PMR-30 is amazing

I did the complete upgrade on my new PMR-30. Pretty easy job. Took it to the range and all I can say is WOW. It ate every type of ammo I put through it. It even ran the Hornady 30 gr ballistic tip. I read that this ammo is not recommended. If it feeds without issues is there any other reason this ammo isn’t recommended? And to MCarbo, keep up the great work.
