That's right. I don't have any 'real answer' so far, which is why I'm asking questions. Specifically the questions posed in the first post of this thread.
So... buckshot it is then? With it's inferior per-pellet energy delivery over shorter distances, its absolutely randomized patterning which changes with every shot, with fingers crossed that my one shot within 30 yards or less will hit one or two important organs?
Again, this is my question. Many, many hunters have hunted deer with buckshot, hence the name, buckshot. It's not rabbitshot nor crowshot, not pigeonshot nor snakeshot. It's buckshot, as in deer, the male kind specifically, probably because doeshot sounds too much like killing Bambi's mom and buckshot sounds more manly. Marketing type stuff.
With buckshot we have:
- outside practical range of maybe 30 yards, 50 yards if using a choke and knowing your shotgun very well, and basically counting on wounding or entirely missing the animal at any range significantly beyond this
- pattern entropy with a small number of projectiles striking the deer unpredictably within that pattern, sometimes killing the animal
- individual pellets delivering 160fpe or less every time, basically equivalent to CCI Stinger .22lr
Compare this to 9mm:
- practical range for delivering an accurate shot without significant bullet drop of about 70 yards
- pattern entropy equivalent, or group size, varying with the quality of the rifle and skill of the shooter, but generally within a 2" group over its effective range
- bullet delivering between 350fpe and 450fpe depending on distance within the effective range
I'm seeing a lot of what has happened pretty well every time someone is so audacious as to bring up this very subject. Somehow the conversations around 9mm and deer inspire a flood of irrelevant comments about more powerful cartridges. Which is not to say more powerful cartridges are not relevant in deer hunting, as obviously they are, but rather to point out that this is stepping outside the parameters of the discussion I've set up. Of course everyone is welcome to go on about their favourite deer cartridge... but there are loads and loads of other threads covering that, right? I raised this specific subject, asking about the use of what seems a randomly inaccurate, apparently grossly under-powered load, buckshot, and asked about opinions and experiences around why buckshot would be so widely used for deer hunting while 9mm seems so close to universally dismissed from the whole discussion.
My conclusion generally as I've seen this hashed over in a number of forums is that objections are primarily based on something like fudd logic. Hit the deer with the biggest stick possible and it's more likely to fall down dead, right? Hence the shotgun and buckshot load. A shotgun makes a loud boom, sends a cloud of death in the general direction of the target deer, and gives the shooter a big boost of confidence that all that power must be doing something right considering how loud and scary it was. Similar logic for a .30-06, though with some crossover, as that is an inherently accurate round, at least in a decent barrel. Ultimately, why not use a .50BMG for deer hunting? That way even if you graze the foreleg it'll drop dead, right? Why practice accurate shooting when you can vapourize the animal and be sure? Or heck, nuke it from orbit!
You get the idea, I hope? I'm asking about a somewhat subtle bit of basic math: which is superior, anything from 1 to maybe if you're lucky 5 small pellets hitting the deer in the right organs to kill it, or a single heavier projectile delivered with reasonable precision to a known-good location for accomplishing the desired result? If that question seems too difficult or if it triggers you, there are always hundreds of other discussions on CGN to take part in. Move along. It's not like any deer are in imminent danger of me rushing out and shooting at them with my PCC, as I made ABUNDANTLY CLEAR in the first post. I've not even challenged the CORE exam yet, though I read through all the study materials, twice, before taking my RPAL/PAL exams, just so as to be clear on relevant information. I found the migratory bird part especially enchanting. So complex! So many rules! Such subtle distinctions to observe when deciding what's fair game and what's illegal! So take a deep breath, relax, and decide whether you're interested in contributing to resolving my question. I'm perfectly happy to be ignored if there really isn't any knowledge out there to help resolve this. I'll be doing my own field testing at least a few times on practical simulated targets, as I also hinted at earlier.
