Hopefully no one will get upset or have their feelings hurt about what I'm going to say, but hopefully we all realize that we are grown ups too....the truth is, and the truth will always be...Velocity is your friend....it helps your bullets performance on game...it aids in tissue destruction and impact/knockdown and trauma that is caused from your bullet......the Linebaugh Theory is a LIE....a 45 Colt will not out penetrate a 460 S&W if you use the same bullets and shoot them into the same media...it was and is absurd to even think that nonsense was factual (aka a 45 Colt with a cast bullet at 1200 fps out penetrates a 458 Win Mag with a African Grand Slam Solid at much higher velocities) people once though that velocity made bullets explode like fairy dust...hence why it was a popular belief that expanding bullets traveling faster than 1100 - 1200 fps could not reach and destroy the vitals of game animals the size of boar or larger....I've always said that such beliefs were nonsense and the people that perpetuated these untruths were lying...that hurts people's feelings, but it is and was and always will be the truth. Big, Heavy bullets that are properly constructed, moving fast, will out penetrate big, slow moving bullets. Sorry if that goes against what some may try to sell you (and No, this isn't an innuendo), it's just the FACTS.......
