One of the most asked questions about coated boolits is how accurate are they. A good point as it is some work to do and we all ask at one time or another 'is it worth it'. I would say 80% or more of the coated boolits are handgun boolits. Hence I made this up using 9mm Luger on top of promo powder. All boolits have the same charge. Top left of each target is jacketed handloads to give comparison. Only minor changes to the load were done to make the jacketed a similar velocity (per the load book, not a chrony)
So lets see how they did:
Ignore the right side if this target, it clipped on my scanner. The image below shows that side.
A descent group with jacketed (Top left). An incredible group with the powder coated (bottom left). Doubt I'll get 5 in that small a ring again.
Now to the right side. Top right is Hi-Tek. Looks like a good group that was marred with a flyer. I think the flyer was the shooter not the coating.(top right)
Bottom right labled Hybrid. This was an experiment. I took some of my first powder coated boolits that did not get a good coating at all from my reject bin. They had an incredibly thin coating and lots of lead visible. I then gave a single hi-tek coating. Although thoroughly coated it did not work out, as the group shows. Hey this is all about experimenting right
Now for a second run. Top left is jacketed. Top right is Hi-Tek. Both on the bottom are powder coated. 2 different batches, but same method.
So a few final thoughts.
First I hope this helps some people out. I tried my best to make this as non biased as possible. The powder coated boolits were coated base down with an electrostatic spray gun. The base was not coated. For the hi-tek, I used the instructions and also advice on this forum. This was only my third batch of them, However I do believe it was a proper and successful coating.
All batches used (powdercoat and hi-tek)passed the acetone and smash tests.
The gun used is clone of an mp5, SBR. I chose a carbine as I could use a rest at the front and get the best accuracy while eliminating as much as possible effect from the gun itself. Distance was approximately 15 yards. Unfortunately with all the coating I have been doing, I did not have any normal lubed lead boolits to bring. Maybe in the future if anyone wants I'll do another set with them included.
I did not use any piglet method of coated boolits as I do not feel I have the process down well enough to make a fair representation of that process.
