In all seriousness the best few tips I have is to size to what your rifle likes, .311 for mine, then I gas check and QC. After that I rinse them in acetone and stand them up on non-stick foil, electrostatic coat, bake at 400F for 15 minutes (do not preheat), water quench, and PC again.

really made that too short of on started thread.

I have pced boolets, be doing pistol round for a while. have a hf gun and a craftsman. attempted a homemade gun, and fluidized, tumble. first time trying rifle boolits. set up ideas is what I was meaning. sorry for the confusion.

I don't have a pic of the 30's' but I pc the lee 230 grain 30 cal for 30-06, the biggest problem is not knocking them over. I shake and bake, but with the nu-wave (or much cheaper generic) you just place em on a non-stick surface that the hood will set on and bring the oven to the bullets. 161314
Those are for the wife's 38, but the same applies, and now I have a couple mdf disc so I can set one up while the other bakes.

Search for Beagle333 thread - he uses washers, NSAF - base down. Really keeps flash off the base. Cook on that tray or use hemostats to move to a NSAF coated tray in oven.

What about the mesh basket or tray approach? That may be more for the .224 sizes but I though folks have talked about doing it for 30's too. I have only done .312 x 160 grain which are a fat slightly short 7.62x39 and I was able to stand them up. Not sure the .314 x 200 grain for the Enfield will be as easy to keep from falling over. Heavy trays seem to be flatter trays, the thin one I had was sort of wavy. Made it so bullets had a little "lean" from the tray making it harder to get them in.

I tumble coat mine. 160gr Lee 2R TL.

One day I had nothing better to do so I used some furnace duct sheet metal to make a grid. Picture a up side down shallow cookie sheet with holes in it.

I simply take the boolits out of the shaker bowl and set them base down through the holes. It works good. Without it you basically have no choice but to bake them lying down. I'll try to get a photo up later. Here are some of the finished boolits.

I shoot .224 boolits in 22H, 22KH and 223. If I PC will I still need GCs or is the PC tough enough not to get blasted off in the throat. If the PC is tough enough, can I expect decent accuracy (1 1/2" at 100yds) around 2500fps. One mold is a snug fitting bore rider. How do I coat that without making the nose too big or how do I down size just the nose? How does one PC a nose rider .224 and get a good coverage on the base? Can they just be dumped on something and baked? Is anyone PCing .224s for a rifles higher velocity? Do you stand them on their base to cook them or does that prevent the base from covering well. I know that's a bunch of questions but I am interested in trying PC if it isn't too much hassel with these little pills. Paper patch works but it's more trouble than it's worth for the .224s.

.309 lee 200 gr boolits, PC'ed and all stacked on tray,......ready for the oven....nice and steady.....easy does it.....almost have tray in oven....just an inch more.....DOMINOE EFFECT!!!......:groner:

I then went and bought some washers.:bigsmyl2:

If you are doing .224" I think you can use the 1/4" square mesh to make a grid similar to the one I made from sheet metal. I've seen photos of them.

OK, that solves cooking them. Will the grid cause any coverage problems and will I still need GCs?

Motor
02-20-2016, 09:34 PM
I made mine so that any contact with the bullet is above the driving bands.

The need for gas checks depends on your load expectations and alloy.

To be perfectly honest the limits of non checked PCed boolits is still very much being learned.

If you've been following along it seems that a new term has come along. It's PJ or polymer jacket. :)

That was what I was referring to but when I posted but I couldn't remember the name. It's a strange name anyway for wire mesh. I wonder how it got such a name ?

I have a nu wave oven with an extra base, may I ask if you run it at the max of 350 degrees while PC'ing?

Yep, I just set.it to max for 20 min from cold. Temp should be too low, but I haven't had any problem with chipping or such. This 45 tc was pc'd(smokes gloss black), sized loaded and fired vertically into a 5 gal bucket of water. Had to dig it up about 16" into the clay under the bucket. Seems stuck.

I made a hardware cloth to do rifle bullet's yesterday. Didn't have any to PC so I filled it with already finished bullet's and walked around with it, worked great. Took a piece of 1/2" hardware cloth and cut a 1/2" opening in each corner. Folded all four side's 90* and done!

Onward with more questions. I have a bore rider .224 55gr boolit which fits the bore snug. Not wanting to increase the nose any, could I invert a cookie sheet, drill a bunch of .218 hole in it and put my boolits nose down in the holes and then spray coat the bottom half of the boolits then bake or would I have to move them to another pan to bake to keep the powder on the pan from gluing the boolits to the pan? Even if I moved them to a clean pan, would they still stick? Do I just need to forget the bore rider and coat a different boolit?

Motor
02-21-2016, 02:28 PM
That's a tough one to answer. Maybe if you broke them loose before they cooled it would work.

Or you could lay a sheet of NSAF over the pan and insert the bullet tips through the foil poking holes in it.

My question to you: Why do you think PCing the entire boolit would be undesirable? Don't you plan on sizing them after PC anyway?

I don't see the point in not PCing the front half or nose of the boolits.

He is referring to a "nose riding " bullet that the nose/ogive in front of the riding band is a perfect fit to the rifle land dia. (common practice in the BPCR game). PCing will bump the dia up to not be able to chamber the round. I would do the "hole in the sheet with bullets nose down" and then gun-coat them, leaving the nose bare.

I PC Lee 170,180, and 200 gr 308 bullets using the shake and bake method. I changed the rack out and used a 3/16 aluminum plate with a sheet of oven liner over it. I place the bullets standing up using a large curved Twizzlers and can reach about half way of tray. Very seldom will a bullet tip over since you are only closing the door and not moving the rack. Works well for me!

When you describe something, you have a picture in your mind of what it looks like...you can "see" it. The reader does not have your advantage of seeing what is described in his mind's eye. Pictures would help immensely.

We test fired a number of these gas checked Polymer Jacket 30 caliber 125 grain bullets. They were cast from range lead so they would be considered soft. The gas checks I made. The bullets were sprayed, partial cure and resprayed then checked and sized. At 3100 fps there was no sign of barrel leading or key-holing. Unfortunately at that velocity, there was little left of the bullets to examine after hitting the embankment.

As Motor so accurately stated we are just beginning to learn about this Polymer Jacket. About the only thing I can add to the discussion is, at the recommendation of a physicist and chemist both PhD's, the Polymer Jacket should be .002+" in thickness at the interface of the substrate. We do plan future testing using similar plain base bullets and accuracy tests. Good luck on your testing.

Here is an alternate solution to the problem of not being able to chamber one of the fully powder coated Lee bore rider type bullets. Bullets with gas checks already crimped can be heated in the oven or with a heat gun until the powder just sticks to the bullet ( trial and error starting at 150'F). A homemade fluid bed was used with just enough powder while in operation to cover the driving bands. The fluid bed reduces the mixture density to control the amount of powder applied and prevent clumping (same as making spinner baits). A quick dip was all that was required.

162675162676162677162678

This method allows the bullets to be seated to the normal length of an non coated bullet. First batch tested were more accurate than fully coated bullets which required deeper seating to chamber. No leading was noted in the first 50 rounds tested.

OK, details of the fluidizer please. I'd like something like that but use the HF gun static instead of heat. What membrane did you use?

Bama can you further explain "fluid bed"? Iwould like to try your method.

Bama
03-05-2016, 06:30 PM
The fluidized bed is made from the top segment of a PVC floor drain. The chromed grid was removed and it was screwed to a square of plastic. The bottom section was unscrewed and a 2" circle of brown paper bag was used as the membrane between the top and lower sections. A hole was drilled from the side of of the square plastic to the center and the a hole was drilled down to allow air to the inside of the floor drain. A needle valve was used to control air flow from a large fish tank air pump. There are a number plans on you tube to construct them. They are easy to build and when you finish --if you also fish, you can paint jigs an spinner baits. I have tried a number of membranes and am not satisfied with any I have tested to date. So far a thin paper bag seems to work best. Years ago (over 50) at a NASA demonstration, the presenter heated a penny and dipped it into a small fluidized bed. The coating was a almost a 100% coverage yet thin enough to clearly read "In God we trust". That is the level I am after. This will reduce the variability of the paint thickness as a result of bullet temperature.

The first is a top view of fluid bed. With the unit turned on the powder bubbles slightly and stirs and moves like water. It will almost double in powder height also so do not overfill. The second is a side view showing the air pump I am presently using. The picture on the right is why I made the one on the left--it was top heavy and was knocked over very easy hard to clean that much PC!! Anyone that is using this method please let me know if you find a better membrane or a slightly higher air pressure pump. I have tried up to 60# bond brown paper from 20# to 60#.

Thanks Bama. Look for the stuff used to vent air from hard drives or used as a flame-proof containers. Had a sample that was tested for an explosive preventer of an aircraft electronics box. If I can find the guy who did testing I'll post the product.
