rmr Hornady bullets. Long story shot all my cases, prior to loading, easily fit into the saami sheridan guage. Unfortunately after seating the bullet it then has a hard time fitting into the guage right around the neck area where the bullet is now seated. Everything shoots fine, however, would like to know if anyone else encounters this issue

Thick neck and tight chamber? This is what neck turning is usually for.

Obviously, you don't actually have an "issue" with your reloads fitting your rifle.. You only have an "issue" with them not easily fitting your gage.

Since the gage has shown itself useless. [As many do] Due to the fact that it is tighter in neck diameter. Than your rifles chamber. Drop it in a drawer, and try and forget, that you wasted your money on it.

ETA ... BTW ... "Reloading SAAMI Spec Question" SAAMI SPECS all include "tolerances". Some are a given dimension [plus or minus] acceptable tolerance. Some are a given dimension [minus] a given tolerance. Dimensions can be within SAAMI SPECs and still not fit/work because of tolerance conflicts. Commonly called a "tolerance stacking" issue. Which is likely what your non issue entails.

Gauges aren't the same as your chamber, thus they are a "guess".... Guess if you listen to someone else above, you will be uselessly turning necks. Guess if you listen to knowledgeable reloaders, the gauge is going to show up in the marketplace.

No, thick neck and tight gauge. Different than a tight chamber, as OP states the ammo works in the rifle. Basically taking a working system and introducing the idea of a problem despite everything (except the gauge) working as designed.

Your firearm should be checked for spec with gauges. Go/no go's are really good. It must not shut on no go, this is the dangerous one. If it doesnt shut on go, you'll have chambering problems with in-spec ammo.

Once this is established, if the case gauge doesnt work, the case gauge is invalid. If the ammo works in the gun, the ammo is in spec and dimensionally safe.

I think people use case gauges to be extra safe, but it really causes some weird confusion instead. Same with 9mm, saami spec of 1.169 basically doesnt fit in anything short of a custom gun.

Ammo checking gauges NOT matching a gun's chamber is a common occurrence.
As long as your ammo fits in the gun properly, it does not matter what an ammo checking gauge tells you.

It's possible that you might have set back the shoulder when seating the bullet.

Check with your calipers the shoulder on a new round and the reload.

You might run the loaded round back into the sizing die just enough to touch the shoulder. Use a bit of lube.

If it is set back the shoulder will be burnished. Check after to see if the bullet is still tight.

Those gauges don't check neck diameter, they check headspace on the datum/shoulder line.

I don't know what happened to 'measuring the diameter of the neck' but for me I want the case neck to expand when releasing the bullet.

Whatever rifle you’re talking about is broken and you should give it to me for proper disposition.

This is just wrong advise.

[TomReloaded]

It's a normal neck that also fits the chamber, i think we're trying to guide the op to ditch that gauge.

The reamer neck diameter is fixed. It's cutting the neck all the same. The depth/location of the shoulder is what is fit and what really needs checking with a gauge.

[divingin]

Is your die set for crimping? Trying to put too much of a crimp on will alter the case either in the neck or just below the shoulder.

Unless you're running high recoil loads, there isn't any need for a crimp. Let the neck tension (unmeasured - you happy, Guff?) hold the bullet.

And I agree - lose the gauge. You won't be shooting out of that anyway.
