Very nice GroovyJ...very clean castings too.
What odds Gelan will take one look at these and say..."I want a mould !" I can't say I blame him...they look lethal mate.
Cheers, Vince

I can't wait to hear the shooting report on that one. What is the twist rate in your barrel and the length of the bullet?

14"twist should be ample for that HUGE pellet!!.
I imagine the lead pot would empty very fast while casting these babies
Is that an aluminum mould?
the cavities looks HUGE!!

Gelan, I don't think that big boy would work in a .45-70...

According to the Greenhill formula a 1-in-18" twist should be fast enough for velocities under 2000 ft/sec. 1-in-22" for velocities over 2000 ft/sec. Another way to look at it is that a 1-in-14" twist should stabilize bullets up to 2.25" long.
My .45-70 Marlins have a 1-in-20" but the Pedersoli "Remington" rolling block has a 1-in-18" twist... Hmmmm!

I have the Greenhill chart too , and without looking 14 will stabilize 864 grains in .457 bore , I believe .. My charts dont have one for velocity , only length and weight ..
Theres a formula which isnt to complicated to use if you dont have the chart ..

Maybe! But you should not stop dreaming just because!
I have shot a few 600 gn of my H&R Buff classic,
not great result but should be doable for close distances.
BTW, a Buff Classics is 1:20 twist
That alone should stop me from trying something like groovies bullet.
