Bought these for my G40 with the intend of using them for subsonic loads and bear loads. They're tumbling out of two KKM barrels and throwing random flyers out of an Alpha Wolf barrel. Have tried several powders, primers and crimp levels to fix this without success. Looks like some of the bullets are undersized in the lot I have. I've e-mailed support about this multiple times and got no response.

These are my go to 10mm Delta Gold Cup bullets

Ive found that the 10mm auto really likes the long bearing surface on these bullets as they stabilize really well and are the most accurate bullets Ive shot from the Delta with a custom national match barrel. Im currently running them at 1000fps with a 1.25" COAL, trying to edge up to 1200 fps for my bear loads.
