Semisane,

I ran some numbers on that bullet and I'm not sure I would use it much beyond 150 yards even if launched at 2000 fps. At that speed it may not hold together on close shots and it drops below 800FP energy at around 155 yards (at my typical 6500 feet elevation). It slows even more at lower altitudes, at 500feet it drops below 800 FPE around 125 yards. Compare that to a 200SWwhich drops to 800 FPE around 280 yards at 500 feet elevation and 2000 fps launch speed.

My theory on light bullets is that there is a point of diminishing returns where the bullet becomes to light to be effective much beyond 125 yards. The trajectory of a 300 grainSW (1700fps)for instance is less than an inch different (at 200 yards) than a 250SW (1785)but has 25% more energy (both with 6"PBR sight ins). I don't think the deer is going to notice the impact point difference but the energy difference will be noticed. A lot of this is due to the BC of the bullet. Thats why a 200SW (2000fps) has similar energyto the 300SW (1700fps) out to around 200 yards. The trajectory of the 200 is much flater with half the drop of the 300 at 200 yards (6"PBR).
