I'm hoping they slug at .355 or .356...

I pressed .356" diameter MBC 125 gr RN bullet to .360" diameter to slug the Lone Wolf 40-9 conversion barrel. Groove-to-groove diameter ranged .355"-.356" (my caliper measured factory bullet to .356").

Mucho grassio. Any issues with leading shooting .356 MBC pills?

I use 3.8-4.0 gr W231/HP-38 and 4.0 gr Promo at 1.080"-1.100" OAL and no leading in the rifling of LW G22/G27 conversion barrels.

I do get slight smearing near the chamber end that comes out with a few strokes of old bore brush wrapped with copper scrubber (Chore Boy).

I didn't slug mine as I mostly loaded jacketed bullets, but it took to .357" cast bullets like a duck takes to water. 100 rounds would leave a speck or two of lead, but a quick swipe with all copper Chore Boy took care of that.

I cast two 9mm bullets: 124 grain Truncated Cone and a 124 grain Round Nose. I sized the 124 TCs to .357" for my 357 Sig barrel and leave the RNs as-cast at .358" for my 9mm guns. It turns out seating the .358" bullets swages them down to .357" so in the future I going to lube and load the TCs as-cast also if they too mic at .358".

My current alloy is 92% Lead, 2% Tin and 6% Antimony.

The thing about slugging bores with commercial bullets is you do get a certain amount of "spring back" you don't get with dead soft pure lead. Does that always matter? I don't know. It did to one degree or another with other bores of mine I've slugged.

thanks ku4hx. I'm trying to find a barrel that I can shoot my current batch of .356" MBC pills through. With their current demand it seems unlikely that I'll be able to get any more .358" ones any time soon. Both of my 9mms have .357 bores and the .356 pills lead a bit.

I've shot commercial .356" 9mm bullets with more success than a lot of long term casters want to admit. In fact, my experiences with them have pretty much been all positive. I do get a small amount of leading, but that always comes out easily. What many shooters think is lead is really lubricant mixed with powder residue. Clean that out with a patch dampened with mineral spirits and what's left is lead.

Thing is, it's not like jacketed bullets don't leave metal fouling. They do and it's sometimes not easy to remove.

I'd say try a few and see what happens. after getting the lube and powder residue out you may be pleasantly surprised. Of course if accuracy is not where you want it ... game over.

I load my cast 9mm to approximately 1,150 fps to help with base obturation. For me that's 5.5 grains Power Pistol which is not a max load.

I did try some... and it cleaned up pretty well. But I regularly shoot 300+ rounds at a time and reliability is paramount. I'd like to prevent as much leading as possible. Accuracy seemed okay but I didn't shoot a lot of groups. They are pretty light loads also.

Thanks for the ideas... I'll give it another shot. :cool:
