      When leveling up your weapons it can take 7, 8, or 9 missions to fully level them up. The way you tell which is to take your brand new weapons on one single mission and check their progression in the progress bar. One solid square, no more no less, is considered a 9, as it will take you 9 missions to fully level it up. A weapon that is an 8 is slightly more than one square, and as before it will take you 8 missions to completely level it. Lastly but not least is the 7, which is one complete square, and almost half of another square but slightly less than 1 1/2. Again the 7 will take you exactly 7 mission completions to fully level the weapon. So from now on I'll be refering to these weapons as 7, 8, and 9's.

      Pick out whatever your weapon is and write down it's base stats  (base damage, range, reload speed, etc). The weapon must be new, as in no progress as indicated on the weapon's progress bar.  After purchasing the weapons, equip 4 at a time, as in 2 in the front, and 2 in your bays ( bay weapons level up as well). Go on one single mission, no more than 1 (it doesn't matter which mission you choose. It won't have any effect on how your weapons level up).

      Now you can do the formula: Take the new damage, range, and reload speed stats and subtract the base stats from them. Them you will multiply that number by how many times it takes completely level up the weapon (7, 8, or 9 times). After that add the base stat back to your total, and you can now accurately predict what your weapon will be upon completion.

      Note: These numbers aren't always whole numbers, so you might actually get slightly higher than you estimate (i.e. 100 might actually be 100.7 etc.).

The link to the original information about the "grinding weapons math" is.... i don't remember. It's been a long time and, if i had to guess,

Anyway, i didn't discover this myself. If you know the link, please put it here.
