I am trying find an equivalent bullet in the handbooks.

I don't see any similar profiles at 124 gr in any of the Lyman books I have. I agree about the bevel base
It appears to be lead
The bevel just makes it easier to start the bullet in the case and not shave off any lead. What brand is it?
What would like to know about it and all it's close relatives??

You found it !!
That is a sweet looking design, should work out well going up the ramp and into the chamber.
Any of the fast to medium powders should work with that lead bullet............ a nice target load should be around 980 fps with a starting load of Bullseye ,RedDot or Unique.
Enjoy.

well actually its only 92% lead, but I'll concede the point based on experiencing a good chuckle.
The bullet is made by Alpha Bravo, kinda local - they are up in Hanover, PA. He uses Magma Engineering moulds, and their website says this bullet is similar to a H&G 115 mould. That info hasn't helped any so far.
I want to establish load ranges for this bullet using 231, Bullseye, Power Pistol and Unique.
This bullet showed me that my loading experience has been limited to only 3 types of bullets, Hornady XTP, lead SWC's for 357, 38 special, 45ACP and 38 special wadcutters for a Model 52. For all of these, the seating depth or OAL was given explicitly - so I've felt confident that the load data I used pertained to each specific bullet and the charge range considered case volume.
So I guess I need to learn how to extrapolate and interpolate between load data charts, when a bullet doesn't match the books neatly.
Unless someone has data for this bullet.
Either way I want to understand what I'm doing - not just following a recipe.
I am loading this for a S&W Model 59 and regardless of the OAL (dummies made ranged from 1.112" to 1.161") all passed the plunk test, fit in the mag fine, chambered fine and ejected fine. But that's a 5% case volume difference. I plan on seating the bullet with an OAL of about 1.13" - that will leave the case mouth about 0.02" below the shoulder of the bullet.
When I look at the closest profile in my Lyman Cast Bullet Handbook, I see a 124 gr bullet (RCBS #9mm-124-CN) and the handbook gives an OAL of 1.050" for that bullet. That's a 7% case volume difference between 1.13" and 1.050". I think this roundnose has more weight up in the nose then the conical nose - so I'd assume the RCBS bullet is a little longer and will have even less case volume, so would the listed charges be too low for the roundnose? The whole range only varies 0.4 grains from starting load to max load!!

Looks similar to Missouri Bullet Co. Round

You are right on with your statements. OAL will vary all over the place with manuals, web sites. Use your barrel as a guide. Even popular bullets like Missouri there are no definite load data in a manual.
Just seat it to just were a tiny edge of the driving band shows. Maybe a fingernail width. Mild taper crimp. Check with the "plunk test" If all is well then load a few up say 10 or so and give them a test.
Load with the start load to mid range load of 231, Power Pistol or Unique I do not like BE in the 9mm but folks use it.
9mm is a high pressure round so medium to medium slow powders work best.
At the start load as long as it cycles the gun the brass should fall pretty close to you. Just as a suggestion from the info you gave me on the gun, Go to the Wolff Springs web site and get a new recoil spring and mag spring. They are cheap and you will be starting with a new gun. You do not know how old or how many rounds are on that spring.

While OAL is important in getting the round to cycle it is more important, to me, to be sure I am not compressing the powder charge. As I am working up a load I will put a charge in the case and measure the free space in the case. This allows me to calculate a starting OAL without compressing the powder. Depending on the bullet weight and profile I have run from 1.050 to 1.155 with no problems. Fortunately my XD's aren't too picky on OAL. Also don't forget to chamber check the rounds.

If in doubt, ask the manufacturer for their recommended loads.
I have a few old Lyman molds no longer made. Lyman provided me some very nice loads. I doubt any of them approach a true "max". It helps that I only have 3 pistol powders: Unique, 2400, and HP-38.

Hodgdon lists a charge range of 3.9gr to 4.4gr W231/HP-38 under a 125gr lead bullet in the 9mm. I charge 4.0gr W231 under any 124/125gr lead bullet in the 9mm and all shoot well. You might be over thinking this one...

So I happened to be near Dillon yesterday and stopped in. They actually had primers and 1000 S&S Casting 124gr round nose lead bullets. Bought them and now I will be reloading them. Guess I got lucky. I have a couple of pounds of HP-38 so we'll see how it goes. Haven't done the math yet for OAL and seating depth, probably this weekend. Always happy to add to the stock.

Here is my $0.02 but it's actually about $4.00. They seem similar to Missouri Bullets. I am using them in my CZ at an OVL of 1.05 and using ACCURATE #2, #5 and #7 and Ramshot True blue looks good which I don't have at the moment. My problem has been finding loads for 1.05" OVL.

I did ask manufacturer - he didn't have loading advice - he says they are very popular and gets quite a few re-orders

point taken!!
you have no idea how many times people have told me that over the many years - you've got me pegged
- and here's what I say in response - "its better then underthinking it" - or "I'm making up for a whole, whole bunch of people that don't think at all"anyway - I'll stop beating it into the ground and will just start loading and shooting

let me know how they shoot - your S&S Castings and the Missouri bullets don't have the shoulder that mine do

close--- but the missouri bullets don't have the same shoulder.
Lyman Cast Bullet Handbook has data for a 124 gr bullet (RCBS #9mm-124-CN) that has an OAL of 1.050" but not with your powders
I shoot several CZ's. The 9mm with the Missouri (parabellum)bullet needs to be real short to fit the chamber (leade) of the gun, Same with the Browning Hp in 9mm. Regular jacket bullets have a sharper point and can be a a longer length. Most of the lead round nose are short and chubby
So when seating for the above guns start at the very low powder charge as you are seating the bullet much deeper.
You SW should eat most anything.
PS: Have you loaded and dummy rounds of those things yet!!
They do not shoot just talking about them.

I have loaded 125gr lead RN from Western Nevada (Carson City)
at 4.8gr Unique for my CZ-85. A little smoky but still decently hot, and the CZ does like a hot round. Used both regular and Magnum primers in them.
I would actually go just a tad hotter with this load if I still had those bullets, but the only thing I could get was some 115gr lead, and ran out of Unique, so had to rework my loads with Titegroup.

That looks like a D&J bullet I have used for years in my 9's.
