Serviços Aventuras Primers?

I may have butchered the spelling, but these guys are selling SPP's for $50/1000, 250/case. I did a trial "checkout" and got $34 added for shipping and hazmat.  The seller is Republic, a name I am not familiar with.
Anyone have experience with these guys?

I've got a couple of boxes in the basement but haven't tried them yet. Once I finish loading 45 I'll switch over and load some 9mm and 38, but that may be a couple of weeks.

FWIW Norma USA has them for $50 with no hazmat or shipping.

I have used the Aventuras Primers in hammer fired pistols, no problem. Striker fired pistols have given me a few misfires with them.

I have had a few misfires with both revolvers and striker fired 9mm. All fired on the second try.
They are now designated for practice/training loads. Bought 3k have 2k left. They seem a little tight going into the primer pockets.
