I like the TC design for semi-auto bullets, and no one seems to have a light weight bullet in .45 cal of that design.

Mountain Molds has and online program that allows you to design your own bullet, and for a custom mold their prices are reasonable..I think!

Here is a 170 grn .45 bullet I drew, using their program.

I've had good luck with him in the past.
He can be a little "growly" typical of
most artists especially if you try to ask
him to do something that isn't part of the
set program he has. He prefers people to
just use his design program and order and
he makes the mold and sends it out without
him ever having to make contact with the
customer by email, his forum, phone, or
text. He does have some very interesting
legacy information on using pressure trace
equipment posted on his forum which is
definitely worth looking at if you are
interested in that.

His primary competitor (at least in my
view) is AccurateMolds.com who does not
have a design program but rather has a
massive catalog of every custom design he
has made so far with a note field to allow
custom changes to the design to be
specified by the customer. And for a lot
of things he will usually have a design
that is at least close enough to what one
wants to just select it and specify some
minor changes in the notes field. If on
the other hand if he doesn't have anything
close to what you are looking for in his
catalog already you just email or snail
mail him a drawing and or description of
what you want and so long as it isn't
outside the limits of his tooling process
he will draw it up and add it to his
catalog for you.

Both have their strong points, since I
prefer tumble lube molds I order from
accurate molds more then mountain molds
but mountain molds is very useful for his
standardized spitzer (pointed nose) high
velocity designs for 7mm and 30-cal
rifles. And he is at least willing to
consider smaller caliber designs that have
a groove diameter of less then .25"
although he probably isn't taking orders
yet. Where as accurate molds has set a
hard limit and will not consider cutting
anything smaller then what he can cut with
0.25" width standardized off the shelf CNC
internal thread cutting tools (he uses CNC
to use the tip of the thread cutting tool
to trace out the body shape you want)
combined with a standard off the shelf
0.18" boring bar to finish out the nose
profile down to a minimum flat meplat of
0.18" (the boring bar size). I believe
that mountain molds is using the same
technique but to my knowledge has never
confirmed it publicly as accurate molds
has. The point is though that mountain
molds is willing to consider dropping down
to a narrower body cutting tool to allow
custom 6mm and 22-cal molds and also to
use a pointed spitzer nose cutting tool to
provide that nose shape rather then just
the basic minimum 0.18" flat meplat on the
nose.

So far with mountain molds the spitzer
nose shapes are only available as fixed
canned designs for 7mm and 30-cal but
hopefully sometime in the future he will
offer them as a fixed nose shape option in
his drop down menu that locks the nose
into the shape his custom spitzer nose cut
tool makes but still allows the customer
to adjust everything under the nose tip
profile to their liking. I also look
forward to possibly some point in the
future the 6mm and 22-cal options showing
up without the R&D labeling indicating he
is mainlining those smaller diameter
onions, he will probably have to limit the
body length though to account for the
thinner toolings greater flexibility. At
that point there would be no reason not to
add 25-cal, 6.5mm, and 270-cal/6.8mm
options as well where he could fill all
the sub-7mm sizes that with the tooling
limitiations accurate molds has locked
down they won't be able to fullfill.

Turbo

I would like to hear a bit about your tumble lube experiences.

I shoot a lot of as cast tumble lubed .38 spl and .45ACP loads. I have had mixed results, with higher velocity loadings. I use the formula with liquid alox, mineral spirits and Johnson's paste wax.

Another source of molds is Noe.

I just checked through the Accurate Molds catalog, and there is my bullet..

Turbo I've used alox for years but powder coating is
faster and cheap you can run a lot hotter and no leading
