Nosler 300grn and H110 44mag question

[fridge450]

Hello everyone just wondering if any of you have used this combination from the nosler website the listed velocities and powder charges seem a little high compared to other loading manuals with 300 grn projectiles. I will be using these in a 7.5 inch super Blackhawk and most likely using new hornady brass thanks for any imput.

There's 300 grain H110 data on Hodgdon's site. Velocities are out of a slightly longer barrel( a whole .75").
Isn't unusual that Nosler's data is different. 1.5 grains isn't going to do anything to your Ruger and Nosler used an 8.25" barrel with a different twist.
