6 BRA primer

[savageshooter86]

If you only had BR4 or 450s which one would you try first in the BRA? I am trying to trade for some 400s. I also have Wolf small rifle mag primers. But would have to trade my 450s to get the 400s. Never loaded for this round before or any 6BR for that matter

Guys have used both successfully. Unfortunately, you are gonna have to burn some to find out what shoots best.

If you have the basic powder range perhaps try an abbreviated ladder with the primers of choice for a little side by side comparison.

I shot 450's and they shot ok to good not as consistent as the Federal GM's when the weather gets better I plan to try the 400's. of all the powders I tried H4895 is the best, except if you want to try the 110's and H4350 works great...... jim

 

[savageshooter86]

I will try a ladder test with each primer over the range of powder charges and see if one shows better and also better velocity numbers

It seems preference has followed the reciever in my experience. Try all of them, but in my guns generally they will like 400s and 205s, or they will like br4s and despise anything else. But don't sell yourself short, a ladder with everything you have available will point you straight.

I actually just shot some 450s vs the br4s Today. 25 degrees out, and was kinda suprised to see the same velocity, with br4 having a bit better es. Should I have been surprised?

how did the targets look? Every time on my 284 and 308 comp rifles I can tell difference on paper with one primer really tightening the groups and better ES/SD too

 

[Drolds72]

Es on the br4 was 3, and 7 450’s. Velocity average was 2 FPS difference. Both 5 shot groups. Groups close enough, I have to stretch it out from 100, to 300 or 600. Didn’t feel like laying in snow today!

All I've ever shot were 450's and br4 ....
450's are better imo

Don't forget about the Russian SR mag primers. I don't shoot a BRA but I shoot a Dasher, and the Russian primers have delivered better consistency relative to the 450s. I have limited experience with the BR4. I gave them a look a couple of years ago and didn't see a material difference between the BR4s and the 450s.

Russian primers? We have no chance of getting Russian primers now with Trump gone as president.

I will try them. I have several thousand tula small mag primers

I believe Tula and Wolf are the same thing - different branding of Murom primers. I have a supply of Tula SRMs.

If you don't like them, I'll be happy to dispose of them for you. One at a time . . .

I'm struggling with anxiety as it relates to their availability. I'm down to my last 9 thousand or so.

 

[savageshooter86]

Yes wolf and tula shot well in my palma Brass for my 308

I bought all my Russian wolf primers for $16 per 1k under Obama. They were good but you have to have to hit them very hard.

 

[Baka]

Biden won’t let you have American or Russian primers but hold tight he’s got Chinese primers coming.

Alot of times I see it as what powder you use has an effect on primers. It seems certain powders like a certain primer better. Matt

 

[johara1]

Your right Matt, with RL -15 and cci 450's, H4895 and Fed. GM's seem to work best. Now with Varget .... I'm still looking

 

[Alex Wheeler]

Powder and actions. Certain powders do seem to have a preference. And messing with the ignition can also effect the primer choice.
I think the best way to pick a primer is to shoot groups in and out of the sweet spot. I have been on a primer that would shoot under an inch if you nailed the tune, but either side it got big fast.
