Picked a brick up didn’t notice they were magnum. Seen yes and no for 300 blackout? Any thoughts?

It’s fine. Start low and work up.

+1. Some recommend magnum primers with slow burning powders like H110 common in Blackout loads.
I run H110/Win 296 in 300 BLK Supers and use CCI magnum SRPs.
No issues, consistent velocities.
A true "Gun Guy" (or gal) should have familiarity and a modicum of proficiency with most all firearms platforms.
Really starting to think shifting everything over to small magnum rifle and pistol would be in the best interest of minimizing supply line issues like we are facing every few years.
I've stockpiled SRP's for (Standard) Small Rifle and Small Pistol cartridges for that reason.

My rule is target and varmint guns get CCI BR-4 and everything else gets a 450 or 41.

Some load data even calls for Magnum primers.

The price of liberty is, always has been, and always will be blood: The person who is not willing to die for his liberty has already lost it to the first scoundrel who is willing to risk dying to violate that person's liberty! Are you free?
