BR4 or 450's

[bkmilw]

How many guys shooting the br or Dasher or variant use one of these. Im shootin a dasher and am using the br4 with RL15 but am getting bad E.S. I bought a case of 450's and some REM 7.5 to try, Anyone use these and have some input. THANKS

Use the CCI 450's and your ES will come down. The CCI 450's work much better than the BR-4's or Fed 205's, when using the 105grn bullets.

Ditto what 6br said.

Don't expect anything magic when switching from BR4s to CCI 450s. We did a comparison test with a variety of primers using a 6BR railgun. Accuracy was equivalent, velocity a little higher with 450s. ES with 450s was higher in one 5-shot string, lower in another.

In fairness, we'd really have to do a more comprehensive test,say 60-80 shots) to get definitive results.

Hey E.I.C. ever use the REM 7.5 ? Or have any info? Or anyone else. THANKS

I am using the 7 1/2's due to my local supplier only having them. Shelves are pretty bare.

I did some load testing with my new Lothar Walther Barrel in 6BR last weekend with 105 bergers. With 30gr. of varget and the 7 1/2's had a three shot group of 3/8" at 250 yards. I haven't be able to really wring it out due to the weather around here but they seem to be working. I didn't really like the velocity i got but that is probably more so my Chrony than primers.

I don't know ES or SD numbers as i go by what the target tells me once i can shoot for group at least 400 yards.
