Keep in mind that DMR's shooting hot will usually have longer MED's (Minimum Engagement Distance).
Also, FPS isn't everything. The extra 50 FPS might be nice to have but if you're inaccurate (stock which might have a high FPS variance, compared to someone shooting consistently +/- 2 FPS) it doesn't make a difference. Also I forget what the "magic number" is but I believe after around 430 FPS the BB behaves under different rules of physics and can be more inaccurate (due to turbulence or something? the BB is moving too fast and turbulence affects it more or something like that).
