Any real accuracy difference between cci400 and cci br4 ???

[Tim Singleton]

I've got several thousand cci 400 and only a few cci BR-4 left. Shooting a 6br for fun local matches.using the BR-4

Is there really that much difference between them?

BR-4's are a little hotter I believe w/ a slightly thicker cup. Ask Wayne (Bozo) He will tell you for sure.
I tried all the CCi's in my Dasher, and ended up using the BR-4's

Very little difference between CCI BR4 and CCI 450. CCI 400 primers are much softer/thinner cups and milder.

The cup thickness on the 400's is .020; on the BR4's it's .025.

When I use to shoot CCI primers I could not distinguish any difference in group size between the two.

However I've been shooting Federal 205 match primers for the past 8 years in my small rifle cartridges.
