Once again; not being a chemist - Thought it might be beneficial to "Look Up" the difference between Methanol and Isopropyl alcohol.



Methanol consists of a methyl group (a carbon with three...

Mixture already has KN03, so perhaps adjustments may have impact.

I have had a parallel thought for a couple of months that down stream I would attempt to make some "Gun Cotton", and use it as an...

This is interesting. I have been considering exactly this as an experiment for making No.7 powder over the last couple of months. I keep a dozen or so bottles of 70% Denatured alcohol (sourced at...

So the Puck of No.7 Powder made while attempting to make "Stick Powder" described above completed a 24 hour drying cycle in the electric Dehydrator at 130 degrees. I crushed the puck and...

My thoughts are that during the production of Nitro Cellulose (used to make Commercial Smokeless Powders since the late 1800’s – NOT USED IN PRODUCING No.7 POWDER); the cotton or wooden fibers used...

As I continued to turn the compression crank, resistance dramatically increased. It became apparent that I was about to experience a repeat of my first attempt weeks ago where the Extrusion Cap...

I placed the mixture into the Spaghetti Press; and twisted the compression crank slowly. Under compression; excess black water began to come through the extrusion holes:

My thoughts on attempting to improve the granule structure beyond screening resulted in me once again attempting to use a Spaghetti Press to make a for of extruded sticks (similar to IMR powders from...

Shot the 5 Test rounds this afternoon. Temperature was about 57 degrees, with a light drizzle. Target was a 7/8 inch spotter on standard 8 ½ x 11 inch letter paper; at 100 Yards.

The No.7 Powder in this test was screened with 2/3 of the Granules falling through 10 Mesh screen and being trapped on a 20 Mesh screen; 1/3 of the Granules screened to fall through a 20 mesh screen...

I loaded 5 rounds of .308 Winchester using 32 grains of the IGP )Plus Iron Oxide and Charcoal). The bullet used was an RCBS 200 Sil, powder coated, and an aluminum gas check. I used CCI #200 Large...

Given the poor performance of my previous IGP (Improved Golden Powder) experiment in the Remington 700 Chambered for .308 Winchester; I thought I needed some form of change to seek dramatic...

Unknown. Only way to know is to give it a try. Cost is not to dramatic for experimentation with a 1/2 pound to a pound of it and the other chemicals.


My current question/dilemma is: can...

Making a reliable assessment of the two powders based on 5 rounds each could be problematic; but I believe we are getting some indicators. It appears that Charcoal (A4-Rev1) as a replacement for...

I tested the 5 rounds loaded with A4 Rev-1 Powder (Contains Charcoal instead of Hydrocellulose). The rounds were fired in a Remington 700 in .308 Winchester with a 26 inch barrel at a range of 100...

I was able to get to free a couple of hours this afternoon to spend at the Range. Tested the 5 rounds loaded with A4 Rev-0 Powder (Contains Hydrocellulose). The rounds were fired in a Remington 700...

Finished producing the A4 (Rev-1) Powder. Replacing the Hydrocellulose with Charcoal was listed as an option for the A4 powder in the 1944 Paper entitled - Primers for Small Arms Cartridges by...

All my charcoal is home made. I burn pine and Larch (Seasoned 18 to 48 months) as primary heat for the Montana House in the Winter. Each morning I pick out the best looking "Charcoal" pieces when...
