I am currently in a friendly conversation in another forum with a member that claims his .44 mag Redhawk can get 900fpe at 150 yards.
I don't know any of the particulars, but this seems a stretch to me.
Am I all wet?

Can a math whiz do the "backward" calculation for foot pounds with a 240 gr bullet to find the velocity needed for 900 fpe? I've only had one cup of coffee this morning...
 
Not knowing the barrel length of the RedHawk being used, the 225 grain FTX factory loading could easily retain 1000 FPS at 150 yards with a 8" or longer barrele

The question was can a .44 magnum revolver achieve 900 foot pound ENERGY at 150 yards.
I just found that hard to believe.
Any contradictions are more than welcome.
 
Handloading manuals and a copy of Mannes' "Tables of Bullet Performance" (inexpensive) are indispensable for answering these questions quickly.
 
That bullet would still have to be going around 1300ish+FPS to obtain that energy at that distance if my rough math is correct and I believe that would be a stretch from a handgun for sure
 
Using JBM's ballistics calculator with the following data:

Bullet: 240gr Nosler JHP, G1=0.173
Powder: Lil'Gun, 24.5gr (Highest MV listed at Max Pwdr charge)
Barrel: 8.275"
MV: 1,582fps (Hodgdon's Reloading Data)

From JBM Ballistic Calculator:
Energy at Muzzle: 1582 ftlb
Energy at 150yd: 692 ftlb, Vel: 1,140 fps
Energy at 100yd: 848 ftlb, Vel: 1,262 fps

MV required for 900 ftlb @ 150yds: 1,833 fps

So maybe the other question...

Is the Redhawk capable of launching a .44 caliber bullet {225 grains or more} safely at 1800fps?
Is this a sane load?

Clarity

In 1973 Guns & Ammo on a magazine cover proclaimed that a Thompson Center Contender with a 10" barrel chambered in 30 Herrett had more energy at 100 yards than a 44 mag did at the muzzle.

That is one TOUGH Red Hawk, but I won't shoot those loads. I have three 30 Herrett barrels and owned a 7-1/2" Redhawk. At those energy levels, pain and suffering is beginning.
