The cheddites truly feed greater in my Dillon presses as opposed to winchesters. I don’t know if it’s due to the copper coating slides far better within the stainless feed plate, However they absolutely get the job done improved. I’m gonna be tough pressed to return to winchesters. Ed
And I've never ever experienced a problem about to Get - the bigger/smaller primer grievance. They're exactly the same dimensions.
From what various of us have seen, that cut price primer pierces easity. This causes immediate erosion of the firing pins which causes the challenge of piercing to worsen and that causes far more Firing pin harm.
In addition, triple seven primers are only suitable with distinct slender cord ring weapons, but 209 Load Primers can be employed with any gun no matter cord ring sizing or power stage.
In handgun and rifle I shoot CCI 90% or more, and they may have a background of staying unreliable, although it almost certainly needs to do with weak hammer spring goal guns. I have however to possess a solitary fall short to fireside.
From time to time You must use magnification to see the piercing evidence. Both equally of these primers that you simply see are Cheddites.
I worked with laboratories For several years And that i noticed lots of faults. All good laboratories have stringent QA/QC guidelines which Otherwise strictly adhered to, will mechanically invalidate data. I would want to see Precision's Accredited standards and calibration data for openers.
When you have equipped an incorrect shipping tackle & get in touch with before cargo, we will proper the tackle at no charge. If the purchase continues to be shipped, an address change price for each bundle might be extra. In case you Refuse Shipping, a ten% restocking rate might be utilized.
Though I'd personally get in touch with it a "weak" primer, a CCI 209 (not the 209M) would be an alternative choice, While you'd probably probably really have to raise the powder to help keep the velocity precisely the same a Federal 209A. Federal very producing the normal 209 a long time in the past, but it was a fantastic medium-small electricity primer.
ParachuteAdams mentioned: Nebs reported: What's the profile in the load you now are working with and therefore are considering substituting the Cheddite to the Get primer? It would be useful to understand what the pressure envelope of the present load is. Click to extend...
010" interference . The hull is held down by the rim as being the seating article is pushing up on initially the primer and in the long run The underside area with the hull, therefore the desperation in th head stamp space The seems about .010". Most reloads will observe resistance seating win20s in once fired rem hulls.
Very swift turnaround. And Indeed, it appears that evidently “exterior exams” will clearly show better velocity than “book pace” in spite of The truth that the testers claim their instruments are calibrated to imitate the powder manufacturers exam barrels. I'd additional suggest that he look into the published data over the powder manufacturer websites. That’ll convey to him what his winchester primers in stock 1 oz load will operate. Invest some time on the web and examine the data yourself instead of trust some “online skilled” (which includes myself) to keep in mind and interpret properly. The world is at your fingertips.
" Shotshell loads are notoriously topic to many unintended strain penalties when parts are substituted. As numerous associates have written on this matter, just evaluating a single load to view if primers come up with a pressure variation, and then assuming that every one other Cheddite primer swaps should make exactly the same style of force difference with other load data, is nuts.
