Reloading - Remington Bench-rest brass:

A few years ago I got my hands on some Remington .308 Bench Rest brass but I never used it yet. I'm not sure why but they use small primers. Has anyone out there used this brass before? Any hints about this stuff that might save me time at the loading bench will be greatly appreciated.

I have used a lot of Rem.BR brass and it's great stuff!!! The only problem with it is that the small primer will sometimes not ignite the powder well when it's cold. The other thing is the brass has a larger intrenal volume compared to other brass and there fore the velocity suffers. If you use the same load and your getting 2600fps you will drop to around 2400fps. with the same load in BR brass. When I went to the BR brass in my 308VS it droped my groups a .1 to .2 and I also didn't have those "flyers" that you can't figue out where they came from. The other thing you will need to do is get a Redding Bushing die because the brass is so thin the regular die will not size the neck sometimes. As I remember its only .009 to .010 thick it will nearly fit a tight neck rifle. I used 46grs of Varget with the 168s and was then able to reach 2600+fps and the accuracy was as good as my 4895 load only a lot faster. Hope this helps if you need any nore info let me know. I wish they still made it!!!

Kodiak... The Remington .308 brass ".308 Bench Rest brass" was never intended to be shot in a .308... back in the late 70's Remington released the model XP-100 pistol in 7/mmBR Rem, and 6/mm BR Rem...
But for some reason didn't release ammo. They chose to sell a special
brass called .308 "BR" to be used to form these cartridges. It was Remingtons effort to compete with the then overwhelming group of "PPC" cartridges.
The entent was that the .308 BR brass was to be used to make the cases for the new line of Rem "BR" line of guns (I'm sure that a lawer had something to do with it). After 3 or 4 years, Remington decided to come out with the completed cases...
The .308 "BR" brass was never entended to be shot in a .308...
... makes a lot of sense, doesn't it!!!

The idea behind the small primers (in Remington 308 BR) is that it allows the powder to burn more evenly, But, ignition problems can happen.

Bill Wylde,

I have some .308 BR brass which has had the primer pockets "uniformed" with the Whitetail tool. Occasionally I'm getting missfires, and even a second strike won't set it off. Dismantling the cartridge shows an unfired primer.

It always seemed to me the tool removes too much material. I usually set firing pin protrusion to about .052 to .055" in the Rem bolt rifles. Is this enough? What are your thoughts on the matter? Do you use the same depth for both small and large primers?

I know that I'm not going to use it anymore if my protrusion depth is in the normal range.

Are the missfired primers flush with the back of the case head, or recessed 10-20 thou..., and are the primer indents on the missfires normal, or shallow compared to the good rounds that fired?

If the primers are recessed more than about 5 thou, and the primer indents are shallow, the pockets are too deep!
If the primers are flush, and the indents are shallow, the cases have the sholders back too far... too much head space on the cases, not the rifle! Put two or three layers of scotch tape on the case head and close the bolt, you should feel more resitance if the cases are ok for headspace.
Also check the primers... I have about a dozen "fired" missfired primers on a shelf that had no pellets in them.

This particular primer is recessed .008" and the indent is shallow. It just happens occasionally and so I'm probably on the borderline of ignition. But still want to know what is acceptable for protrusion. It could be that the protrusion is too shallow and this case is acceptable; don't know for certain. I know someone else who had misfires at a 600 yd match after he "uniformed" the pockets with the Whitetail tool.

The chamber is a .308 Obermeyer, GO plus .001". Cases are resized to the minimum amount needed for chambering.

Ron N.,

It is doubtful that the uniforming tool is the culprit. It could be off dimension, but doubtful.

You state that you "set" firing pin protrusion. Are you by any chance playing with a homegrown titanium FP? I know these can be a nightmare.

Regardless of the problem, the .055 setting should get the job done, but I'm probably a poor one to ask. The only ignition problems I've experienced were with fast actions and "issue" ammunition with hard primers.

It was mentioned in another post that the cases might be a bit short.
This could be the problem or it could be that something is slowing the striker. You could also have some bad primers, but this doesn't happen often either.

Have you made any modifications to the Remington bolt? If so, you might try reversing these mods.
