Dasher Primer Choice?

[Leaddog]

The CCI 450's seem to be the primer of choice for the 6 Dasher by the majority of posters here.

Is there a reason why folks aren't using the BR-4?

I've used nothing but 205 match primers.

Look what dominates close range.......

I have one lot of Fed. GM match that blew primers in my Panda fire forming, no more.......jim

 

[alf]

I've shot nothing but for the last 6 years.......

Lower ES & SD with 450's over BR's in my testing using Varget.

Alf is a good source, if they work for him try them.

With Varget, 450's with 4895, 400's in my rifle, my sons rifle likes the 205GM w/Varget.

It is situation specific. I've had good results with the 450, BR4, Wolf/Tula KVB-5.56M, 205M and Remington 7½. My only application for the 205M is .222 Remington. I have found that they will not reliably take high pressure. The others will.

,...or when we start turning in cronograph slips with our targets!

That is hilarious.

What powder are you using? If you are using H4895 (2206H) the milder PMC/Tula/Wolf SRM primers are great.

When my Dasher build is finished, I plan to use Varget. I have plenty of the BR-4's and was curious as to why most don't use them.

Use your BR4's, they work fine in my Dasher. I've tried the 450's in several different guns including a 6.5x47, and always seem to come back to the BR4's.

I have better luck with 450's than br4's and have not found a powder to shoot as good as RL-15 in the Dasher.I tried them all and the Dasher will shoot 2-3" groups at 1K that powder and 450's......jim

The PPC crowd use Fed 205's almost exclusively and they start their
loads hot and them work up : I shoot a 6 Dasher out of a sleeved Rem 600
action but before having the firing pin hole bushed and the pin itself reduced
in diameter and reshaped I blanked and cratered every brand of primer, even CCI's.
I generally load 32.XX of Varget, Fed 205's and Lapua 105 Scenars which chrono around
2955 fps and get me SD's of 4-5. I shoot F Class open with this load out to 1000 metres
and the guys in the pits always tell me how well the elevation holds, "waterline" they call it.

cheers,
Chris

I use both CCI 450's and Fed 205M's and can't tell a lot of difference. I have not had either to blank in my BAT. James

Two years ago, I had cataract removed from my right eye. A week later at the range, without glasses on, a Wolf Mag primer popped in my Rem 700 Dasher, blew residue into the same eye. For a few minutes, eye was blurred. I packed up and went home. Eye seems OK now, and I always wear my glasses, but it scared the bejeebers out of me. Went back to CCI 450's with no problems, and gun shoots just as well. I am using the Wolf in another 6BR and they seem OK.

WOW!!! Holy bejeebers, to heck with the title, to heck with all of it, I sure am glad your eyes are okay!! WOW this is a story all in it's self, that is very scary!

After trying the CCI 450 in mine, I went out on a limb today and shot ten shots at 300 yards in a stiff stiff crosswind with both the 450 and a Remington 7 1/2

I had ten shots just inside two inches at 300 with the Rems, the CCIs opened up just over four.

Now...the wind was ridiculous, straight crosswind, very stiff. Over 20.

So the wind might have had plenty of influence on things, but the results with the remingtons make it a neccassity for me to test them further!

 

[Bradley Walker]

Remingtons are very similar to 450s...

In toughness, yes. But, the Remington 7½ is regarded as a bit hotter, only exceeded by the Fed 205. The attached chart shows relative brisance of both large and small rifle primers. The BR4 and 450 are usually considered similar. [br]
I'm about to conduct some tests using Lapua Palma .308 brass with a load developed using Wolf KVB-5.56M, substituting Remington 7½, Federal 205M and CCI 450 primers in the same final series. If the results are significant, I'll post them. Primer performance has been a problem when trying to ignite ~45 grains of N550 in Palma cases.

What is meant by the term "blank"? New one on me.

Thanks
