Question Primers

I am quite sure at some point this has become a dead horse, however I wasn't around here at that time. That being the case I would pose this question and be thought an idiot rather than blow up a firearm, or worse, :roll: and prove it so.
I stock only Win 209 primers:
I have a boat load of hulls that were primed with CCI 209 primers "20gauge"
I have aprox., 5000 28 gauge of REMINGTON flavor that I believe are primed with Remington primers 209??

So, should I change any of my loading to allow for this?? I have heard CCI primers are a bit hotter, Rem- I don't know. ??

What say the collective Guru's here??

MANY THANKS FOR YOUR INPUT.

All I ever use now or since 1969 reloading shotshells are Win 209. Never saw a hull that couldn't be reloaded safely with them. I do have 2,000 CCI 209s in stock, have no idea where or why I got them, so I guess they'll go to my heirs.

Primers do make a difference in pressure. Check out some of the loading tables. Same charge, same hull, but different primers and see the pressure differences.

Call up the company that makes your gunpowder. I use Alliant powders and their reps have always been able to tell me about safe substitution rules .

If I recall right , I was told that if the load pressure is between 6500 and 8500 psi, it is considered safe to swap primers.

Please call or email your powder mfg. and don’t take my word for it. I’m a little foggy on recollect, so better to trust the experts than a guy on a forum.

The answer to your question ("...should I change any of my loading...") is "maybe" but that decision should be made after conferring with an expert at the powder manufacturer or a search of the literature. The Lyman manual shows 8 different possible loads for 28 gauge Remington hulls with Remington primers, so you should be able to find something that is a validated safe load for that combo with a wad and powder that you may have in stock.

Ditto for your 20 gauge hulls primed with CCI's. There are not a great many loads in the Lyman book for CCI primers in 20 gauge, but I've received the same advice that Badaboom cites from the expert at Alliant - primer swaps are allowable under some circumstances (but this doesn't mean that you should take my word for it - using their website-based inquiry form, tell them what load you propose to use and ask if it's OK or have them suggest a load).

Alliant is one of the better sources of information, by the way. I have asked their advice several times and always received a reasonable and well-written reply within about 24 hours. I have asked the same question of other powder manufacturers in the same way (using their website-based inquiry form) and never received a reply at all. Hey, if you're gonna have an inquiry form on your website, you should answer the queries that it generates. Yes, I'm looking at you Hodgdon Powder...

I, too, keep only Winchester primers on hand. Validate your load with an expert opinion from the powder manufacturer and you should be good to go.
