wouldn’t send any 6mm bullets after deer at sub-2000fps.
No worse than archery hunting with bow and arrow? Learn tracking.
Absolute nonsense.
My son’s bow will penetrate through a deer with a ~200-220fps impact velocity with a ~350 grain arrow, it has an SD of over 0.8, pushing through a blade cutting over 1” diameter - CUTTING on contact instead of crushing tissue.
An 80grn 6mm bullet designed for 3400fps MV, but impacting at 1600fps is a drill bit.
Slow bullets which fail to expand aren’t arrows. “Tracking” a deer with a bullet diameter hole on one or both sides, and a tiny internal wound tract is not the same thing as tracking a deer with its heart and lung nearly cut in half by a broadhead, with an exit wound laid an inch open, and an exit an inch and a half.
Sierra #1530 would be my choice of bullet.
From Sierra’s webpage for the #1530 85 HPBT:
You’ll note, the “small cases” in pistol length barrels they’re mentioning here are still leaving the muzzle over 2500fps - a 6BR is sending it out over 2650, impacting over 2200fps for conventional hunting distances, and Sierra is still calling it a “hard bullet” for these velocities, suggesting it won’t open much at these speeds, and further, stating it’s really only viable for varmints at close distances… where it’s impact velocity is still 200-400fps HIGHER than being proposed here.
For perspective - Pushing this bullet at only 1800-2000 MV is equivalent to shooting over 450yrds on deer with this bullet from a 6BR handgun. Not exactly “the same thing as “close distance” on “varmints.”
I’d want far more confidence in expansion characteristics at 1500-1600fps impact velocity before I chased this particular rabbit. And again, if the kid is older than 5, we probably don’t need to chase the “reduced recoil 243win” rabbit any way.
