Home Forums Reloading Big Game Rifles Maybe we obsess too much

At the end of the day I like to decide what matters for me based on my own results.

1000 yards prone/sling/irons groups

.284 Win, 184 Bergers SD 5.4 FPS Vertical 6.56"



.308 Win 155 Bergers SD 13.1FPS Vertical 16.37"



This group has double the shots of the first, but you can clearly see the elevation differences corresponding different velocities shown on the right.

The "positive compensation" effect mentioned in other posts above is not to be discounted, but I'm not certain it can be relied upon over different conditions.

Postscript: For those not familiar with acoustical targets (Etargets) the velocities shown are read at the target face. I find they tend to have a greater spread than at the muzzle due to varying individual bullet BCs, winds during their 1000 yard trip etc. , but I digress... or is that obsess??
