A Question About a bullet's performance

3 Dmg, 2-4-6 pen

The figures I get from FFS are almost always Dam 4 Pen 2-3-Nil. About like a 7.62mm NATO. But with about 75% of the range.

I would just ignore their range value and keep damage/Pen the same.

If this helps at all here is how I am equating for my rules set:
20" Barrel length, Both FMJ:
.30-06 Dam: 6, Pen:x1, Range: (20x2.7)= 54 m (point blank range), Max Range: (54x20)= 1080 m
.270 Win Dam: 6, Pen:x1, Range: (20x3.1)= 62 m, Max Range: (62x20)= 1240 m

I determine range using a rng x multiplier = Vel (m/s) / 300. so a slow round will have a point blank range less than the barrel length etc.

As far as Penetration It has a lot to do with the bullet type. A FMJ will penetrate much better than an expanding hollow point. Which brings up a good point, just because it is a hollow point does not mean it is designed to expand on impact. Also a lot of armor piercing bullets will actually do less damage to a human target than many other types.
