I thought about taking the accubrake or sending it to a machine shop i know who make chokes etc and have them making a longer version with more gas ports?.
Longer shot i know of with a .458 bullet is 1750 yards . 45/70 350 grain 2100 fps solid out of a sharps replica .I know if a 45/70 can do it a 460 can do it faster therefore more accurate. How about this @ 3200 fps ?

I have also machined some of the 500gr banded solids and the triple shock Barnes a
after placeing a secant ojive and a boat tail on the solids they weighed 425 grains, The
Barnes triple shocks ended up at 450grs. I was experimenting with a 45/120 sharps
for long range and they out shot all other available bullets.
Also I did the same thing to some 400 grain 416 bullets and they were phenomenal
and shot the best group in my life (.034 center to center @ 100 yards).
So if you know anyone that is a good machinist you could make some bullets that had
some good BCs. (The 500 triple shock has a BC of .526) and if you boat tailed them it
should get a little better.)
Most people find it hard to even get a 1000 yard shot on Elk so being practical I would
think it would work very well on Elk and as for the tissue damage there is normally
much less with big bullets .
And by the way the Hornady leverevolution bullets don't hold up at such high velocities
because the are designed for 2500ft/sec and down (Impact velocities are normally below
2000 ft/sec)
PS: the accubrake is a baffled/chambered type brake and is reported to reduce recoil
by 54%. I don't know how accurate those % are but I do know they really work because
I removed one from an accumark in 30/378 and fired it and there was a tremendous
difference in recoil.
If you want one buy one.
Just my 2 cents
