Primer Question?

[nosler06]

I'm looking for any wisdom from the experience knowledge that's out there. Currently I have switch to 165gr Nosler Partitions in my older 30-06 with H4350 powder. I have been using CCI200 primers and found so articles on the internet about switching primers and being able to tighten groups by as much as half. What are the differences between the Federal 210 primer and the CCI-BR primer? Would this be worth trying or is the expense to test not really worth it? What do you think?

It can be a vast difference, depending on what it prefers. Drop down a couple grains and do another charge weight test. Sometimes it can make things fall right in place.

I don't shoot 30-06, but in my 25-06 I use a magnum primer & found more consistency in both powder burn & as a result much better accuracy.
Fed Gold Match Magnum primers are very good. Brass prep is so important so take good care with it.

Fed 210 is the standard primer unless you are referring to the 210GM match primer which is similar to the CCiBR4 primer. You'd just have to try and see how your rifle responds to the primer switch. Personally, I haven't seen as much difference from one standard primer to another using standard case calibers. Some ball type powders do better with magnum primers and heavier powder charges do well with magnum primers. Having said all this, I don't think it would hurt a thing using the more expensive primers just your wallet

I play with primers last in load development. I have seen tighter or wider groups by switching it up. My two favorites are Fed 210GM and Winchester Large Rifle Magnum. Most of my loads got tighter groups when going from 210GM to WLRM. Build some loads in different primers and see what your gun thinks. 3 to 5 rounds won't be enough to tell you what is good, but it will be enough to tell you what isn't good.

Winchester LR Magnum are like flamethrowers I think they are the hottest just beating out the Federal 215M.

Fed vs CCI is like a Ford vs Chevy fight , everyone had their favorites. Federal is hands down the most used primer by me.
