I have a new 24/7 pro LS in 40 S&W and almost every last round in
mag nose-dives into the top of the chamber. I'm loading 175gr. SWC
over 4.0-4.3gr. W-231, OAL 1,120-24. Can anyone see any particular
problems with this load and might this be the possible cause of my
problem? I have some clays in the shop & thinking of loading some up
to try. Will I see any difference? Thank for any help.

Do you have the same problem with jacketed bullets? I haven't loaded any lead bullets in my .40's and most likely wont, but if you hang on there are guys in here that have and will give you info that will help. If only the last round does it, seems strange. I like to follow up on these to learn myself.

Try messing with the overall length since you are using a different style of bullet than a normal FMJ bullet. It almost sounds like you need to go a little longer. Mark

Semi-Wadcutters often cause this problem. Try Flatpoints (truncated cone) or regular Round Nosed Bullets instead.

I would say jwc is 100% correct, I've never loaded them but it did seem to me they would be a problem in the .40.

I shoot 40cal with 4gr. Bullseye and 180gr. Laser-cast. Gun shoots very accurate and cycles perfectly, this after much trial and error.

I don't load .40 cal. but is this a light load? I loaded a batch of .45 acp once to lightly and had a similar problem. :???:
Roscoe45's load with Bullseye would seem to be a hotter load.
