No need to get your panties in a wad Hand.
Too each his own.
It only makes sense to me , as you said “one well placed hole will drop it in its tracks”.
Then two well placed balls would be twice as good,
No one was talking about shoot two balls in “hope” of hitting the intended target. We were speaking of tested loads!
I don’t know how many deer you’ve killed , but I’ve taken several.
Some dropped DRT, others I’ve never recovered, even with a well place shot.
A lot depends on the terrain , our hunting in the South East contains heavy thickets that Whitetails love.
When they all all worked up chasing Does , adrenaline flowing they don’t usually just fall over. Even with a well placed shot.
At least not from what I’ve witnessed over the last 40+ years of hunting them.
Again In “My” way of thinking, two holes ,two drops of blood, one hole ,one drop, at night on your hands and knees it does make a BIG difference.
Not all of our hunting seasons fall in the cooler months.
I love shooting Roundballs , but in reality they are propbaly not the best choice for hunting projectiles.
They will kill, but your accuracy is limited.
Each persons is different.
As too the lazy part, lol
I bet as hard as I try I can’t load two faster than you can one.....
If I hunted in the Western States, I would probably never shoot two balls for deer, I would be pushing the limits on powder charge trying too string out a few extra yards.... like many do.
DRT at 300 yards with a muzzleloader !
It can be done.... but not by many.
Too me shooting two balls up close , accurately at a deer,
Again would be better than hoping you get lucky on one at 300.
Too each his own...
