From my experience and reading what Model70guy reports, I don't know if monos, "faster the better" , is an open ended principle.

Intuitively, maybe. But where the rubber meets the road, maybe not.

One poster mentioned needing an S.D. above .20, whereas some of the lighter Barnes mentioned, S.D.s fall below that value.

So, seems to me, too small a mono, driven too fast can have less effective terminal ballistics than one would think.

I doubt Model70guy uses that combo again.

Hypervelocity, low S.D. monos are no longer on my radar.

DF, there are exceptions to every rule. Ive been using a 95 grain TTSX in 6.8spc screaming along at a leisurely 2900 fps....but that particular bullet is designed to open well at 6.8 velocities....and it does grin


Ive got pics if you need them..... wink

I believe you, have also seen TTSX's open and perform well.

I think we're seeing light weight, low S.D. monos driven at warp speed not delivering effective/efficient terminal performance, may have reached their point of diminishing returns.

3,900 fps is way different than 2,900 fps, opens a whole new can of worms....
