I loaded some 9mm 115gr. extreme plated rn bullets. with w231 powder, the cases will not eject very well. I have ruger sr9, and a glock26. the rounds shoot in the 26 very well. the ruger will not eject the cases very well. I loaded the bullets with 4.5 gr. of w231. oal 1.100. this is from hornady book. it acts a light load to me. I know the ruger could have a stronger spring than the glock. any information would be appreciated. scooter-2
