Is it considered safe to use published Cheddite CX2000 (209) primer data with NS 688 (209) primers?

No way to know for sure. Not very many people have bothered to send in test loads with Nobels to validate wether the exchange is safe with various powders. It would be with most loadings using Red and Green Dot according to my test results with these two powders.

People subbed primers when I started reloading simply because the powder manufacturers didn't supply pressure data in their booklets or manuals back then. If I recall, Dupont started listing pressures in the early 1970's, Hercules close to same time. Peeps had issues with kabooms loading 23 grains red dot in a AA case from old Mec loader bars because its a loader and if you use a 4 foot cheater bar on the handle to crimp and it lifts your feet off the ground crimping anything will fit in a AA, RXP or any hull. Abusing guns were common, so the bolt blows open with every shot, it helps you pump the gun faster. Cool slamfiring a 1897 winnie, makes alot of noise, but it doesn't do the action any favors in the long run. Today we got Prescision and the guy in Illinois to give us the correct answer, and for 25-50 bucks it's a recommended option unless you want to pinch a penny until Lincoln's nose bleeds or pinch a nickle until the buffalo pee's. Swapping primers in the 9000-9500 psi-lup range probably won't get you in too much trouble, the 10-10500 may. We obsess on things now but a safe, non gun abusing load is preferrable. No one answer available for all loads, no blanket answer is good unless you're talking about getting lucky with the Easy Sisters on a weekend at the drive in theatre, guaranteed, but it was a good idea to get them tested too if you know what I mean. 25 to 50 bucks in testing is better than same cash in gun repairs. Pressures can swing low too, btw. Too mild a primer. In these times, "Best to Test", pick a load, send it for testing and stick with it.

I believe the NS 688 data aligns more closely to the Win 208 data. In my opinion in would be safe to use CX2000 load data with NS 688 primers, but you might not like the result depending on powder/wad because the CX2000 primers are “hotter” than NS 688 primers.

Thanks for the link! Helpful for 12 Gauge, but what about sub gauge data?

According to the title page the info is for Nobel Sport 686 primers which are cooler than 688.

Definitely a good catch! Has anyone seen any data for the NS 688 primers?

I did a lot of research on NS 688 / 209's when they hit the market last year. I have posted on here a few times.
*I emailed DKG and they replied to use the 688/209 with Win209 data.
*I have used the 688's with the manual from the DKG website with no problems and great success.
*DKG also confirmed the NS688 is .244 compared to a Win209 at .243 diameter. As a result, they may be "slightly" difficult to load the first time as the hull primer pocket is widened. You may or may not have problems with other smaller primers falling out if you go back and forth. Given the shortage of US primers, I can't imagine this is a common problem. I use a Sharpie to mark my NS688 hulls as a precaution. Since the only primer I reload is a NS688, I don't have any problems with wider primer pockets.
*I spoke with Alliant bc their is no published Alliant data for the NS688's. Alliant told me you can safely sub any primer if the their original load data shows PSI at 6500-8500 for the original primer listed. Do NOT sub primers if the original data for original primer is over 8500psi.
*Any comments about NobelSport primers having problems in cold weather is bunk. The cold weather issues are for 686's. I shot several thousand of the 688's all winter in the upper midwest with zero malfunctions.
***Check the Reloading page on here. There is a thread at the top for tested loads that includes the data sheets. There is a spreadsheet that you can sort by column including primers. It has about 20 different NS688/209 loads.
I have done everything I indicated above and had no problems after almost two boxes of NS688's with different lot numbers.
NS688/209's are darn good primers.

Thanks for the information. Personally I'd have no issues following the axiom of substituting primers as long as the load doesn't exceed 8,500 psi. I haven't found the need to hotrod shotshell loads for clays.

686's are no longer in production.
If I couldn't find data for the current Cheddite or Noble Sport primers. I would use Federal 209A data. I am not telling anyone else to do that. It's just what I would do. If you're concerned send loads to be tested. One thing a lot of people miss. Is when sending for testing. What you really want to know is the max. You can always reduce the powder charge.

I just sent a message to NobelSport Italia asking if they can recommend as to which 'common to the USA' 209 primers extant reload data (if any) is safe to use with the NS 688 primer, and also asking them if there is one common primer in the USA (including Cheddite CX2000) that the NS 688 most closely duplicates as to it's nominal pressure building characteristics.
Thank you. I can't believe how dumb I can be sometimes. Found the # on my Nobel box of 10000. See attache picture.
