Whilst i have previously discussed my preferences and caveats vis-a-vis Pyrodex and 777, I still will
use them when necessities arise -- ie "I can't get anything else".
Coffin -
i WENT TO THE WEBSITE, AND FOLLOWED THE 77 doco for cases explicitly:
Note that page 2 has catridge data for pistol and rifle...
https://www.nmlra.org/news/hodgdonsubstituteloadingdatayou know what, I am downloading this....
Since 777 is a sub, and is more difficult to ignite, I am not concerned about running it through a powder meter.
During the first great powder shortage, I found no smokeless available but plenty of 777.
I investigated, tested, and found that
- 777 meters nicely
- 777 works fine in straightwall cartridge cases when loaded as advised.
- it ismore energetis than BP as documented, but not significantly compared to smokeless, AND since it is based on black, the curve is "similar" to non-smokeless...
- In the event of nothing else I am willing to use 777 in any straightwall case, and clean very thouroughly
- I would rather use 777 than make my own BP (so far) ....
as always,
RTFM
