Read that WC872 works well in duplexing for main charge in 45/70. Yep, works great! Low SDs, good groups. Also read that it shines in 6.5-55 Swede pushing 140 gr jacketed bullets. My grandson has a 98 Mauser sporter that I built him, and last fall drew an Idaho moose tag.. I loaded him up some 140 gr Nosler Partitions over 55 gr WC872, and he smacked a nice trophy bull with one. Certifiable grave yard dead! I took a little 94 Swede out this evening, and used the same charge behind a Hornady 140 interlock on a butter-fat whitetail doe at 150 yds..same result. She will put in a cold hard winter in my freezer. Gotta love a cheap surplus powder getting all that done, for $7 per lb delivered!!
