CCI 450 vs CCI BR-4

[ChristianSilver]

Running 6 Dasher, pushing 105 hybrid's using 31.9 gr of Varget and 450's. Load is accurate as hell..
Cant find any 450's but have a chance to get my hands on 7,000 BR-4, will these shoot and perform as well as the 450's do.

I run the 450 also in my 6.5 CM SRP in Lapua brass, 41.8 gr of 4350..

I'm not wanting to have regrets.... but I need primers...

Thanks in advance...

i've used both primers in my 6.5x47L load and found them to be quite similar with respect to both accuracy and velocity.... (note: i do not have a chronograph but working with a ballistics app the numbers seemed to be rather consistent).
