    Springfield 3.8" XDM 9mm Success

    I have been tinkerin with a Lee round nose and my XDM for a couple weeks and I finally am getting somewhere. Using a .357 die, 50/50 lube, 4.0 of unique was leading way too much, accuracy was OK. Well, I "polished" the barrel with JB paste AND switched to 4.0 of WSF and after 34 rounds, the barrel was almost as clean as j-words! The gun has had over 1,000 j-words down her to break it in. Just got thinkin....maybe it wasn't the powder, maybe the polishing??? I will have to try the Unique again to confirm. The alloy was a batch of stick-on ww that included some strange, maybe Japanese, ones, I forget what markings they had, but remember the were harder than other stick-on weights but would cut with a side-cutter. Maybe some extra tin in them??? Anyway those ingots "ring" when I drop them, unlike other soft lead ingots. I will have to try coww also to figure out why I had this recent success. I WAS EXCITED TO SAY THE LEAST, when I looked down the barrel.... now recreate it in mass quantities! My friends ask me why I pi$$ with this.....well if I can get this little 9 to do that again, I can shoot for a fraction of using j-words and have the satisfaction of knowing I got it done...with a little help from the fellas here.
    Take a kid to the range, you'll both be glad you did.

    Might save you some work, but it sounds like you are already doing
    some good work.

    If it was easy, anybody could do it.

    Oh ya Bill, I read your thread... a couple times...otherwise I would still be scrubing the short barrel, actually, I would have probably stuck with j-works for it. After reading about many peoples failures on this cartridge and then your thread, I grabbed a mold and dove into it. First time I slugged a barrel and getting the OAL right before I fired a shot helped my progress also. I am still not sure if the JP paste or the change of powder was the result of the current success or what it was. I just hope a can do it again with a new batch of boolits. Loaded the last 49 from that casting session last night with the WSF (Win Super Field) powder. I originally bought it for boolits in a 10mm but recently bought a Lee manual and saw it listed there.
