500 Jeffery vs 505 Gibbs
This is my plinking bullet for my 500 Jeffery. http://www.accuratemolds.com/b...bullet=51-700D-D.png

its a 700 grain gas check that I powder coat. I shoot it as low as 1700fps to my max at 2200fps. A real good Hog bullet.

Wow, how many hogs can you line up and shoot all the way through with that baby? Impressive.


Regards,

Chuck

Chuck that's a good question. I will let you know if I ever recover one. Those cast 700's surprised me at how much they can penetrate at modest velocities.

Its a real nice bullet if you cast your own. They aren't bad on the shoulder either.

Oh yeh? Wink
Here is a 777-grainer, sized to .511-caliber, gas-checked and lubed, total weight.

Starting load in 500 Mbogo is:

777-grain Cast Lyman No.2 (NEI mold #374, Hornady GC, LBT Blue Lube, sized to .511"): Hodgdon H-4831SC 100.0 grains >>>
1760 fps, 5346 fpe, from a 25" barrel of 1:10" twist, good load.

Picture of boolitt with cm rule:



Weight surprised the heck out of me, cast in Lyman No.2 alloy from this off-the-shelf mold from NEI Handtools.
I thought the "680" would refer to weight, they must have meant 780 in pure lead without the lube and gas check.
The as-cast boolitt in Lyman No.2 weighs about 760 grains and is .513" in diameter/caliber:



You can also start there and work up in the 500 Jeffery, if you must. Wink

Looks like plenty of firepower there Frank! What calibre is it?
