*Pics* - should I expect leading?

    Here's my deal... These are 115 gr. lrn cast with a Lee mold size .356 for 9mm. I have been running these through my 9 without any leading whatsoever (it's a glock furthermore). Every measurement I get off of these say they are dropping at mostly .358 with a very few at .357. I am water dropping them. The pics are of one that I tapped down the barrel of my dan wesson 38/.357 barrel. Can anyone look at these pics and see if they are appropriately sized to be loaded as 38 special rounds? They seem to be fully engaging the rifling as well as the main bore walls. Appreciate all feedback and opinions. Can post more pics or provide more info if need be.

    First, never slug with a hard, water dropped bullet, you'll get some spring back, always use dead soft lead to slug. If they size out at .0358", try them, nothing to really lose.

    According to the 0.357" diameter and the way they look in your pics, they should lead. BUT, in my experience doing similar with 0.357" 125 LFP, they'll probably work great in 38spl. Keep the loads light. Use "Cowboy Action" data to start out with and you will probably get good results without leading. Load them up with a magnum charge of Bullseye and you'll likely have a mess.

    I have bullseye, 231, universal and unique. Would you have a recommendation as to which of these would be the most suitable? None at the lgs so I need to make one of these work. Or should I just hold off till I can get some correctly sized molds? Was just trying to be frugile with the molds I already have.

    Out of the powders you list I would try the WW-231. SJ 40

    My guess is that they all will work well. If they don't shoot with Unique, they probably won't shoot at all. I've only tried my similar bullet with 4.5 Bullseye and they shot lazer beam accurate out of my GP100. Any less than 4.5 and the case wouldn't obturate and I'd get sooty cases.

    Double check my data for safety as I could be mis-remembering it.

    This is double action, off hand, at 25yards

    If they end up leading and are too small you could use a bullet coating, epoxy paint or powder coat. This will add a couple thousandths and not require lube.

    Excuse my ignorance, but can you guys show me what leading looks like? I have shot DT hardcast lead, and cleaned pretty good afterwards, but I'm about to be shooting a lot more lead, honestly of unknown alloy. I'd like to know what I should be looking out for. Stock G20 barrel and tumble lubed boolits.

    You'll see it if it's there. Your shiny Glock bore will look dull. If you look sideways at it from the muzzle, you'll see a dull, light grey, wash/coating on the bore surface. Clean it with regular bore solvent first before checking so you remove any carbon fouling. Then, it should be shiny clean.

    Regular ol' CLP will get rid of any? I'm not going to bother with the gas checks. PITA.

    CLP, #9 etc will not remove leading. If typical solvents like that leave you with the polished, wet, look that Glock bores have, you are not getting leading.

    Grey scaley crap in the barrel. It looks ugly. When you push a patch through it show on the patch and require a lot of scrubbing to get it out.

    Here is something Jack wrote on the subject of leading that may help.

    Oh the memories. :rofl:

    After that visit I realized leading with properly sized and lubed bullets just doesn't happen to any worrisome degree and you can essentially shoot the gun forever with out a worry about lead build up. BUT lube has a lot more fouling potential and it will build up everywhere in the gun. But you can shoot 2-3K rounds in a Glock easily between cleanings. It collects in places that just don't mater.

    That is the key to cast lead bullets and yet there are people worried about shooting them from OEM barrels,when there are more important things to worry about. SJ 40

    If your Glock barrel is leading badly it will Key Hole bullets very quickly. You will know by looking at the target that the barrel is leading up horribly. If the barrel is going to lead badly, it's going to lead and it's going to get worse exponentially faster. Normal leading just leaves a small deposit and doesn't get any worse. Good example I (depending on bullet hardness) get a small ring of leading in the throat. It's very small, never gets worse no matter how much I shoot. Softer bullets don't do it. Harder do. So it will lead that small amount and stabilize at that point. Same in the barrel. It might lead just a little but then it won't get any worse and will likely lead in different parts of the barrel just randomly. At least that has been my experience.

    I am using the following bullets
    http://www.midwayusa.com/product/83...diameter-125-grain-lead-round-nose-box-of-500

    With CCI 500 small pistol primers.
    3.6 grains of titegroup
    and the oal escapes me currently don't have my notebook here at the office.

    I have 400 of them through two Glock 9mms with stock barrels. There seems to be more powder fouling but not even close to the amount of leading that is shown in the photos on the older thread. They are accurate and are making a great training round for me so far.

    Thanks, GMB

    Thanks but that would totally defeat the purpose of what I'm trying to accomplish. I already have a 9mm load that's perfect. What I'm gunning for is a cast boolit that will work in .38 as well as 9. And with over 200 lbs of lead in the shop, can't see myself buying someone else's bullets.
