The 2 powders I will be using for laoding my 308 are IMR 4064 and Varget.

The 2 Primers I have and will be using will be CCI BR2 and Fed 210M

I have heard that the BR2s match well with the Varget. Is this true? And which primer would be best to use with the 4064?

Embalmer,
As for ignition, any standard primer will do the job on these two powders. I use the CCI BR#2 because of the consistency of ignition improves accuracy. Good luck.

I use nothing but Remington 9-1/2 primers in my .308 loads, regardless of the powder (and that amounts to around 48 or 49 different powders over the years).

For 308/4064 loads, I've happily used the standard Win LR for about a hundred years but neither the small or large Win rifle primers have worked very well with VarGet for me.

Many of the cutting-edge service rifle shooters are using the VarGet/CCI primer combination in .223 but I haven't needed (yet) to go that route.

I'm with redial on this one: my .308/4064 load is lit quite nicely by regular ol' Winchester WLR primers.

Whatever's on sale.

I shot every primer produced at one time, and would worry about what to shoot for my next project rifle. Then checking my targets (I never throw one away) I noticed my best groups usually came with Federal primers. Now I shoot only 210M and 215M for everything. I do use Rem Bench Rest Match for a buddies Remington 40X 223 when he lets me shoot it. I shoot mostly magnums and like to use the little stuff occasionaly to keep myself honest with trigger pull, etc. Those single hole groups help restore ones confidence the boomers can erode. Good shooting.

I use Varget and Fed 210M primers in my 308 loads and they work great together.

Find a load that is that is relatively accutrate for your specific application. Switch primers. Accuracey should either increase, decrease, or stay the same. Go from there. There are enough variables in the equation (i.e powder charge, bullet weight, OAL) that will keep you off the street and out of the bars for a while.

In my 308 Win:

Varget prefers CCI BR-2 Primers
46.0 w/168 MK
Lapua Case
(Palma Match Load)

IMR 4064/4895 and Reloader 15 prefers Fed GM210M Primers

You guys have got me on this one. I reload for 11 different calibers. In quite a few loads the only variable is the primer. Man, it's hard to see a differentce in group size between them. I
currently use F205 and 210, Rem. 7 1/2 and 9 1/2. I think I could probably switch to CCI and
Winchester and my groups would not change. Now I have heard that some primers and powders don't mix because of chemical composition but have not seen anything to support it.
If anyone has, I wish he would share it with us. Best wishes.
