Standard large primers in a magnum?

[User00040]

I’ve been developing a load for my .300wm but it’s just not going as I’ve been hoping for and have been using federal large rifle magnum gold match primers. I feel they are very tight to seat but have some CCI LRP and also some CCI BR2 LRP and had thought about trying them but as DavyG says is it worth the risk…… not really so will try to pick up a tray of CCI magnum primers to try instead.

Cartridge is .300WM
Powder RS70
Primer wise I have been using federal match LRP magnums but I have some CCI LRP and CCI LRP BR-2 that I use with my .243.
Temperature would be anything from 0 degrees C to possibly 30 degrees C depending on how good the summer or how bad the winter is in central Scotland.

It was just a thought on primers as I have some, I also have a little N550 powder and some N160 powder or maybe I need to look at a different bullet currently been trying with the 200Gr ELD X

Is it a Blaser?

Solution is buy a proper rifle

Guilty as charged . I might just stick with it for now due to the investment in buying it

Give the BR-2's a go. When I had my .375H&H I only ever loaded it with standard primers and I got some decent groups from it. .300 Win Mag isn't really a big capacity cartridge so the primers aren't having to work stupidly hard to light it up.

Exactly. That's my experience too.
Too many armchair theorists on this site!
