Trajectory charts and calculations are useless. The only sure way to know what your gun will do is to go do it.
What would the trajectory be at around 100 yards?
Point Blank ballistics calculator:

Most reloading manuals will have a section that you can calculate bullet drop over range but you need to know several things.
Bullet coefficient.
Muzzle velocity.
This will get you in the ball park but,,, the others have the best idea. Shoot at the top of a target from a bench hold at 50 yards and get a decent pattern then move the target to 100 and use the same place on the target.
One thing, you must have the height of the gun above ground the same (close as possible) to the height of the aim point of the target. At 0 yards, 50 and 100 yards. Otherwise your adding or subtracting height to the bullets trajectory as it goes down range and making this kind of test useless.

After years of owning shooting and reloading for various 44mags I agree with 1-DAB
Charts and graphs get you in the ball park but the only true way to know is go shoot it.
300 gr LRN at 850 FPS should fall aprox 5 - 6 inched below point of aim based on the limited info you gave.

My son bought a Ruger 77/44 as a deer hunting walking gun . The little rifle is a keeper . I mounted a scope and sighted it in at 50 years with XTP 240 gr. at around 1450 fps . A five shot group was a good 3/4 inch . Next I tried the 300gr XTP at 1300 fps it shot 5 inches low at 50 YD but 9 inches low at 100 YD. The 240 XTP did 2 inches low at 100YD .

You're had a taste of the sweet nature of pushing hot 44's down a rifle barrel : ) You should be able to get MOA at 100 as well with a good load.My son bought a Ruger 77/44 as a deer hunting walking gun .

Getting MOA at a 100 yards is not a real problem . But using it in the field can be a big problem . The 240gr. XTP shoots a lot flatter and on a deer size target would make very little difference if it was 50 yards or 100 .
The 300 gr. XTP is a great if every deer you would like to shoot is 100 yards ?
When the 240Gr. XTP will shoot within 2 inches from 50 to 100 yards .

I do load the 240 xtps and like them alot. I'm trying some 260'ish FN lead bullets and that's a bit more work finding the right load--but when I do I'm sure it will be an atomic bomb for deer when pushed fast. My little rossi carbine prefers hot loads over more moderate ones. Anyway--apologies to OP and not meaning to drift off-topic.
