It takes a 6.35 bullet.
The 3 most common RIFLE cartridges in use in WW I were probably the 30-06 (2800 fps), the 8mm Mauser (2700 fps), and the .303 Enfield (2500 fps).
No. Two entirely different cartridges.
Commonly called the 8mm Mauser, the bullet is actually 7.92mm, but that term is not in everyday use.
Let's use the correct term. The 7mm Mauser fires a 7x57 CARTRIDGE. The bullet is just the part that comes out of the barrel at high speed. The 7x57 name means that it fires a bullet that is 7mm in diameter from a cartridge case that is 57mm long.
If the bullet is not ball shaped, but conical (shaped like a missile or modern bullet), and it is pure lead (not copper jacketed) then it is most likely not prior to 1862; If it's jacketed probably not prior to 1871. Location of discovery will identify the bullet further (a battlefield or hunter's bullet). Cartridges Cartridges are marked on the bottom that can give a clue as to where it was produced. I once had some 8mm Mauser bullets in a box that I thought was German origin but they were actually Belgium. One clue was the color bands around the top that indicated armor-piercing. These color bands, if present, can also be helpful in identifying them.
There are several different models of Mauser rifle. Can you do anything to identify the model, arsenal it was manufactured at, and/or the nationality of the rifle? That it was made in 1946 does nothing to answer this question.
These are both designations for the 8mm Mauser cartridge. 8.2 x 57 was first used by Sako to distinguish between cartridges containing the larger .323" bullet from those with a .318" bullet. This had been the source of confusion for over a century. The designation is seen primarily in Scandanavian made rifles. The term 8mm Mauser is commonly used in the USA and elsewhere. I have also heard an unverified anecdote that the 8.2 designation was originally adopted by Sako because the Finnish game laws required a caliber larger than 8mm for moose. The .323 bullet of the 8mm Mauser cartridge is actually 8.2mm, so that's what Sako stamped on the barrels, making it legal for moose.
Do you mean 7.63mm Mauser, or perhaps 7.65mm parabellum? There is no 7.65mm Mauser, but the 7.63 was based on the 7.65mm Borchardt. Either way, it is a bottleneck cartridge, while .32 ACP, also know as 7.65mm Browning, is straight-walled. The two cartridges are in no way interchangeable.
The 30-06 shoots a bullet which is 7.62 mm in diameter, so the 30-06 is "bigger" in that sense. Several different weights of bullet are available in either caliber, so that's an undetermined variable. There are several different 7mm cartridges (7mm Mauser, 7mm Magnum, 7mm H&H, 7mm-08), so you have to be more specific when comparing ballistics.
Well if the spring is broken, take it to your local airsoft store and ask them to replace it for you. If you have experience with fixing airsoft guns you can just buy a compatible spring and install it you else, but it looks like you don't since your asking. If it is a cheaper airsoft gun unlike a 100 dollars or above weapon purchased form an airsoft retailer, dont bother fixing it. If its not do what I said above.
Which gun? A bullet fired from a rifle, such as the 1903 Springfield, K98 Mauser or SMLE can travel about 2600 to 2800 ft per second.
