Had a great day casting today! I recieved three custom molds from "Accurate molds" today!
This is the 525 grain Postell clones that I casted today. They were not sorted at the time of the picture, but I thought it looked right for a picture.



This bullet is a 420 grain, double crimping groove bullet. The extra groove compensates for the shorter Hornady brass I use occasionally.



This bullet is a design that Tom drew up for me to fit my browning Miruko 1885, BPCR in 45-70 Govt. If I seat this bullet to the bottom on the lower rounded lube groove, this bullet is firmly placed against the rifling and fills the throat of the chamber very well!



Here is a picture of my 525 Postell clone (actually 548 grains) on the left, and the 485 grain Hell Hammer (LOL),bullet on the right. The Hell Hammer is an experiment I am trying for my Browning 1885 BPCR. I think its gonna be fun!



Hope you like the pictures!

I like that 420 grain bullet, too. Plenty versatile. Would likely make a great hunting bullet in my 1886 Win. lever rifle. I understand these are custom molds...but, does Accurate list a catalogue number for this mold?
 
Had a quick look at the Accurate site. Might have answered my question, already. Is the 420 grain mold this one: 46-420H ?
 
Yes,that is the correct number for that mold.

After using the 4 cavity mould, I would not go past a 3 cavity mold. They are fairly heavy when full, and require me to re scoop three times to ensure enough lead is flooding the cavity. Other than that, they are awesome!
 
They look very nice. I shoot Lyman's nose pour 540 grain in my BPCR, but it pushes me around too much at the bench these days. I'll never sell it, but I use my. 38/55's more these days.
 
A bit of a thread update:

I tried trapping one of my cast, flat nosed Postell bullets today, and was successful this time! Yahoo!

- This bullet that I recovered started its journey at 546 grains, and ended its flight still weighing 530 grains! I am happy with that retention!

- velocity of this bullet was 1451 fps. (chronygraphed).

- Range was at 100 yards.

- medium was a 5 gallon pail full of muddy water laid length wise to the bullets flight path. Behind the pail was a 18" diameter spruce log.

- The bullet hit the pail well centered, and travelled the length of the pail (rupturing nearly the whole length of the pail), and was stopped in the spruce log with about 2.5" penetration.

- The mushroomed bullet diameter was 1.0195" ( I nipped off a small part of the rolled over part of the mushroomed skirt with the axe while extracting the bullet from the log).

With expansion like that, there may be some serious wound channels in that rifles future! I am so looking forward to try them!






In This picture, the mushroomed Postell bullet is flanked by two of its unfired clones, and is the same nearly pure lead alloy mixture.
