1# that is not necessarily true you can have both just like any other load you have to develop it.
2# that usually happends when the jacket was on the verge of letting go from high RPM slower twist will solve that.
3# once again slower twist barrels will solve that, the right tool for the job, I have a 220 swift AI that has a 16 twist barrel
4# what do you think happens when a guy puts a supercharger on his mustang GT, yet that never stops them it can be fatal and it certainly shortens the equipments lifespan.

Dean, some day we should hook up and make the long trip to our Pa camp.
We can shoot out to 1400 from our yard when the leaves come down.
I have a friend nearby who owns about 2000 acres that had been a strip mine.
He has permanent steel targets out to 2000 yds he shoots at year round.
Bring any guns you own, but before you leave, you will find that you will have shot the 300 gr bullets that leave the muzzel at 3000 fps and preferably more than that much better than the others.
And if 5 other guys shoot, all 5 will have the same results.
The problem here is what each of us consider to be long range.
About any cartridge can be made to do pretty well out to even 1000 yds.
But for every 100 yds further, a few more of them will be out of it, regardless how fast they leave the muzzel.
Hunting guns are only good when you can hit things with them. And very few are good at doing that beyond 1000 yds.
