Powder Coating

Lets discuss the important factor, how has everyones accuracy been? SO far the best ive managed was 13 inch at 100 yards with a 45 colt henry

Depends on a number of factors, i have tried 7mm rem mag powder coated that was minute of barn, and a friend has tried my powder coat 45-70 and achieved just over 1/2 inch at 50 yards.

weight,speed,bullet diameter, powders are all factors. You have to try many different combinations and it takes time like any other load testing.

I am happy with 9mm,40,45,300blk,44mag,45-70 using powder coat, i could not get 308,7mm rem mag to work no matter how much testing i did.

Be interesting on the 7mm and 308 to water drop the powder coated bullets right out of the oven, maybe a bit more heat and soak time.

the water-drop thing has been tried and no discernible benefit is achieved to boolit hardness. The cook temp for the powder just isn't hot enough to cause a change and if you do increase the heat enough with the powder on the bullet, they start to slump & deform under their own weight.

I personally have tried the extended time/more heat thing in the oven and have noticed no benefits. I have tried the same powders at 400 to 450 (just a dial setting on my stove, not a confirmed by thermometer reading) and noticed no ral change...if it cooks & sticks at 400 it will do the same at 450. I have read of some guys having better luck with a powder that is hard to get to stick with a longer cook time but no difference with temp change. Some attribute this to stoves that don't reach their advertised temp settings.
 
X 2 on the bullet casting then quenching process. I have personally found that this extra step offers no benefits for inducing hardness, only making bullets wet.

Powder coating my medium caliber bullets such as 38's & 9mm works very well, however when I switched to the bigger calibers, I used incrementally more powder and a bit more oven time to achieve satisfactory results....
 
Just checked the hardness of some that I cast 2 days ago. They are bare lead. I use a 3# pure lead and 1# ww mix. Air cooled is 9bnh, water dropped out of the mold is 12.5bnh. After coating the water dropped they are still 12.5bnh.

The non gas checked ones I have ran up to 1380-1400fps. Gas checks and coated I have only went to 1650 ish fps so far. According to many posts on cast boolits for hunting you would like to be around 11-15bnh to still get some deformation/expansion.

I used to shoot a 4:1 mix and they don't even register on the lee hardness chart. Had good results as well just not as good as 3:1
 
Accuracy. I've put 10 shots into under three inches at 100 yards and 2050 f/s with my Sharps .30/30 with iron sights.
Also, 10 shots into 2 & 7/8 at 200 yards with my tuned JRA Springfield 03A4.
 
Questions on powder coating. Is a powders coated more accurate than a naked lubed bullet? What is the powder for the coating made from? I assume you can get higher velocities wth powder coated bullet? Is it a time consuming messy job powder coating?.

1. Not sure about accuracy compared to lubed bullets as i haven't shot any normal lubed bullets for aboot 5 years.
2. The power is a polyester based product.
3. Some say you get higher velocities, i don't think its a big jump.
4. process is not messy unless you make it, it takes a total of 20 min to have a bullet powder coated and ready to load, 30 to 60 seconds to apply the pc, bake for 10 min and the rest of the time to let it cool.

Try youtube and search powder coat bullets
 
I put some powder coated bullets up against traditionally lubed bullets in my light .357 target loads. Same primer and powder for each. The PC bullets were about 12-14 fps faster. I got the same results with my 9mm loads.

Cast up about 300 bullets tonight using the new NOE 230 gr. 45 ACP mold my casting buddy picked up this week. The mold came with the HP pins installed but it also has cup point as well as FN pins which I plan to cast up some bullet with later. Took about ten pours to get the mold heated up but once I got things going I dropped bullets for a couple hours. Probably a few in the batch that I will cull out. I measured a couple set from each pot of lead cast and they all measured .453 on the money an weight 220 grs. These bullets will be getting PC'ed

Powder coated all the HP’s this morning did some in OD Green with a pinch of white and a few in Orange and changed out the HP pins to the cup point pins and did a few in two different colors of green.

Some in the coating tub before placing on the baking sheet.

Here is also a batch of my NOE clone of the Lyman 358156 HP mold I did in Signal Blue and Yellow/Green.

Damn fine job of casting and PCing. Where about are you in this country, if I don't have to pay the shipping all the ways across the country I would sure buy a handful of those .453 HP to try for gopher slugs for my 45-70.

Thanks, I appreciate the compliment,unfortunately I'm down in the lower 48 in North Carolina so shipping cost would be expensive. If you cast or know someone that does you could always get the same mold http://noebulletmolds.com/NV/index.php?cPath=41_427&osCsid=74vsckn10etteqb32gm31s5qe2

Which one of those do you have? I'm very much a beginner at casting so I'm not 100% sure of the differences apart from 2 cavity vs 4 cavity... These look like they should work great for Webley use as well as all my other .45 applications...

The rg 2 or 4 are hollow point moulds. There is also brass or aluminium. I have 2 noe aluminum moulds and they were about $150 in my hands. Well worth the price of admission
