I just use the pistol data, 300mp meters very well in progressive press
Just got the new (2019) Alliant load data manual.
Seems they don't feel the demand for .44 magnum data needs to be listed for rifles; in this case the 1894.
Anyone have any data and/or done a work up on this powder? Specifically looking at the heavier bullets 270 gr. plus.
Respectfully, only first hand chrono data please and thanks.

SAAMI chamber pressure spec for .44 Magnum is the same for pistol and rifle. Any data you see published that is Laboratory tested will be safe for all .44 Magnum firearms made in the USA.
Go to the SAAMI website, all the info you need on pressure spec and chamber dimensions will be found there. They do not specify pistol or rifle, all data is the same.
20 inch barrel Marlins gain about 250-300 feet per second over published pistol velocities clocked from the 8.375 inch standard test barrel.

Thanks for the info. More specifically I was looking to match velocities to specific bullets, IE bonded, monolithic, heavier or more robust construction etc. Moose called in up-close (50-100 yds) in bush will be the quarry. Need all the OOMPH I can get from a 20 inch barrel and 300 grain bullets.

Not quite what your looking for but some reference for comparison once you get the data you want. 1894 Marlin 78 vintage. 25 300MP gave me an average of 1786 fps, 25.1 ES with a Hornady 240 HP. The Winchester white box 240 jsp gave 1839 fps ave, 10.5 ES
You need, "One book one caliber". I have these books for my .357 and 44 mag of which I have both rifle (Marlins) and pistols. They have pistol and rifle data in them.it's nice to see the rifle data. I usually cross reference them with Hodgdon and Alliant web site data.
I also have one for my 32 H&R. They list all the popular bullets and powders, great to have in your re-loading room.

Actually their data is for both rifle and revolver.

SAAMI 44 Remington Magnum for Centerfire Rifles - Page 21 and 33
It is up to the reader to decide what the differences are.

Longshotz,
I have not loaded this powder in the 44 mag. However, I have in other pistol cartridges in lever rifles. It performs well at pressures that burn the powder completely. In other words, not a reduced load powder. It likes higher pressure loads. The 44 mag should be a good choice.
A good firm crimp and mag primer with recommended loads for pistol will work in the lever gun. Expect move velocity than listed in the pistol data charts, quite a bit more.
Stay safe and use reliable load data. Here is a link to a post in the reloading section. You may find something in one of these references to provide more details/guidance. One is posted below.

Screenshot 2019-12-02 at 10.33.02 PM - Edited.png Screenshot 2019-12-02 at 10.37.01 PM - Edited.pngHere's the SAAMI cartridge/chamber drawings. The Maximum Average Pressure spec is the same 36,000 PSI for rifle and pistol. There are minor dimensional differences in chambers, due to the differences in revolver and rifle construction. Throat, bore, and groove diameter for rifle is bigger, the bullet is bigger. Notice that the rifle barrel is specified as 12 lands/grooves, with a 1 in 38" twist, meaning Marlin submitted the info to SAAMI for microgroove barrels. Pistol barrel is specified as 6 lands/grooves with a 1 in 20" twist.
Since the pressure specs are the same, pistol and rifle, reloading data is interchangeable, with normal cautions to start low and work up when testing new combinations or components.

With the Speer 300 gr bullet you can expect to get a little over 1500 fps from a rifle.
