When I was in the USMC, just about every armory had a complement of Shotguns (Pump) along with the Rifles, Machine Guns, Etc... Those shotguns were NOT just for Guard duty. Hard to beat a shotgun...

I find it humorous that we see so many, so enthusiastic, so gushing over a new high velocity and odd caliber round. But then again; I guess it's been that way since the advent of smokeless powder....

Acquired mine in 1975 at the Marine PX in 29 Palms California. It has sized and reloaded literally numerous 100,000's of rounds of Rifle and Pistol. It has literally traveled "Around the World" 4...

Also - one might try "Powder Coating" which in my experience will get you an additional .001 to .002 diameter depending on powder coat and technique.

I loaded 5 rounds using 30 grains each of the No.7 Powder enhanced with the 2% Potassium Dichromate. Temps were about 70% with a humidity of 78% according to weather site. Velocities of the 5 round...

In post #120, Procter had postulated that addition of 1% to 5% of either ammonium dichromate or potassium dichromate (Accelerator's) might increase velocity (Mixture Burn Pressures). I ordered...

1. For many molds; they will cast .001 to .003 over size.

2. The alloy used will result in different sizes of boolits cast from a specific mold.

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.

Velocities:...

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...

Ammonium Nitrate is available at many of the "Sporting Goods Stores", it sells as the product - Tannerite. The pills of white Ammonium Nitrate have to be ground to a fine powder. They come in 1/2...

Common in Korea (North and South), as well as portions of China to the North of Korean Peninsula. Called Ondol Heating. Great feeling in the dead of winter with the toes nice and toasty. ...

Ten test rounds were loaded with the No.7 Powder that remained from the test described in post #103 above. Powder was dried in a dehydrator (not cooked) as previously discussed, screened to fall...
