Yes lets continue talking like we were there and knew the differences between both rifles past 300m.
?? One only has to examine examples of both rifles from the period to see & understand the difference, you need not have been in the thick of it during WW2 to notice the differences in quality and construction of a weapon.
For the game's purposes there should be no differences. Both rifles were often well made and did their jobs.
I disagree, this game is about realism, and as such the difference should be modelled.
I'm not sure where this myth comes from that the Mosin Nagant is such a poor quality weapon.
Have you ever actually held or seen one? The craftmanship of a wartime Mosin isn't exactly what some would describe as 'good'. The Mosin was crudely made, one needs only take a close look at how the various parts were milled to see that. Add to this the very crudely made ammunition available to the Mosin during the war, and you've got yourself a recipe for subpar accuracy.
The Karabiner 98K on the other hand was amongst the best crafted rifles of the war, alongside rifles such as the Swedish M96 (Also made in Germany) and the Swiss Karabiner 31. In addition to this the Mauser was fed ammunition made to very high quality standards.
It all makes a difference, one that should be felt ingame if it is to call itself realistic.
If you want a truly cruddy WW2 rifle, check out the Carcano carbines.
Now that IS a myth, having shot several of these rifles I can tell you that the Carcano is definitely not as crudely made as the Mosin. And the Carcano is also a very accurate rifle, heck Kennedy was in the head by one whilst on the move in a car.
