Gavin Dinghams 44 mould - Don McDowell - 04-16-2013
I think our 44 fanatic from down under might have hit a home run when he had Accurate come up with this 44-400B bullet. I think it may work like a champ for a light greaser for hunting or target work.

I like the nose diameter of .433 for a Shiloh. Wondering if two lube grooves will get the job done? Guess they do though!

Nice picture. Did you take that, Don?
Wonder how the design would work for .45 cal.

Gary no that's the picture Gavin took and posted on his Photobucket so we could see it.I think if you look there's already a 45 of real similar design there.
Here's his disrciption of it as cast in the picture.
Overall length is 1.097" ..or close enough to 1.1"
..as cast is .447 diameter ..base , second and third driving band.
..the top band with the taper to the nose..is also .447" but only for about .015"..then it tapers off quickly to the nose which is running at .433 for approximately 1/4" inch before the ogive and finishing at a meplat of .2".

Do we know the weight of the bullet on the right?

RE: Gavin Dinghams 44 mould - Don McDowell - 04-16-2013

RE: Gavin Dinghams 44 mould - powderburner - 04-16-2013

Man Don @ .433 it will have a lot of slop ahead of the case mouth and when it gets pushed in the hinder when the charge gets lit up there might be a lot of weird things going on as it flies down range???
But it will make a good bullet for shooting dirty.

We'll know more about the thing and how it shoots when Mike gets his blocks in a couple weeks.
