Is a 40 round ball sufficient for deer hunting?

40 caliber has been legal to use here in Wyoming on all big game, since they started writing big game regulations...
Back in the day before man buns,well kept beards, plaid shirts and mom jeans, animals weren't made of kevlar, and no one ever saw a round ball bounce off of a flesh and blood critter. Place the ball where it needs to go and the work part of the hunt will begin.
 
Spence is spot on, I’ve killed many deer with my 40 caliber. I use a 395, .015 patch and 60 grains of powder. I’ve killed them out to 60 yards. The deers vitals are about the size of a paper plate, if you can consistently hit a paper plate at whatever yardage you practice at, then killing a deer at that yardage isn’t hard at all. My 395 ball has broken ribs, went through the shoulder and a few times got a complete pass through.
Just practice, practice practice...know your yardage, and know your animal.


This is good info. I’ve used a .40 for past 10 years, killed bucks n does n pigs with that same load...out to bout 100 yards and in.

I’ll add that a .40 punches a .40 hole and immediately starts expanding upon contact. Often you’ll find a flattened ball that expands almost twice the caliber.

Folks that really know and understand how a PRB works knows the PRB works exactly the same in every caliber.

The soft lead PRB is perhaps the deadliest of all projectiles, it hits, expands, typically dumps almost all of its usable energy before exiting or stopping just under the off side hide.

That bug eyed sow was killed at 35 yds, smacked dead center between eyes.

The big pig was about 40 yards broadside, never found the ball but that pig didn’t take a step.

Fellas a .40 is plenty for any deer, very accurate and very deadly as long as the shooter can put it in the vitals.
