I just purchased the Rainier 165gr FP plated bullets to load for my 40 S&W Glock 23. I am looking for loading data for use with IMR 700X powder. I also plan to use Titegroup powder.

Try the website:

I've not tried 700x but have used 800x.

I have gone to imr's website but it does not list the particular load a want.

Titegroup From 5.0 grains to 5.4 grains
Winchester WSP Primer

As for 700X, you would be better off with 800X.

Mike, just use the loads for the 180gr & work up.
