Thread: Different 22 brand question

So I took my new ( to me ) Hammerli Tac R1 to the range today, together with 4 different brands of ammo.
It loves the CCI subs , win, so do I
However it failed to fire the 3 rounds of the Geco brand I tried
There was primer strikes on the rims, but they didn’t fire.
Has anyone struck this before with that brand ?
Cheers

i have found cci rims to be harder than any other so its a bit of a mystery. never heard of geco though

Some of the geco stuff I found was waxy
And gave issues in customers semi autos
Would light strike due to wax/grease stopping it
From fully seating in chamber then firing pin hits the rim
And seats the case completely which causes the
Light strike
I also ran a few bricks through my smith and
Wesson k22 revolver and it had to be cleaned
More often due to wax build up around the cylinder
And under the ejector plate
Was deadly accurate tho
