As the title says...

I can't seem to find any data concerning a setup like this. I realize this is a uncommon setup, but I am wits end looking online for info.
So I thought I'd ask the collective minds here.

I have a friend that has spare time on his hands, and has caught the ELR bug.
Currently he is pursuing Barnes projectiles... however I mentioned there are considerably sleeker .416 bullets available.

Any help is greatly appreciated.

Your issue is going to be twist in that rifle. All the 416 cal ELR bullets are going to need a twist faster than what the standard was on those guns.
