300 Grain 44 Mag Loads - Subsonic?

[Wiskey_33]

Got a pile of Hardcast 300 grain WFN 44 mag bullets (.430) that I’m wanting to load subsonic for my suppressed Henry X.

I’m usually shooting 240 grain so some help with the 300s staying subsonic would be appreciated.

WLP primers are a given.

What powders do you have?

I’ve used Unique for subsonic .44 Magnums with cast bullets in the 255grn range. I remember them being very accurate.

I’d have to dig around and see if I have the data. It was a load I worked up for a buddy, so I may not have retained it.

What powders do you have?

N320, Bullseye, Bluedot, 2400

Any of those would probably work. 2400 is a great powder and can be downloaded easily.
