This is where to ask questions and offer experiences about the art and science of ammunition building. Also observations about any acquired ammo.

Update:-
Having tried all possible ways I can think of to get the powder to stick to the bullets and being unsuccessful I obtained a Product Data Sheet from Harbor Freight and sent it, along with my observations on the problem, to the powder supplier in the UK.

I spoke to them yesterday on the phone and the only possible difference between their powder and Harbor Freights is that the HF powder contains a 'Nasty' which theirs doesn't ( EU Laws probably) . They confirmed that they sent various colours to some reloaders in Scandinavia who have not complained.

They have offered to do some trials for me so today I sent off a selection of cast bullets for them to test. Will wait and see what happens.

I spoke to ElectrostaticMAGIC on Friday to see if there had been any progress with the bullets I sent them last month.

They were very apologetic and said they had been very busy with a new product launch but they would put my problem at the top of their to do list.

Today I received an email with the results of their trial. They look very good. They are gun coated as opposed to electrostatic coated.

They are posting them back for me to assess.

Well the bullets arrived yesterday and the coating is fantastic.

I worked this idea out for spay coating. The bullet point does not engage the rifling but the base needs to be coated to protect is as gaschecks do. This set up should do it although I am still thinking about it.

I shall buy a a powder gun but because it will cost about £28 / $38 to ship it I will get our next guests in the gîte to bring it over for nothing! Unfortunately that will not be until July 8th but I can wait.

This morning I did a test on the materials that I hope to use for the powder coating system.

The plate was put into the electric oven at 200º C / 400º f and baked for 15 minutes.

TEST 1.jpg


As can be seen the bullets have all canted over a small amount.

Once the plate and bullets were cool I removed the bullets from the Blu Tack. As can be seen they came away cleanly and the Blu Tack was still malleable.

TEST 2.jpg


So, it looks like I may have developed a system, all be it not one for bulk production but enough for my use :)

OK, so here we go.
First make the support plates from 8 mm thick aluminium..

Drill 5 mm dia holes

PLATE IDEA 3.jpg


Use a 22 mm drill to clean the back of the holes.

PLATE IDEA 4.jpg


Counter sink the 5 mm holes on top using a 10 mm drill

PLATE IDEA 5.jpg


Holes for 100 bullets.

PLATE IDEA 6.jpg


To be continued :cool:

Next stage was to set up a plate to take some .303 British using small inserts of BluTack.
60 now ready to coat.
