Has anyone used Unis Ginex primers in their .277 WLV loads?  Specifically, using 1680 and TNT 90 grain bullets.

no experience but personally i'd pass on the NATO spec and grab their std small rifle offering
https://www.grafs.com/retail/catalog/product/productId/74066

the NATO spec primers are going to be similar to CCI #41, I've used them before for no particular reason,
they're thicker stronger cups and according to the description on Midway they run hot like a Magnum primer

"Number 41 Mil-spec primers are made to the same specifications of the U.S. Military and reduce the chances of a slam-fire.
While designed for you in Military-style semi-auto rifles, they use the same data as CCI magnum primers."

the 1 review warns of seating issues (thicker cups) and FWIW the reduced volume case 277WLV doesn't need a magnum primer?


and the standard primers are an even better deal, is my math right less than 3 cents each delivered?

I'd stick with the NATO spec primers for same reason I prefer CCI-41s or Wolf SR-Mil.  They withstand high pressure better and have given me lower SDs in MV.  They are magnum primers, which may not be "needed" - but seem to ensure very consistent powder ignition.  But - that is why Baskin Robin's sells 47 flavors of ice-cream.

While mag primers may not always be necessary to ignite a Wolverine, there is a difference that can be shown in chronograph numbers.  The biggest reason, though, is the thicker cup on the primer allows for use at higher pressures without issues.

no argument to the merits of the NATO/Magnum ignition, just wanted make the point that they are more powerful than standard small rifle primers

possible the guy that left the review didn't get his Mil pockets swedged out fully or who knows what,
i think most people that leave reviews are those that always have trouble?

little relevance to this particular situation but my Encore won't light Milsurp 308 plinking rounds,
i think that's where my reluctance to indestructible primer cups comes from

then again watch out that you don't conceal rising pressure signs either [thumb]

do they still make Blue Moon ice cream?
