Steve, are you sure about the 300 grain bullets? I think you must mean 200 grains, more or less. 200 is the normal bullet weight for the 44 Winchester.  
I may misunderstand you - are those cartridge weights?
  

Yes the entire cartrige all made up complete. Projectile , brass, primer, and powder. 
  

Here is the 44-40 Remington cartridge component time-line https://docs.google.com/spreadsheets/d/1pATGMkULsaPKtzmI7GYO_I0GOsoJELhyV-nl7Yl_fkc/edit?gid=1487708932#gid=1487708932

The head stamp on these say 44-40 WIN  R-P
They are in a styrofoam holder. No cardboard box left at all. Like I said I have had them forever. 
I could weigh the entire cartrige and see what someone here might have for comparison
  

Steve,  "When in doubt, do without" applies to more than questionable Winchesters.  I doubt the ammunition is high velocity stuff but Remington doesn't exist and you don't have the box with a description or a lot number.  
Weighing the powder charge and guessing what it might be is akin to slaughtering a goat and looking for answers in its entrails
My suggestion is to invest a small sum for a bullet puller for your press. RCBS makes one. Pull the bullets and set them aside. Dump the powder and put it on your lawn.. Load the primed cases with the powder of your choice in a safe, published quantity. Re-seat and crimp the bullets. You will have saved everything but the powder and can enjoy peace of mind. 
  

I am inclined to agree whole heartedly. I already have a puller. 

Yep it could be reloaded as well and who knows what kind of power could be in there. Might even be black powder. 

I did weigh up a half of dozen of them and the total weight varied several grains per bullet. Anywhere from 304.9 to 306.3 grains.

I confess that my first several reloading tools were Lee Loaders, which were only five 1966 Dollars and had everything you needed.  
My first and for many years only bench mounted press was an RCBS Rockchucker and I still.have it and use it.
  

I bought an RCBS Big Max press in the early 1980's.  Still have it.  Haven't used anything else since then.  It surely has been up to any job I've thrown at it.

Ok I have another question about the 44-40. Somewhere along my life I have had this box of 44-40 ammo. Seams like forever and I do not ever remember having anything to shoot it out of. I as m assuming it may be factory ammo but not sure. The bullet is flat nosed lead but  it is also a copper jacket. So my concern is did they make them in high velocity rounds for some other gun. Wish there was a way to tell?? Guess i could take one apart and weigh the bullet and the powder. Just trying to be careful. 
  

The 44 WHV cartridge is marked as such on the case head.

The predecessor to the No. 310 was the Ideal No. 3, No. 4, and No. 10.

I load 40-70 S.S. and 40-70 Ballard with an Ideal No. 3.
