Do you think that many people would be interested in a tool that would put the military type crimp on primed brass
I have looked for one before, but I have not seen anything that has been manufactured for the general public.
This could be useful for people for proofing loads, brass with loose primer pockets and for people who want to make their loads mil-spec

for me,   no.

by the time the pockets are loose, the brass is hammered.

I know that I have had to pitch quite a few perfectly usable primed 300 AAC Blackout cases simply because the primers were loose.

Some prep'ers might like it. Most reloaders probably not. Maybe post on a prep'er forum and see what they say?

I would think that a dab of super glue would hold a primer in better than a crimp for a prepper who never plans to reload that brass again.

A crimping tool would not appeal to me at all. I want the opposite.

To me, it sounds dangerous.

If your primer pockets are coming loose after one or two firings, your load is way too hot.

Fc  cases primer pockets can be loose after 1-2 firings.

 Not a hot 1st reload either.

I don't see a crimp as a fix for soft brass.

I've seen mention of using a LARGE priming tool to form a circular crimp on SMALL primer cases.  

How useful is a crimp for someone "rolling his own" ammunition?  Not terribly.  Primer crimping is helpful in full auto weapons with high rates of fire.  It was originally set as a standard for US military ammunition because of primers popping in .30 caliber belt fed machine guns.  Since writing contracts is tedious and often error prone, there is (or at least used to be) basically a list of all the MIL-SPECs that bulk-issued GI ammunition has to conform to, and one is crimped primers.  GI M41 .38 Spl had crimped primers...

I'm not saying this isn't a potentially useful tool.  But it would have a very small target audience - and probably need to be built to work on a progressive reloader.

And as others have said, except for the tool Assault Rifler mentions, a tool to tighten primer pockets doesn't seem like a good idea.  Loose primer pockets are generally God's way of telling you that you've overused those cases and it's time to recycle them.

My post was moved but the poll was not.
Prior to it being moved about 40% of the respondents said that they would be interested in a tool like this.
I would say that 40% would be a significant number.

It also has pretty bad reviews and wouldn't really be helpful if you already pressed in a new primer.
After all, it isn't like you can tell before hand which cases have loose primer pockets.

This is an AWESOME tool.  I have both the small and large gauges, and they tell me two things: whether the pocket crimp on GI brass is properly removed, and whether or not the pocket is serviceable.

I have recycled exactly two cases because of unserviceable pockets; one because a previous loader had used a countersink to remove the original crimp (that primer looked BAD when it came out), and one that was just sloppy.  I'd have trashed the first one just by looks, but I needed confirmation that the second one was bad.

That would be a tool with very little appeal.

300 blk is so easily formed from 223 which is cheap to free.

Free or cheap maybe but after processing 1000's it still sucks to have to pitch them because of a loose primer pocket.

I've had LC that was loose after converting without even being fired

I'd consider crimping cases like that for a "one last use" subsonic load. Keep them for when shooting somewhere where brass recovery isn't likely

I've had two minor issues with the tool so far:

1.  sometimes the gage will go in like half way and it's tempting to force it in.  I did this once and got the damn thing stuck and had pry it off using two small wrenches as sort of a pry bar and bent the tool slightly

2. I think the go part of the gage is a bit large.  Had some known crimped primer pockets that I ran through the RCBS military crimp remover and then the RCBS primer pocket uniformer and the go part still went part way in.  So going forward going 1/2 way in is a "go" for me

No doubt...

I actually see no real reason for a crimp period.  The cases are new when they loaded at the factory, so its not like they are going pop out even at 5.56 pressures.

Well, it isn't like you can find factory loaded tracers, AP and API in 300 Blackout, .308 and 30.06.
I actually started only using factory primed brass for my SHTF FAL and RFB .308 magazines and 1919 .308 and 30.06 belts because I was seeing to many popped primers, even loaded at factory pressures/loads.
These mags and belts are loaded ball, ball, tracer, AP and lastly API.

For sure. I bet there is enough demand to make one.

I've actually been looking for one for a few years. I probably wouldn't use it much but would be nice to have just in case.

You do have to avoid forcing the thing, but it has worked very well for me.  If it doesn't come out with a twist, to me the pocket is still too crimped.

No... no I don't think I would be. But kudo's for thinking of it!

I spend a lot of time removing the crimp.  I don't think I want to put a crimp back in just to remove it again.
