I decided to mixture the load data shown on 6mmBR.com for numerous cartridges, to view how persistently Each and every sort of primer was referenced. I chose 6mmBR.com, for a number of motives:
I've had exceptional benefits Using the Wolf primers, not a single misfire and really good regular deviation velocity figures taking pictures in excess of my Chrony.
The principle dilemma That is still for me is how the primers effects might range between distinct cartridges, bullet weights, and powder loads. It's got always been my impact that small ES/SD correspond to optimized combustion; that may be to mention in the event the primer, cartridge volume (strain mobile), powder charge, have been all optimized to present exceptional combustion for just a presented bullet body weight. It is past question that switching primers can normally increase (lower) ES/SD which has a presented load.
Next, Consider the firing pin dent with your check case. It will be very deep. Again, if the primer is unseated and reseated for the duration of Are living hearth, the dent will distort. Indeed, additional pressure will flatten the dent but simply how much the dent is flattened will rely a lot more on the hardness/thickness of your primer cup than chamber tension. So ... trust in the stated masses inside a trustworthy reloading guide for instance a Speer or Hornady for chamber tension. They tension test all their hundreds and in many cases their max hundreds are never ever increased than SAAMI specs ... in actual fact, they are generally really conservative.
KenK stated: I've generally normally applied CCI primers. I had been just lately offered a carton of 1,000 Federals. I used them up, could explain to no distinction between them and also the CCI.
There weren’t sufficient loads on 6mmBR.com referencing large rifle magnum primers to offer an adequate sample sizing for the comparison. On the other hand, here are some with the magnum primers commonly employed for match grade ammo (no certain order):
It really is perfectly realistic to imagine that federal m215 primers particular person primer was challenging, but The difficulty can nearly always be traced to other causes. Very often, that primer will fire if it is hit once again.
The just one caveat on this is if you turn from a normal to your magnum primer, and it's recommended that you choose to back from the cost.
Increase to quote Only clearly show this consumer #2 · Mar 31, 2012 I've experienced identical issues with Federal .223 brass. I thought it was only a funky lot of brass, but maybe not. Appears to be I don't forget studying that Federal brass is effective finest with Federal primers, and that Federal primers in situations of different manufacture You should not generally give preferred outcomes.
I am pondering if I would like to start out my target hundreds a tiny bit lighter While using the Federal primers and get the job done my way up once more as I'm using the CCI 400 normally.
About three/four of my readily available are CCI, and the majority of the rest are Fed. I happen to be working with LP and SP Fed currently to clear some Room. I may match with a lot of the Fed match LR primers Down the road to determine whenever they tighten groups.
Quick reply: the complete "totally free world" has It is really trousers down beneath it's knees, and also the lesson has long been agonizing.
