Unis Ginex primers

[Chelsea Kid, #47400]

Hello the fire,

I was looking at an email from Midsouth  Shooters Supply which I have purchased items from in the past. They advertised sale on primers with no hazemat fee. I started looking and they have a number of different brands, but one caught my eye, Unis Ginex. 5000 for $250. I question things when they seem to be too good to be true so I looked them up at a couple of places. Shooters Forum had a number of posts. The only comment to the negative was they were a little hard to seat, especially in .223 brass. In .38's heavily used they were fine.

My question to the gang is, has anyone in the Cowboy world used them?

 

Thanks in advance.

Yes I have them and I only use them in my pistols even though they go off in my rifles.  But out of caution I limit them to my pistols.

Have gotten mostly positive reports on them.

They say that they are in between Winchester and CCI in hardness, but are apparently reliable.

 

I have been using Magtech primers lately with excellent results.

 

Midsouth is a great outfit to deal with.  For me, they’re just a few minutes away, so I don’t have to deal with hazmat or shipping, but they still offer me a rewards program and email updates.

Don’t use them if you have lightened hammer springs!!!

Not 100% reliable for those. I know firsthand!

I have loaded several thousand of these primers.  I find them very reliable and usually a fair bit cheaper then other primers.

HOWEVER,  I  only use them for 9mm and 45acp. They are too hard for my light spring cowboy guns. (Federal only for cowboy).

I have used a couple of thousand in factory sprung pistols and rifles with no FTF. I like MidSouth also.

In light loads they are a bit under powered. I was getting some inconsistant results.

Shot thousands of them  because all I could buy.

On 1873 I had to increase hammer tension a bit but spring is way lighter than original. 

In 44 Russian which has a thinner rim I had to buy a rcbs shell holder to fit the cartridge a bit better than the lee because primers seat hard enough to deform rim with the lee.

Lee uses same shell holder for 45 colt through to 44-40. 

Rcbs has a shell holder specifically for 44 mag/ Russian. 

Now that federal and cci are becoming available at better than  covid era prices I'm buying them instead .

During the great primer shortage, they ran fine in my factory spring NMV's and Longhunter light hammer springed Marlin 94 with +1 washer.

I used 1000 in 9mm cases could not wait till they were gone.  Very difficult to seat.  The 9mm i was using was unaltered.  Bullett

I got 1000 Large rifle when I couldn't find anything else.  They go bang BUT they are very hard to seat.  I broke one of my Lee bench primers trying to seat them.  They were also very hard to seat using a single stage press.  I would never buy them again.

I have used them in 45 Colt with no issues at all.  Shooting Stock vaqueros and Uberti 1866.  And I had the same reaction when I saw the prices the first time I ordered them.

He tried them in 3 of our rifles & very inconsistent in all 3.  Didnt bother to try them in the pistols.
