I reckon It is some thing to complete Along with the metallurgy of the brass? Given the scale, they need to healthy.
This can be straight from Lee's handbook and in addition is repeated over the instruction sheet that includes the Automobile-Primary.
Ah hah! That points out why the Speer handbook, inside the entrance part masking reloading heritage and matters, only talks about CCI and Federal primers like no other models exist!
An additional issue is always to Carefully seat primers to compress the protruding anvil flush with the edges of your primer cup.
Following, Examine the firing pin dent in the check scenario. Will probably be very deep. Again, when the primer is unseated and reseated for the duration of Dwell fire, the dent will distort. Yes, extra tension will flatten the dent but the amount of the dent is flattened will count extra within the hardness/thickness of your primer cup than chamber tension. So ... depend upon the shown masses in a respected reloading manual like a Speer or Hornady for chamber pressure. They force examination all their hundreds and in many cases their max loads are by no means greater than SAAMI specs ... the truth is, they are usually really conservative.
Again for your query. The Federal primers use a different priming compound than CCI and Winchester. It is really my knowing this priming compound is much easier to ignite than CCI and Earn. According to tests it doesn't appear to make any distinction in either precision or firing when there fired.
Many years back, After i 1st commenced using my Dillon RL550B, I used to be obtaining a dilemma seating CCI primers in .forty five acp situations.
Common pistol primers will begin to flatten at about twenty~30k psi, depending on brand name and magnum vs . conventional. Contemplating a 9mm can run as significant as 35k psi for standard masses and nearly 38,five hundred psi for 9mm +P, there is not any question .
Lee will not recomend using federal primers in his hand basic safety primer seater for the reason that he claims they could explode. I have not had a single go off.
I shoot all of them. I have had terrific final results with all of them way too. The CCI cups are the toughest and CCI builds them on the max dimensional specs so they do seat a little more durable than Other people.
Add to estimate Only present this user #84 · Dec 22, 2023 We experienced a lack before the war while in the Ukraine started out. We now have experienced other wars before. This extended shortage along with the exorbitant selling prices on what's out there are a new phenomenon.
Incorporate to quotation Only display this person #five · Dec 2, 2024 I have shot lots of CCI ammo in a number of 9mm guns, never ever a misfire. I do have a pair revolvers that have diminished electric power springs, I have skilled a misfire on at least one of them making use of aside from Federal primers.
Ramped up output for Ukraine likely has not served. I'm undecided how the armed service and civilian markets join.
When you find yourself discussing starting off and mid-amount loads, swapping out elements can be achieved with out Considerably fret. But at higher conclusion hundreds, if you swap out parts you really should really take the time and get the job done the load again buy here up from the start.
