DP,
Only point I was trying to make is that if you expect to bump into porky, you’d best be packing something better than birshot or Fosters – as a last resort, whatever you got is better than nothing. The advice I got many moons ago still holds true, “If you can’t outrun a deer, better to be able to climb like a monkey.”
There’s two different aspects of stopping something and they are 1- Making a kill shot and 2- Stopping ambulation. When it comes to speed of kill, the only two things that count are the size of the permanent wound channel and where it’s placed. It doesn’t matter if there’s pass-through or not except when the pass-through allows for faster bleed-out. It’s always amusing to poke fun at the loudenboomer megamagnums but truth be known, it doesn’t matter if you poke a 1” diameter hole through the boiler with a .338 Lapua or a .50 PRB, if the critter is intent on making a 100yds before it drops, what it was hit with matters not. When it comes to stopping ambulation, the only two concerns are 1- Does the projo have enough momentum to complete the task? and 2- Is the projo going to destroy all the meat or not in a hunting situation? There’s some scientific real world reliable data available on terminal ballistics, unfortunately the factual data gets overpowered by worthless sales hype and equally worthless gunshop myths. It’s like the example I used of the high velocity .22LR vs. the low velocity .22 CB Long, despite the vast velocity difference, the terminal effectiveness on small critters is vastly improved simply because the low velocity bullet design is such that is creates a far superior permanent wound channel – granted said wound channel is far shallower because the lighter & slower bullet has less momentum. I’ve never been one to be impressed by numbers on paper except for scores. Take the ft/lbs and MV tables, throw them in your hat and you’ve got a hat with wasted paper in it. The only thing one need be concerned with for hunting purposes are Shot Placement, Available Momentum & Permanent Wound Channel Diameter. Doesn’t matter how fast or slow the projo is going when it gets there, what matters is if it hits the right spot, that it has enough momentum to make a wound channel of sufficient diameter.
