I've been waiting for a day like today to get some chronograph/accuracy data from my American Classic II, .45 ACP... a bright cloudy day with no wind. Today was also the first time I've fired boolits from my new Arsenal Mold. I wanted to compare it with the Lee 200-grain SWC, but, even though I was positive I had 50 rounds loaded I couldn't find them.

The boolit drops 227 grains from my 50/50 COWW/SOWW alloy, and the mold was an absolute joy to use.
So here's the load data...
Cases - IMI Match and PMC
Primer - Federal 150
Propellant - 5.0 grains Bullseye
Lube - My homemade stuff, I couldn't duplicate it if I wanted to.
The chronograph data was impressive as far as ballistic uniformity. I ran 100 rounds over the sky screens located 7 feet down range from the muzzle. Five 20 round strings... slow fire and rapid fire with each head stamp, and then a 20 round string of mixed head stamps.
String #1 - 842 FPS average, 29 FPS extreme spread.
String #2 - 841 FPS average, 7 FPS extreme spread (that ain't a typo... 7 FPS for 20 rounds).
String #3 - 842 FPS average, 26 FPS extreme spread.
String #4 - 842 FPS average, 34 FPS extreme spread.
String #5 - 840 FPS average, 27 FPS extreme spread.
I wish I could report tiny groups, but the guy pressing the trigger wasn't holding up his end from the get-go. It's been some time since I've shot a handgun from sand bags, and I'm pretty rusty... and no doubt the muggy conditions and last night's whiskey amplified that. I didn't even bother to change the target... I wasn't in the game. Still, all 100 rounds would have clanked a 6-inch steel pate with a bit of room to spare (25 yards).
Anyway, I've got a few hundred of the Lee 200 grain SWCs cast, sized, and lubed... and since then I've removed the bevel-base from the mold. My plan is to test the difference between the bevel-base and the flat base... report pending.
