Primer question

[QuietMike]

“Ginex” SPP & SRP at capital cartridge.
https://capitalcartridge.com/ginex-small-pistol-primers-brass-cup-5-000ct-shipping-included/
$475 / 5000ct

I was about to order these in SRP, but ive been reading around the internet that they are very hard to seat, that they are oversized, and also have light strike issues.
Has anyone used these before for 223/556
if i have to pay triple price i want them to work out.
