Those are the stats for the base 76mm gun.... The 90mm upgrade gun is 240 avg dmg, 173 avg pen and 7.27 rounds per minute. It has a 4 round magazine and takes approximately 25 seconds to reload that magazine. I'm at something like 24.7 seconds with BIA and fans. The top gun on the 50-100 has more like a 50 second magazine reload.
