Is there a primer that is a substitute for the Cheddite 209, or does it have its own unique characteristics? Hypothetically, if there is a published load in the 6k psi range that calls for a cheddite 209, and you use a CCI209 instead, is it going to matter much pressure wise? Is there a primer substitution list somewhere? I ask because Cheddite primers aren't easy to find locally, but there are tons of CCI's and Win's.

Thanks!

The Cheddite is a lot closer to the Winchester 209 than a CCI 209.

The pressure difference is more dependent on the powder used not the primer.

Usually the faster powders will show less pressure difference than the slower powders, when swapping primers.

With a published chamber pressure of 6,000 PSI I would use the Winchester 209 for that application. The CCI 209 is a bit milder than the Winchester and the Cheddite.

What Mark said ... even Roster has admitted in print that Wins and Chedds will swap straight up .

Sweet! Thanks guys. Just as a general rule then, when would a milder cci209 primer be called for?

CCI209's, IMHO, have always been a very reliable primer in target loads with the typical 12 gauge target powders, including Unique. As the powders get increasing more difficult to ignite I have had better experiences with Winchester 209, CCI209M and Federal 209A primers.

The one exception to that is 800-X. 800-X does not need a hot primer and the CCI209 lights it off perfectly in any temperature. I learned that from Tom Armbrust.

I used CCI209's a whole lot more when they were slightly oversized from all of the other US made primers. They were handy when the primer pockets started to get a bit loose...those days are long gone. I still have about 500 of the CCI's that were actually made by CCI, I use them in my pheasant loads.

Somewhat pertinent, base diameters;

.240 = Rem.

.241 = CCI, Fed,

.242 = Nobel Sport, Win, Wolf,

.243 = Cheddite, Fiocchi,

.244 = Rio.

Looks right Putz ... I think what Mark is referring to is pre Fed CCI's . The newer ones seem to be much smaller as your data sez . I still hear all the old timers saying they used CCI when other primers were loose . (the more things change , the more they stay the same !? NOT !)

16gaDavis is correct.

The CCI 209's in the picture measure 0.243". They have a slight step in the OD. These were made by CCI who were part of Blount Inc. These were made in 1999/2000, I have forgotten which year was the last for these primers, but I am close.

If you look close in the picture you can see the step in the OD of the primer.

And I just scared myself. I only have 300 left, not 500 like I 'thought'!!

Mark , it wouldn't scare me if it was 300 for hunting loads ... targets wouldn't last long !!

Three of my most favorite components are gone for good.

Winchester CF hulls, CCI209 primers (CCI made) and SR7625. I killed a lot of birds with those components. I still have a few CF hulls left. I used up the last of the SR7625 this winter and I am down to 300 CCI 209 primers Crying or Very sad

.

The one I miss most is the SR7625.

I had it explained to me that they make a .410 , 28ga, 20ga, and a 12 ga primer , news to me .

It makes a bit of sense now when ordering what one thinks is the same primer and just a wee bit of difference is noticed.

Ignition rates are all different , most primers brought in are for the 12 ga.

Just when we think things are consistent and cut and dry , one finds out they aren't.
