Mauser too accurate? My ass! Of course it's accurate, it's a freaking bolt-action rifle!!!!!!!

Have you ever tried to use that weapon? You wouldn't be saying it is "too powerful" if you had.
I agree with most of what you say, madrebel, but there are a couple things I must mention:
1. Why reduce the damage on the M1? Rifles require the most skill in my opinion, and are way too weak in the regular version.
2. It would seem more "realistic" to me to simply reduce the accuracy on the st-44, and leave the damage the same...
