Bullet bending and velocity

[Dresden]

This penetration issue is something I have interest in, not that I need it personally, I am mechanically inclined and this interests me.
Yesterday I was visiting a friend of mine that I worked with at Honeywell's Ordnance Division, he is a trained Gunsmith and Toolmaker, we both have 40 years in the trade under our belts.
I asked him about the velocity/penetration issue, as we both have heavy caliber rifles.
His take on the issue was at to high a velocity the bullet the bullet can bend when hitting bone, he also said hard cast wheel weight can shatter, he personally prefers the lower velocities, even if it limits range.
I found this web site yesterday and seeing their take on the issue is interesting.

I also read the Sledgehammer solids were such a problem that Federal stopped using them and now uses Woodleigh, Sledgehammer solids are no longer made.
There seems to be some people addressing the issue, finding them is more of a problem. I have noticed the following companies offering products.

This list is not an endorsement from me, I have bought bullets from the Montana Company.


I have loaded ammo with Sledgehammer solids, I am thinking of pulling a few and grinding a form tool to recut the nose profile.


I hope this is useful to some, but we all pay our money and make a choice.

I agree with the points you have made. With my 458, I find I have to be finicky with bullet selection above 2100 fps. Especially with longer bullets cut with canelures. The canelure tends to be a weak spot. Lowering velocity tends to reduce shock and hemmorage. When lowering velocity, I like to use gas-checked hard cast bullets with a meplat point and a caliber diameter cutting shoulder. (Ala Elmer Keith) with a 1700 fps load I can get 30" line of sight  penetration on American game. I get high shock and good hemmorage.

Thanks for replying, have a look at what this guy does for bullets he uses for hunting, it's  praiseworthy.
