"OK, OK, I'm going as fast as I don't want to go!"
Ok so when I went out for my "Christmas Eve Family Shoot", I also took the '03 Springfield to try out some cast bullets plus run some of that Swedish powder from those red wood blanks side by side with Unique.
This powder is known as Gevärsexerciskrut 1 or Rifle Practice Powder #1. Now, the reason I did this was because i have pulled down 10,000 of these rounds. Primarily because they were dirt cheap from J&G sales in Prescott AZ and because they were arsenal reloaded from range brass with non-corrosive Berdan primers. This left me with a lifetime supply of primed brass for my Swedish Mauser.
Now, what to do with something in the area of 30-40 pounds of powder.
I did a bunch of research around the net and gathered lots of data from the likes of Doc AV and others.
Some guys had ran up their load data and said that with cast bullets in Rifle data ONLY, they had found the numbers to be close to Unique. Others claimed it was a fast pistol powder but I personally did not have good luck in that area of testing. I ended up with unburnt powder and the velocity dropped when i was almost to the target base load.
So, going into the rifle tests, i had much better luck. In my side by side testing with Unique, i found the Swedish powder to be just a little faster but good enough results to use! This is great news considering the cost of powder and how much of this stuff i have stock piled up.
12 gr of Unique gave me a velocity of 966 fps.
12 gr of the Swede powder gave me 1200 fps.
The next step to solidify my results will be to run about 20 rounds at 13 grains and monitor the consistency spread.
I would have performed that yesterday but wanted to spend time on the family fun shoot.
So far so good though.
The target below is a combination of some FMJ for warming up the rifle, Unique and the Swede powder from the blanks at 50 yards.
One last note; many out there will claim that blanks have a flash powder in them. While this appears true as I have pulled down tons of Military ammo, this is NOT the case with these Swedish blanks. This statement comes from several gents who were in the Swedish Military and had access to this data.
