7.62x39 small rifle primer loads

All of my manuals and other data I have found are for brass using large rifle primers, and I have several pieces of R-P brass that is made for small rifle primers. What adjustments in powder grains? Thanks

I loaded the same as a large primer and it went boom...No issues.

I use the same load data for both LR and SR with no issues,I only have a few RP X39 cases I picked up at the range,I believe i read the RP switched to LR primer in the new factory X39 ammo so want be an issue for you after you wear that brass out.

As always if you have any concerns about any component change from listed data it's best to work your load up for the starting load,or back you load down 10% from any previous loads you have worked up.
