    Glynn, I have to disagree on the hard boolit statement. IME they work very, very well, especially at long ranges (100+ yards with pistol) IF, and that's a big IF, the gun is properly dimensioned AND the boolits, like you said, FIT. If they don't fit, it doesn't matter how hard they are, leading will still occur. I didn't feel like hard alloy is all that desireable for the downrange application here, and moderate alloys give a bigger "fudge factor", so I DO agree with your recommendation, just not the general statement.

    Actually I have backed off a goodly bit on that crimp. My idea at the time was to round over the case mouth somewhat thinking that it might feed a bit easier. Not using anywhere that severe of a crimp any more.

    This is what it looks like now.... that bevel base bullet loaded bass-akwards.

    I use BAC at 2400 ft./s in 223 Remington without leading problems. Your problem lies elsewhere...

    Hay gear-- not a problem-- you said it better than I dd-- if fit is good hardness not a problem normally -- if fit is so so softer will help- it still comes down to fit-- I have a couple of firends that use Leadheads-- which are reasonable bullets -- but very hard -- one likes them at 950 or1000 and he will tell me he can hear the lead as it falls out when he has to clean his gun-- I never could understand -- but I realize now it is likely fit and hardness- or too hard to at that velocity for the fit---i told him to speed them up a little with his 2400 but if they lead at 950 (he was using blue dot) they will be worse --his six gun is a 629-- so he is and always will be a cast plinker- because of the leading issue -- he is missing a lot

    That looks better! Pictures are worth a thousand words sometimes, we can assume nothing when trying to troubleshoot.

    Depending on your launch device, BAC is good for a bit more than 2200fps.

    I'm sure it probably is, but 2200 is the max I've shot my boolits and I wanted to put out verified data.

    Hmm... softer lead? I cast a lot of round ball for muzzleloading arms so have a fairly good supply of dead soft lead. I'm wondering if casting some of the double ended wadcutters using this buttery soft lead might work? I'm sure that more than just a couple have tried it. Did it work well or just a waste of time? These would be for use only in my Model 52.

    Softer lead might work for gallery loads with next to no crimp and an oversized expander die, part of the problem of too soft is the boolit making it into and out of the case without getting squeezed down too small for the bore.

    +1 for gearnasher. If you decide to try pure Pb, make sure seating doesn't size them down. Don't ask me how I know.

    I'll +1 this for sure.

    For me, there is only one .38 Special 148DELWC load, and that is 2.8 grains of Bullseye. But that's just me. It's been probably twenty years since I've fired a Model 52--and you DO have me a bit on the "envy factor." That is a VERY fun gun to shoot and a fine firearm to boot.

    My experience with wadcutters has been that softer works better than harder. With so much bearing surface, every time I've tried to "harden" the boolit--either by adding lino/mono or water dropping or heat-treating or additions to the alloy--I've sacrificed accuracy and picked up some light to mile leading, no matter what lube I used.

    These days, I just use straight WW and let them air-cool. I run them through my lubesizer and use my homemade lube formula, only lubing one groove, and have no problems. (Tried lubing all three grooves one time and my accuracy went to Hades in a handbasket.)

    I take it you were using the Lyman mold... it's the only one I can think of right off hand that has 3 grooves. I'm using the RCBS version that has 4 smaller grooves. Might have to try just lubing a couple of the grooves and see what happens.

    One more thing to try, ED, and it could be an ejumacashun, is use an inertial-type bullet puller and pull one of your loaded boolits, then carefully mic them. You might be surprised the size they actually are coming back out of the case.
