 Just bought some VV N133, "IF" anyone has tried it in our 76s', please, (40-60's & 45-60's) let me know how it worked for you.
  Will be chrono-ing some loads today.

    Took my "Range Box", for loading in the field and worked up 6 different loads using LEE dippers & a digital scale to verify my loads.
  Took a friend (fellow shooter) to do the shooting, i did the loading.

  40-60 chaparral w/ 26"- barrel, w/ vernier back sight, green dot front sight.
   Starline Brass 45-70 sized to 40-60 WCF.
   Brass OAL 1.885, w/ 403168 (Lyman) @ .214-.215gn. PC'd. OAL 2.260.
   Using Vihita Vuori N133.
   1st load 22.5gns= 1011 fps. ended up at 28.0gns for a 2 shot average of 1361 fps. "BUT" the thing that surprised both myself & my friend was they all shot to the same hole. We only shot 25yds to chro our loads. (3/4" c/c).

   My shooter shot his 45-70 RRB (one i had rebuilt) w/ N133 , and got the same results, 3 in one hole 2 on the edge of the 3 holes.
   To say we were impressed w/ our results would be a understatement, we both think we have found the powder for " our" rifles.
   YOUR millage may very, start low work up be safe.
