Former Governor of Hawaiʻi George Ariyoshi passed away at the age of 100. Coincidentally, the largest political rally in Hawaiʻi was for Ariyoshi at the Aloha Stadium. They just started major demolition of the stadium a couple of days ago.
Dupont#5 part2-45 BALL ========= After ascertaining that the 80 year-old powder was still viable, I thought how cool it would be to try and recreate some military-style ball ammo with it since this powder was used to make WW2 era military ball ammo.
I had to obtain some projectiles first. I placed an order for some 230 gr FMJ from RMR Bullets. Just for fun, I also ordered some RMR "Idaho Silver" bullets to take care of those nasty werewolves.
For this part of the project, I decided to start really low and work up gradually. In part-1, I did make some 230 gr JHP loads with 4.7 grains and it was pretty slow. So I extrapolated that data and came up with 5.7 grains to make mil ball speed. The test gun was the Colt Gvt with 5.5" Bar-Sto bbl.
Test#1 used 5.2 gr. 230 gr. RMR FMJ LOA=1.260 Taper to 0.468-WW brass V=697 SD=24
Test#2 used 5.7 gr. V=802 SD=35
The target velocity was about 820 fps from that test gun, so it was close. FYI- 820 fps was the speed I got with real 70's era mil ball from that bbl. There were no signs of high pressure so I can bump up to 820 easily. The only worrisome thing I saw was the fairly high SD. I noticed this from the initial tests. I suppose that if I were 80 yrs old, I would be a little erratic too. LOL In the next part of this test, I'll bump up to 5.8 gr and shoot for accuracy impressions.
This is a test project to see how good or bad this can of 80 year old powder is. This was a new sealed can. The problem was that I could not find any load data. Apparently it was discontinued around 1945.
