230 grain .45 vs 200 grain 10mm penetration and for bears/ hogs

Thanks for doing the research, 5pins. I am going to see how my Montana 20-grain WFNs perform over Blue Dot. If they disappoint, I may look into the CEB 190s for a hunting load. Still trying to figure out why you got early and significant pressure signs.  I wonder if CEB went to multiple narrow drive bands they would reduce pressure -- as Barnes learned with its TSX bullets.  Seems one way around the pressure issues often associated with monometal bullets.

I will second the looksie into Lehigh defense ammo. I load their 140 gr penetrator to 1450 fps (G20sf w/6" storm lake bbl).

That load will go through level IIIa body armor, 4" bulletproof glass, and about 30" of ballistic gel. So, it it's penetration you want,  there's your projectile.

See some of the you tube videos testing this bullet for reference.

Trust me on this one The Lehigh Defense ammo from Underwood is the "ultimate bad-boy" when it comes to accomplishing the task at hand. "Ruining someone's day" or harvesting game in the field, Underwood's Lehigh loads will "finish the task".

I picked up some of Underwood's 120 Grain Xtreme Defender 45 auto sometime ago, and might do ok, but yea, UW's 10mm 200, or 220gr hard cast is what want for big mean critters

New to forum. Old to this discussion. Best question to ask is what do you feel you are most capable with and what will be the duty of your firearm. I personally load the old ACP with a stiff load of 800x behind a 255gr Hunter Supply SWC. It rattled my metal targets just as hard as the 10mm with nuke loads of 180s. The numbers are just that, for comparing on paper. The animals don't know the difference between the two when the bullet smacks them in the boilermaker. That being said, know your purpose with the firearm and practice, practice, practice.

What kind of velocity you getting with that load?

Bears have been killed by arrows but I for one have no interest in trying to accomplish the feat. 

I've heard those 45acp failing to penetrate a dogs head urban legends as well.  Which by the way, I find complete rediculous even out of 3" barrel.

::::Terminal ballistics dont always follow the "rules" of logic and intuition.I knew of a gentleman who had some differences with his wife's social behavior and when informed of his displeasure she shot him in the head at a distance of inches of inches. Although it was a 25 auto it was still a potential lethal weapon. the little bullet didnt dig in well and skidded 6 or 7 inches around his skull under the skin. And as goes the urban legend it really pizzd him off.  In my next to last career I got to treat a number of animals that had been shot. One a Doberman was shot by an LEO who wa not a particularly good shot and was a bit "jumpy', perhaps with good reason. The 45ACP 185 hollow point + something hit the dog in the rt elbow, shattered the joint, disintegrated and failed to exit.  I was able to save the leg but not the joint.  The next case was a dispute between "neighbors" where the dog caught most of the animosity between the two. The big Rottweiler  was shot  in the head, left of center, destroying the eye and all the muscles of mastication, some of the ear structure and any other incidentals in the way. In the mess that resulted it became evident that the skull had taken a lot of the impact of the duck load but had not fractured(as far as could be determined) or penetrated.
  All three cases pretty much defy logic but such is nature of terminal ballistics. Repeating these results on demand might jst result in a lot of frustration. A bullet bouncing off a pit bulls head, quite possible, bouncing off a bears skull more likely still.
These cases are probably the rational of flat pointed bullets for dangerous game.
