Thread: 6mm Creedmoor vs 243

But I doubt that a big red hind hit in the hilar zone would notice the difference in the scenario above. She would be dead right there, either way

And when the range stretches out with the lower BC, speed shedding bullet, your chances of missing the hilar zone increase, especially in those pesky fickle gully winds blowing around the faces.

I’ve done heaps of drop tests at 200, 250, 300m with the .243 Win, to nail down my drops as well as I can. Various traditional hunting bullets, 85-100gr. Once I’ve got the ES down to acceptable levels and the drop from the point of aim is reasonably consistent, it’s the horizontal dispersion that raises big questions. Like… crikey… that was off to the left /right, enough to put the bullet slightly too far back on the deer, no problem. Picking those annoying downrange breezes you can’t really see is so hard, especially in our CNI winter conditions.

The >100gr 6mm bullets that have come along in the last few years shoot tighter at that range. They just handle the conditions that bit better, and for me have improved confidence no end at the ranges at which I wouldn’t take the shot with my .243… you’ve probably seen this before but seeing as how we’ve here… Gotta make some new vids.

Man that WHACK! is deafening on impact.
