Normally I use CCI 450 (Mag SRP) and BR-4 for my 6.5 CM. As I was Very Low a friend gave me a box of CCI 41 out of a brick he had just bought. Tried them and found very small difference between the 3. However I did have one failure (out of 60). I received a notice from Brownell that the CCI 41 were back in stock so I ordered a brick. I've used 27 so far - One took 2 tries before igniting, and one I tried 3 time - never fired.
While I wait 2 -> 3 min before opening the chamber, it still leaves me apprehensive. On the range, only effect is on nerves - Because of these failures these will never see the light-of-day deer hunting. Subsequently I have a brick of BR-4 coming Monday.
Not the rifle, as I have NOT had a single failure with older 450's, or BR-4's, or my newly received Fed 210M (LRP). On the failed CCI-41's the indent on the primer looked Normal.
