Unique powder / Speer 115gr CPRN 9mm

0341(4)Life · Apr 21, 2021

Hello all, I'm trying to locate a bit of info on a specific load. I have the latest edition of the Lyman manual and have surfed a few of the boards, But finding any mention of the powder/bullet combo I have has been non existent, any help in the right direction would be Greatly appreciated. I'm new to this but I do my research and err on the side of caution as its the smart thing to do. But I'm at a loss.

I use Lyman data for 115 JHP, but a longer oal to compensate for the longer bullet.
Speer has online data for the 115 TMJ that is quite different than the chart above.

Speer would probably be okay with you using their regular 115 grain load data.

The key to loading 9mm safely is knowing your seating depth and how it compares to the seating depth in your data.
My Lyman manual uses a 115 XTP which is .540" long at 1.090" oal for a seating depth of .550".
As long as the base of your bullet is close to that, you can use the data.

That right there.

Generically, I use would use any starting data for a 115grn FMJ or cast RN of similar profile... with the understanding that the cast loads would likely be a little lower... and work into the data. I have done so. Unique is a pretty forgiving powder... except... in small, high-pressure rounds like the 9mm. If you work up in a reasonable manner, it will show you when you are nearing the Edge.

Start 5.4 grs. Maximum is 6 grs. Of Unique. Alliant data.

Thank you everyone. Finally got back to my puter and was able to read the responses. I am going to load up a few with the data you guys provided and run them through the chrono. Again Thanks much.

I get best accuracy at 5.2gr.. To finish off the ladder, I got one round of 6gr. out, and it showed very clear pressure signs, I stopped there.
