I too use Starline--exclusively--for .38 spl loaded to around 875/900 fps. Can't remember whether I went with the +P brass or standard. No problems to note other than some case mouths are getting rough. I am using roll crimp which is probably unnecessary and will be going back to taper crimp. Should reduce working fatigue at the mouth of the case.
