Casting Lead Bullets - Excessive Barrel Leading?

Ok, I just recently started casting my own bullets again - after about a 30-year hiatus. I've only molded 9mm 125 gr round nose bullets so far. I'm using new Lee molds and they seem to be working just fine. Also, I use their Lee Liquid Alox for the lubrication. I sized the bullets to .356 as instructed. I finally got the opportunity to shoot them the other week. I had really mixed results unfortunately. The more I shot a particular firearm equaled deminishing accuracy results. I fired them out of 3 firearms (Ruger LC9, Walther P38/P10 and a Hi-Point Firearms 995TS carbine - a great gun for the money and very fun to shoot - BTW!)All 3 of these firearms were really leaded when I finally cleaned them over the weekend - particularly the 995TS. (They DO only recommend jacketed or plated bullets - right there on the gun and the instructions so I was forwarned on that one.) Now I've shot hundreds of commercially available lead bullets through all 3 of these weapons and have had no real noticable barrel leading issues. I think part of the problem is that the lead may be too soft. I purchased about 120 lbs of commercially available Lyman #2 mix. If I remember correctly this formula is toward the lower end of the hardness index. I have a Lee lead hardness testing tool hopefully coming this week. Do you think if I increased the hardness of the alloy that this may help correct the problem? If so do you recommend using tin, antimony and/or a mixure to increase the hardness? At what lead hardness do you suggest that I try to achive? As always, any constructive opinions are greatly appreciated.
