conicals for .58 Hawken

[rushlake1]

This is the .58 maxi I lathe bored from a used mold in the cupboard.
It weighs 640 grains and is very accurate to the 100 yards tested.
The accuracy load is 150 grains of 2F Goex but one needs a very thick PAST shoulder pad to tame it down.
The recoil is BRISK and the Chronograph read 1400 FPS.
I was getting and honest four inch group at 100 yards until I quit, I couldn't stand to shoot it any more.

-------------------------------------------------
MD..Just Wow!..Bet that thing created a vacuum wave...
1 Month ago I was working up hunting loads for a 42" 1-66 Rice flint 58 cal.barrel

15 ft from the muzzle I was getting 1600fps....
at 85 yards my poi the 282 gr round ball was at 1100fps...Good stuff!

With a harden round ball behind 110 gr 2f goex.this will cover most of the North American big game.

Do they make a double thick padded shooting vest????...LoL!

Impressed you took that "dump truck" up to 150 gr. WoW!

The hardened round ball has been proven up to the African big game...with much written....

Why the OP is bent on a conical has not been discussed.

Thanks for posting your results..hope you recovered..LoL!

Recovered from off side touching hair.
split on left rib entry..10 gr. total ball loss.
@ 60 yards left ctr mass down forward to right shoulder.

187 Lbs. zero body fat...split ball acted as a double ball load through lungs 2" apart made it to opposite hairline. Only shooting 95 gr. 2f Goex.
ruffed hair 4" from left shoulder blade was poi.

twig running through 1 of 2 split ball channels

You could do a lot worse than using the good old roundball?

Actually, yes you can do very very much worse.

An international expert on harvesting large, Dangerous game, James Forsyth, wrote a book in 1867, titled The Sporting Rifle and Its Projectiles. The fellow for which Forsyth Rifling is named, he did not like the Minnie ball for dangerous game, and far preferred the patched, round ball. His practical experience showed that the patched round ball outperformed the Minnie.

I might also add, for any hunting situation. With the Minnie which was developed solely for the military in a load and shoot situation, or any conical bullet that is smaller than the bore ID at loading, they have a tendency to become unseated and creep down the barrel when carried around loaded all day.
With a patched round ball the patch is compressed between the ball and the bore to hold it in place, as well as to grip the rifling and provide spin.

Quite a few of the various designs of Lyman minie molds can work with the base plugs swapped out from one to the other. That way you can adjust powder charges and bullet weights to your best advantage.

Over the years the designs on the plug areas of the blocks were tweaked at the factory but the older ones will generally work.

Currently on the LEE Website they offer three .58 conical molds, and they don't offer any in their REAL bullets.

Thank you men! all of your answers are what I was looking for. Ive decided I'm gonna give patched roundballs a try. I am a hunting guide therefore I want a hole all the way through a hog that's my reasoning for a big heavy conical. Maybe I have overlooked the performance of a patched roundball. Thank you all for the advice

I love the looks of that
