It's all about placing your shot right.
Actually that's a very wide open statement, and it applies to every caliber and powder charge PRB combo that is used for game.
And you made no qualifying comments about using your .40cal...so on its face, your post implies that your new .40cal will be equivalent to a .58cal for example...and I'm sure you couldn't have possibly meant that.
Of course perfect shot placement is the goal...everybody knows that...and its the goal of every caliber/gauge projectile used.
The problem is actually "delivering" that perfect shot placement under hunting conditions of low light, shadows, slightly unseen angles, a deer starts to turn just as the sear breaks and gets a shoulder in the way and the list goes on and on.
So assuming you didn't mean to imply that the tiny 92grn .40cal ball is equal to all larger calibers/gauges...distance limitation is the only variable that can come close to leveling the playing field of comparing a tiny caliber 92grn ball to the larger caliber PRBs, with their greater frontal area, greater weight, normally greater velocity at distance than smaller balls, and of course greater penetration in spite of heavy bone unexpectedly getting in the way, etc.
Since I have a new .40cal myself that I haven't fired yet, curious what your qualifier will be to make your .40cal perform like a larger caliber deer rifle...for example, a 25yd limit with standing broadside heart shots only?
