45 cal cast bullet velocity

[ncsurveyor]

Realize its not too traditional, but the 22 twist underhammer I have supposedly tosses the 360 gr or 405 gr 45-70 bullets the best.

What would be an anticipated MV for these bullets using FFFg?

If three hens lay 5 eggs in two days, how long does it take a donkey to kick the seeds out of a watermelon?

OK, a little vague on the starting info, but basically looking for anyone with a measured velocity and what charge they may have used for a lubed 45 cal slug/conical from a fast twist barrel.

I really like that retort.....will have to remember it......Fred

Here are some targets with chronograph data. The barrel is a 1:30 twist Green Mountain .45. The first three are with 350 grain .451 conicals. The last two are with 465 grain .451 conicals. A 1/8" thick felt wad was used under the bullets.

Thanks, Semisane.

That is some tight shooting, and record keeping as well.

Do you mind if I make hardcopies of your pics, specifically the velocity data so I can crunch numbers in the comfort of my recliner later?

Go right ahead. So far as I'm concerned, anything posted on a public forum becomes public property. :wink:

Here is my info on a 409 gr bullet.

Don't fall for this one guys. It's a trick question. The watermelon is seedless.

 

[mooman76]

Even seedless watermelons still have seeds. :blah:

 

[Semisane]

If seedless watermelons have seeds, do feckless politicians have fecks?

 

[coloradoclyde]

Where do they get the seeds to plant seedless watermelons?????? :hmm: :haha:

 

[ncsurveyor]

pretty sure its aliens.

Thanks Idaho for the numbers as well.

 

[nkbj]

Just some more info.

 

[ncsurveyor]

thanks sir.
