Hi Ravenwolf,
Hmm, falling block pistol and rifle, almost sounds like a BF, and 97 D ??
Anyhow, I can't add much to what I posted below. Time ran short before hunting season. I plan on doing more load work as time and weather permits. I did find though the round, at least in my 15" Encore barrel, prefered the the slower H4350, over the Varget and RL15 that I had started with. Either Nosler 165 gr. BT's , or the Scirocco's 165's shot well.
It would be an excellent choice for your falling blocks, with more than enough power and range for the average needs.
I be posting more as I get the data
