I have a little bit of experience reloading metallics and was lucky to get 1000 Large Rifle Magnum primers...CCI.
I'm getting ready to load 105gr Bergers in for my 6mm Creedmoor (CZ 600 Range-Cool rifle) and wondering if I can use the magnum primer and if so, any changes to the powder charge?
I will most likely be using 4350.
Any intel reloading for that cartridge is appreciated.

Yes you can. Its no trouble.

I use cci magnum lrp primers in my 6.5 creed.

It uses 0.5-1.0 gr less powder for same velocity as non magnum. Thats the only difference Ive ever noticed. Im using h4350 here also.

Similar experience going from mag to nonmag srp primers

Mag primers are the most difficult to find. Seems a waste to use them in an application where better options are available. That said they will work fine.
