I traded for an old Ohaus single cav. mould.
It is in excellent condition.
The owner said his alloy ( ACWW's ) cast at .4535 "
A VERY WELL MADE mould.
I plan to use this in my .45 Auto Rims in my Model 625 Smith.

Looks more than a little like the Lyman 452389 :

Nice, should shoot well for you.

I've got two very similar molds. The Lachmiller and a Lyman.

Lachmiller 200 gr

No picture of my own but the Lyman 200 gr.

Lyman 452460.jpg

I don't push either very hard and normally only lube 1 groove.

Nope, not at all. My Lyman 452374 is a single-cavity, and though the Randall eats them up most quickly, I'm as sane as I ever was. Just ask my wife.

Would love to have the mould in a 4 cav., but it is what it is.

I've got an old Ohaus #45 200 S that is almost a clone of the Lyman #452460. You can almost puts a #452460 into it's cavity, it's kind of amazing how many Ohaus, Lachmiller & Lyman molds are clones of each other.

No need to reinvent the wheel.
When a good design appears, it is only natural others will duplicate it.

At large, whereabouts unknown.
Many companies shamelessly copied each other others designs in the '50s & '60s. One would think that we would now have standardized universal mould handles, but noooo!

Saeco also has or had one super close [the 35-035?] it has that little wobble on the nose too.

JT showed me the single cavity he had, said his 1911 didn't feed it too well.
i told him he had 2 CNC machines 4' away from where we stood, put it in there and change the nose shape to a cone.
i even drew him a picture.

"Sanity" is hard to define, and in any event is greatly over-rated.

Ben's mould cavity looks like a wadcutter trying to sprout a round-nose. The closest pattern I have to this design is the Lyman #452460, which shoots wonderfully in both rollers and sliders. Like Rick said, up to 1000 FPS one filled lube groove suffices.

I bet most of the reason that a lot of 200 grain .45ACP bullets look so similar is simply a result of the weight and intended purpose of the bullet. The weight limits the body length and where the nose hits the feed ramp on a 1911 determines to a large extent the nose shape/size. After that it's just a matter of one groove or two, square shoulder vs more rounded edges, etc. It's just working within the engineering design constraints.

Yes, Keith......I'm in full agreement with what you've said.
I got outside and cast with the mould today.
I'm super pleased.
I can't wait to get some of these loaded in my .45 Auto Rim cases.
Then they will be shot in my Smith Model 625 revolver.

Ben, I’ve got a 5” M625 and it’s the most accurate revolver I own - and it’s a hoot to shoot. Haven’t found any bullet it won’t shoot well.

Your bullets look great, bet they’ll do just fine for you. Have fun!

As always Ben, beautiful bullets. It actually looks better as cast than it does just looking at the mold. should shoot well, I would think.
