Bullet Construction vs Lethality

Energy isn't so important with these. It's whether the petals break off or not. Velocity is the magic button with the design. Have you run any monos into game? I can't recall you posting personal terminal hunting results? Not a gotcha intent here, but trying to understand where you come from in your contributions.
The published min impact velocities has been set by Hammer. I've read some of their threads where they blamed tumbling on impact velocities or twist.
 
I wish you luck on getting an answer. I basically asked that same question WAY BACK on page 2!! I'd still like to know the OP answer and what testing was done to decide on a mushrooming bullet over one that sheds the nose petals.
There really is no conclusive test. Maybe you know of one, and if you do, do it and enlighten us all. All I know is while I was using Barnes bullets, they petal I assume you know, when they opened up they did very well. Their low BCs and inconsistent petaling motivated me to make a higher BC bullet that petaled more consistently and at a lower impact velocity. We aren't the only company that subscribes to the petaling behavior. Hornady and Nosler do as well. Petal shedding leads to less weight retention and requires a more brittle copper, and is largely confined to those that make lathe turned bullets. It seems that they are using free machining copper whose chips break off rather than forming ribbons. The petal shedding is probably a consequence of the more brittle alloy rather than any deliberate design feature. All I know is that my experience with our bullets and that of our customers is that even the light for caliber bullets cause the animals to either drop dead or not go more than 25-50 yds if they get hit in the mid chest broad side. All lead core bullets designed to expand, mushroom. All you have to do is try our bullets on game and you will see how quickly they fall dead. Look on the video I posted on FB showing a bull Elk hit at 400+ yds with a 7mm BD2 bullet. Look on the George Fournier page then tell us what you think. Also read the top post there. Guys at Jarret rifles did single shot kills on 2 Cape Buffs and a Hippo using our 300 gr .373 BD2. They also show a recovered bullet.
 
You're welcomed.
Your piece of paper vs mine is all that is, my corrected values (verified by shooting) are quite different than what StrelokPro came up with anyway, it seems when you get above 3800 fps the app doesn't align quite right, just my experience, is this gonna be the new argument, who's app is better?

So all you have to do is set up your range and shoot some of your loads out to distance. As you say those are corrected values right? So that means you have some groups out to that distance correct?
 
What kind of game are you wanting to play now?
Look you said you don't belong to a range and you could shoot out to a mile from your front porch. So it doesn't seem that difficult to verify your claims. You said that you have "my corrected values (verified by shooting) from shooting". So all of this is just to verify "facts" which is all part of this thread. If you don't want to then there is the end of the conversation.

I'm on the road and can't get to the dope book at the moment but here you go, the outlined box is my house,, the red ine is where one of the gongs is among many
