This is a sized and De primed 45 colt brass. This particular brass has not been drilled but I am just using it to show as I do not have any blank brass that is not loaded.
Once the brass has been cleaned and deprimed it should be sized also but for blanks you can get away with not sizing the brass IF it will load into your gun with little problem.
Next it to prime the brass. Best and cheapest way is a lee eazy prime. They run about $25 and I use it to prime all my brass blanks and ammo loads. You will need large pistol primers.
Then put your brass in a loading block or if you do not wish to spend the money on one. I personally love them and would not load with out one. You can use a pie tin.
Then using a Lee dipper again you can pour your powder in but I find that way is messy and you loose a lot of powder and with the price I find a lee dipper much better and more consistent. A full set will run you about $10. Which one you will use will depend on the powder you use and the load you want.
Poor the powder into your brass.
Then take your paper wads.
Put then on top of your brass so they are flush with the top.
Then take a ram. This can be just about anything from a flat pencel or I like to use a 380 brass on the end of a pen cap. Use this to press the paper wad down into the brass. This part is very important. You MUST make sure that the paper wad is all the way down and pushed hard into the powder. You do not want any extra air in there. This will cause you problems.
This is what your finished blank should look like. How fare down the paper wad is will depend on how much of a load you want in your blank. 30 grains will take up most of the brass. This one in this picture has about 30 grains.
If you have any questions feel free to ask. Also you MUST drill your brass if you are using once fired 45 colt brass vs blank 45 colt brass. Regular brass the flash hole is not big enough and the primers back out and by your 3rd shot your gun will lock up. ONCE YOU DILL YOUR BRASS YOU CAN NOT LOAD IT AS AMMO. ONLY BLANKS.
You can drill it or you can buy blank brass from Midway USA on the net. About $25/100 plus shipping. Wich is a REALLY REALLY good price.
