Heavy coating VS thin coating

[prs]

My last batches have been pretty heavily coated. When we first started this shaking in little plastic food tubs, the challenge was to get a decent coating. Now, I am using black airsoft beeds in a vibratory case cleaner and letting it run 10 minutes. Bake and size. The coating is much heavier than the "old days", heavy enough to fill the crimp groove too much! I think I will back off on my vibe times to maybe 3 minutes or whatever it takes to reveal a safe crimp groove for tube magazine rifles.

You do not want thick coatings. Uneven thick coats will change the dynamics of your rounds. And generally end up getting scraped off a bit while you are loading into the brass.

Cut back on your time. You should see only a 1 or 2 thou increase in size.

Once the PC is well coated, you can sift or grab with tweezers and tap off the excess coating.

Using a vibratory case cleaner there is really no need for BB's

some us plastic collanders drilled out so the BB's fall thorugh.

some use wire mesh baskets (pencil trays)
some punch holes in a paper bowl

I bought 2 bowls from dollar tree, marked, drilled and sanded the holes smooth


before top bowl


after in bottom bowl


I love this method, it easily contains all the PD and BB's

I shake for 10 to 15 seconds with BB,s and get a 1 to 2 thousandths coat with Smokes powder. I like the look of the bowl with the holes. It might speed up the process. I am fast with tweezers, I worked for 20 years as a grain inspector using tweezers to pick up and inspect kernels of grain.

Yes on what he said. Coated a couple hundred .30 cal. long-nosed bore riders this afternoon. Sized boolit nose(s) to .298 with my NOE set-up before PC; miked .300-.301 after coating with Smoke's Clear.

Thanks. Last 3 batches of about 12# each were done for 2 1/2 minutes and the boolit details were not obscured after baking. The 45 Colt 454-250-RF (PRS) boolits miked at .456" in 96-2.5-2.5 alloy (1/2 of Lyman #2) and easily sized to .454".

I shake & bake with ASBB. A light coating is all I want with a quality PC. I get zero leading & good accuracy.
