I've utilized BR-2's in 7mm rem mags with results, even in cold temps. But, that was with quite significant situation fill of H1000 and Reloder 26, and Truthfully I prefer to use mag primers, they have not been harmful to obtaining reliable velocities, so it will require absent any be concerned of having ignition difficulties with zero general performance penalties.
SCAMMER Sep 22, 2019 #4 Remember that primer cup hardness isn't the only achievable issue. When there is excessive slop across the firing pin inside the bolt encounter you'll be able to very quickly get primer cratering That may be a Untrue beneficial for pressure symptoms.
Besides the "B" over the primer and more treatment taken when making them they should be equivalent? Also In accordance with cci's web-site they point out the cups are more difficult and work high-quality in semi-autos (just like #34's).
Da ich bisher nur Berdanzündies hatte und die fileür die seven,5x55 irgendwie nur von RWS zu bekommen waren hat sich dort die Frage nach den Herstellern nicht wirklich gestellt.
CCI Primers are continuously tested and improved. Due to this fact, now’s CCI primers are more delicate, simpler to seat, plus more appropriate with progressive and automated loading gear than previously ahead of.

I wouldn't fret above the primer mix. There is not that Substantially force distinction between a Magnum primer and Common. I have experimented with interchanging by way of a load advancement. Mentioned the magnum primers are practically constantly needed for powder prices around 50gr to help keep the shot to shot deviation underneath 20fps.

Ich fange grade erst an Wiederzuladen und habe Magtech noch nie benutzt. Taugen die was oder sollte gentleman lieber die Finger von lassen? 9mm soll geladen werden.
We analyzed loads at both utmost usual pressures and for the starting off hundreds (some labs compute start out masses — we shot them). Normal primers prompted no ignition concerns in the max load but posted better extreme variants in stress and velocity in the decreased force regimes of the start loads.
This could be due to a distinct issue also. Do you use a flashhole deburring Resource and open up up the flash gap an excessive amount of allowing for more strain back again into your primer cup spot? Not a major big difference but federal 215 it does produce a variation depending upon the case and how big you make the flash gap.
