Primers for 7mm mag

[mackillan]

What primers are advised for the following calibers?
a) 7mm rem mag
b) 7mm weatherby mag
c) 257 weatherby mag

I use fed mag primers for all my magnums, and use fed GMM large and small for everything else if I can get them.

I do not think you can go too wrong with Fed primers

Ive had lots of trouble finding federal primers so due to availability I'm just using CCI primers now. No use building loads with components I cant find when needed.

That being said, I have a box of federal 210m I'm saving for a special occasion.

Didnt want to waste them on loading varmit loads.

CCI 250's or Rem 9 1/2M's will work just fine.

I use federal large magnum primers in my .300wm

I use federal, CCI and winchester all magnum!

I have always perferred Federals- BUT they come in waves- sometimes very hard to get. If you are just starting load development save the grief and go with CCIs as they seem to always have stock.

Primers

I use CCI 250 Magnum Primers for my 7MM Ruger and they have been just fine.

I use primers that produce the best consistancy in my loads.
Some rifles like CCI's others like Winchester's.(dropped Fereal as mentioned above)

It all boils down to load development, and range time.
