When I had my 300 weatherby I used Large Rifle primers (CCI 200s). I preformed fine. I see no reason to use magnum primers until you step up to magnums larger then the 300's.

Same here, I have loaded large rifle and large magnum rifle and can really tell no difference.

I know people that use nothing but magnum primers in almost everything. You do have to be careful when loading max loads and try to sub a mag primer, they can cause higher pressures. I have used them in my 6mm when short on standard primers. I usually back the load down a couple of tenths and they still shot almost the same velocity.

match primers make a difference in groups. Doesnt matter BR2 of Federal gold, , i think the BR2 works better in slower burning powders though. To be honest , you already have to be doing allot of the accuracy reloading to see the difference match primers make though. But it does work. Also the match primers give more consisnt reading's on the chrony.

As far as i know using mild primer tends to produce tighter groups and less speed difference. One example of this would be PMC or RWS primers which are milder than CCI for example. I am not that experienced in reloading to have 1st hand knowledge of this but i've read quite a lot from "old" guys doing long range shooting and most of them used RWS 5341 (mild LR primer) in their loads.
