Primer Substitution: 10 Gauge Load
I am loading once fired RST 10 gauge Cheddite hulls. My Winchester primers fit somewhat loose. They don’t back out but I am not assured they won’t. May I substitute Cheddite primers safely. Using 19 grs Red Dot and 11/8 oz shot. Thanks

With 1&1/8 oz and 19.0 grs of Red Dot I use these primers interchangeably. Great results on the clays course.

I don't think there's a problem with pressure but aren't the diameters the same thus not making any difference with fit. I've read somewhere that Cheddite makes two different size primers, one for the USA and one for across the pond - where they're from. I believe BPI sells 10ga Cheddite hulls and you might ask them what's the proper primer. Let us know what you find out.

Cheddite primers are slightly larger than US made primers and can be safely substituted in that load .

I have the same problem with winchester 209 but have been using Nobel sport primers with good luck. JMO. Carvel

Ed,
We discussed primers being spit out of Cheddite hulls used in autos on this thread. Not as much of a concern on doubles. http://parkerguns.org/forums/showthread.php?t=23282 Three solutions: Different primer. Primer Pocket Peener (formerly William's product, now BPI has them) If shells are already made, cheap dollar store fingernail polish around primer after already seated if you fear they will come out. It works and waterproofs. Clear or colors. I used blue for steel loads, red for non-toxic when I reload waterfowl loads. |
this is a good tip e a always knew that finger nail polish was good for something....excuse me ladies...charlie...

Cheddite 209 primers have the same diameter as any American 209 primer. Cheddite hulls, which are made overseas, use a European primer that is slightly larger. At least that is my understanding about sizes of different primers. RIO primers are also largerAfriend at the club thought all those blue RIO hulls laying around were too pretty to leave lay. Then he had to order straight walled hull wads and RIO primers. He went back to Remingtons after a 1000.
|
The Cheddite primers I buy are slightly larger than American 209 primers and fit the Euro hulls better .
|
Then I don't believe you're buying 209 primers.
