I have shot thousands of their pistol primers , they are soft not hard like some say... Always went bang... The only problem I have run into is in .38 spl were there's not much powder in the case and they don't burn all the powder.. Changing to any American primer stops this problem.... In 9 mm etc they work fine just not as hot as a Fed , CCI or Winchester primer and it can be seen on a crono... If you can catch them on sale for $19.99 a thousand they are definitely worth a try...
There are some test that have been published on this site that showed very low ES/SD with them in rifle calibers...
