Alliant 300-MP in K Hornet

[JeffinNZ]

Anyone shooting 300-MP in a K Hornet? Preliminary research suggests it is even better than Lil Gun.

If so, maybe it's good in 32-20 too. It really sounds possible. Should provide slower pressure rise while still good ignition characteristics. Good for cast accuracy too.

I have used it in my Ruger SBH Hunter in 41 mag and the Mosin Nagant rifle. Works great in these with excellent accuracy and the highest velocity in the 41 mag.
I do have a K hornet but haven't tried in this yet. I do need to do this.

It works good in reduced loads in the old shuetzen calibers when breach seating bullets, I'm experimenting with it in my 32/40 and 25/20 ss. In small rifle cals. when using higher pressure loads, it builds pressure quickly and I prefer AA1680 for such use. Both powders are hard to find these days.

The reason I ask is this is the standard Hornet data for 300-MP and a 40gr Ballistic Tip.

I've had success with it in my 300 bo ar15 with cast, and now I've loaded some for my 223bolt gun but haven't had a chance to shoot yet. It's very similar to h110 in appearance and in the burn chart. It's going to be interesting to know how it handles reduced capacity charges.
Leadmans statement about the mosin is also interesting, I for one would like to hear more about that 54r charge.
