Nitro: We live in the same city.
Have a friend use to hunt with (he's too old to hunt now, but not too old to shoot). He taught me to cast, and we both used cast bullets on deer.
Now this old guy believed (and still does) in using a 210gr. 30cal. cast bullet at 2300fps. It would usually shatter the front 1/2, sending framgnets into the body, and have the shank penetrate/tumble on through. Odd choice for an old guy, but that'show he used cast bullets for 50 years.
I used (and still do) a big heavy bullet (.379" , 460", or .515") at 1200-1600fps out of a softer alloy that MAY expand a bit without fragmenting, usually exits.
He killed deer,,,,I killed deer...but there as a differnce in effect. While I never lost a deer, mine did tend to run a bit after being hit huless big bones were broken (and with this load, I do aim to HIT / shatter the shoulder and prefer to hit the off side as well). He got more "fall down in a shower of sparks" kills where the deer basically fell into it's own shadow, but he also had to shoot more deer a second time.
That last isn't fair, as I was using a single shot, and there were times my deer would have gotten a second shot if I had one on immediate tap....but I still only got the drop-in-tracks effect when I shattered both shoulders or the spine...he got the effect from hitting just BEHIND the shoulders, missing the big bones.
