Those are a plane base no gas check, actually they have quite a few imperfections. I purchased a bunch in a deal. Sized and lubed they did not shoot well at all. Don't have any way to test hardness but they are soft.

My coating process is a little different, used an adhesive on the bullets and dipped them in the powder ans put them nose first in holes I drilled in a metal lid. I made a post on the whole process. As far as PC in throat, no chips just a whitish residue couple passes of brush and gone. Possible effect from the 2400 it burns kind of grey. Before coating this load literally melted some lead to the neck of the case. I plan on test 30-30 also, have both contender barrel and some lever actions.
I know we have not yet reached a conclusion, but are we likely to find that PC jacketing altogether eliminates the need to harden up alloys with WW's, adding antimony, etc.? That would be kind of a big deal given the increasing problem of finding cheap buckets of WW's at the old tire store.
This was one reason I choose these bullets because they were cast with such soft alloy and not up to rifle speed
The use of soft lead instead of WW is the main reason I continue to pursue PC. Yes, the lack of leading is a bonus, but if it was the only reason I would give up the quest. PCing boolits is time consuming. The use of softer alloys would justify it for me.
Interesting. Shot the 40SW this morning. 175 TC & SWC midrange load, 1% Cu toughened 50/50 COWW/ Pb. LLA lube, kept 2" for the SWC, 1" for TC, 50 rnds both. Leaded pretty bad but still as accurate as I can get. 100 rnds PC 165 TC sulfur toughened 50/50. 2" @ 7 yds, through a bbl leaded all the way. I did notice that the first 2 PC shots were next to each other horizontally, the entire group was left of center. I like the PC. I need to cut both with 50% Pb for pistol and shoot before I lead the bbl. Have a bunch of PB 30-30 I need to clean and PC. xyankeeworkshop - not sure the PC will allow getting to 2400 fps with pure, 10 twist, no GC, but it would be nice.Quote:

Sure would like to see what PC would do for .224 with a 1-9 twist.
Some times you just have to be patient and wait till spring for your answers.:)
I powder coated some more boolits today. The BHN was 15 before coating and 8 after coating so it does negate the effects of water quenching. It did not seem to matter when I shot some pc boolits a week or so ago as I had no leading in my 41mag at 1,300 fps or my 30-06 at 1,600 fps.
One thing that made me slap my forehead was the fact I was filing the pc that built up on the base of the boolit at the wires of the 1/4" screen. After doing about 10 of them I just turned the boolit over and sent it nose first into my RCBS LAM I. Sized with no issues and most of the buildup is gone.
I need to get a few more of the Lee push thru sizers in different sizes.
I sized 2 of the Lee 200gr SWCs at a time with the Lee sizer. Cuts down on the hand movements.
I think the 1/4" screen with the squares expanded with a tapered punch works great if you don't mind the nose not completely covered. I am going to work on a piece of the screen to put on the bases when the boolits are nose down for the ground.
Popper, this adhesive is actually a stampin up product my wife has, its in a stamp pad which is transfered to paper with a rubber stamp then a powder similar is sprinkled on the paper and melted with a heat gun, gives an embossed look. I roll the bullets on the pad to leave a sticky coating similar to that of contact adhesive. Then I pick them up with tiny needle nose pliars and run them through the PC and tap off excess. I used the bottle of PC purchased from HF. I baked them at 300 degrees for 20 min. Coating sticks just as good with no spraying. Collecting various partial cans of adhesive from buddies to try and duplicate this process with a spray on adhesive. Might not look as pretty but I'm convinced it has same results for this application
I picked up some powder from hf and am trying some with the heat and dip method. first one was too thick second one much better. Do the guns get better, more even coats?
leadman - AC WD'd WW reduces BHN, try the Cu toughened alloy which rehardens in 24 hrs. cylinderman - found a DIY formula, lanolin or Vaseline/veg oil or glycerin thinned with alcohol. Have no idea if it cooks off or does what to the PC after cooking. I tried dipping and sprinkling with 150F CBs, coating wasn't good, very uneven.
How about a youtube video from any of you guys who have gotten a decent PC routine down? I'd love to see the operation!
Put bullets in 1/4" screen to powder coat, did not work that well. Will load and shoot them tomorrow .
Wow, that looks way better than my effort trying base first on a sheet. I'd settle for that :) For sub 100 yards I'd be surprised if the imperfections on the nose have a large effect on accuracy. Can't wait for the range report.

Couldn't find any high temp conductive epoxy so I enlarged the slots, grind the head sides off, insert the case in the grid. Solder a #12 to the case side and I'll have nose or base PC tray. I'll get some brass insert for 30 cal rifle and I'm good to go. Should do > 350/tray. Excess powder will go into the baggie to be recycled, the grid will allow the CB to be coated more completely than using a solid plate. Got a large sheet of the expanded steel for $10, another $11 for AC snips, 9mm cases are a plenty, so I can make several. Got a couple hundred cast to PC so I'll just do half the tray and see how well it works.
Interesting. What do you think about using some scrap 22lr shells for the stands and soldering those to the grid? The 22lr shell might be large enough to get the tip of a boolit into and help it stand up. I'm really liking the expanded metal option that you went with.
So looks like I ran into a roadblock that I have not read anyone else having. took some .356 Cast 9mm and PC'd them and of course, what is the first thing that I SHOULD have done but did not???? Check the size before putting them through the Lee Push through. You all see where this is going right? First two went through without much trouble but the third one is Stuck in there like it has been epoxied. I then took 3 samples and calipered them. .364 or .365 so looks like I have added 8-9 thousandths to the bullet and I am trying to size to .357. What on earth could I have done wrong and how do I fix it?? Harbor Freight gun and powder. This is obviously my first PC experience of any kind.
Has anyone tried this in a 460 S+W or 357 Sig? I think that I am going to try it on some 40'sand 45's first to get my feet wet. The Harbor Freight powder works well? Any other suggestions?
Can boolits be handled after being PC'ed, but before being baked? Also, can you shake boolits while PC is still in powder form without having the powder shake loose?
