A while back I bought a bunch of surplus WC820 powder (the original application was for the .30 Carbine). This stuff is supposed to load somewhere between AA9 and H110. I decided to do some experimenting to find a .44 Mag load for my 8" Colt Anaconda. Here are the results.
I used 240gr Hornady JHP bullets, CCI large pistol magnum primers, and new Starline brass. As a benchmark, I compared it to some Magtech factory ammo with 240gr JSP bullets. I fired 20 shots of each load over my chrono from a rest.
Magtech ammo:
Avg velocity = 1251 fps - Velocity spread = 95 fps - Standard Deviation = 29
WC820 Loads:
19.0grs: Avg = 1297 - Spread = 67 - SD = 18
19.5grs: Avg = 1320 - Spread =110 - SD = 31
20.0grs: Avg = 1340 - Spread = 64 - SD = 30
20.5grs: Avg = 1374 - Spread = 55 - SD = 17
21.0grs: Avg = 1410 - Spread =107 - SD = 30
The best accuracy was obtained with the 20.5 grain load. I shot a 4" group at 50 yards while I was tired; these will probably shoot better than that.
I love Unique. Sure, it's dirty but it's cheap and I can do light plinking loads and heavy hunting loads as well. I use the stuff in every caliber I own.
296 or H110 are one and the same.Unique for light loads, 296 for heavy.
296 or H110 are one and the same.
BG,
Why do you state that Winchester 296 and Hodgdon (sp) H110 are the same?
I would not think that one or the other is repackaging the others product and relabeling. I've burnt up quite a bit of 296 and some H110 as well. The 296 has a very distinct odor when lit. Definately smells different than the H110. I personally have not had them side by side under a microscope to compare.
