Not sure if this thread is too old to be read...
I'm really happy to hear so many like the .444! I've bought one for my wife as a saddle gun.. Have been looking for some tried loads for the 180xtp's (I have a pile of them), before I started experimenting on my own.. I'd like her to get used to the open sights and the lever action before hunting season next fall.
I LOVE my 45/70 GBL!! My practice rounds have been with the Hornady 300HP's. I didn't have any milk jugs to fill with water the day I got this beast, found a metal coffee can, filled it with water, put on the plastic lid and set it upside down at 50yds,, I won't do that again,, spent 25 minutes picking up all the shards of metal from the can.. the largest being about the size of a piece of banana peel...
Looked like a bomb went off in the pasture! Pretty cool!
Anxious to get the .444 going!
