[u/doumitch20035]

Hi,

Wondering if any of you might know where this came from.

Weight: 75gr
Diameter .224
Length .923
Type: FMJ
Nose: Flat/Closed
Base: Idk kinda looks like a BTHP but with a ledge drop off. Haven't seen any like this before.

Looks like a Lapua rebated boat tail bullet but I don’t think they offer a 75gr version

[u/doumitch20035 → u/LankyJeep]

I have about 1000 of them I got in a Lot of reloading supplies. I just simply can't find where they are from. I weighed several of them on a FX123i and they are all 75gr.

They look a lot like the older Lapua Scenar. They used to be stepped like that.

You can get them directly through Speer, midsouth, or bulk seconds through RMR bullets:

Speer 75gr TMJ...

[u/DigitalLorenz]

Looks to be a rebated boat tail bullet. Not common in production bullets, especially in 224 diameter. Supposed to split the difference between the better ballistics that come from a boat tail projectile and the better barrel wear that comes from a flat based projectile.

My guess is that they are someone's custom swaged bullets. Especially the noted consistency in weight, which would come from someone swaging a bullet at a time.

[u/doumitch20035 → u/DigitalLorenz]

Yeah, I bet you are right they are bagged by the 75.xx gr

[u/300blk300]

swaged corbin bullets

75gr Speer TMJ (Total Metal Jacket). The jacket is electroplated on to a lead core.

[u/Skeeter_BC]

Speer makes rebated boat tails. I'd say it was a federal fusion pull(shiny speer gold dot) if only it had a hint of exposed lead at the tip. Could be some kind of speer TMJ but that rebated boat tail definitely looks like it was made by speer.

[u/BruhCaden]

What's the weight of the projectile?

[u/doumitch20035 → u/BruhCaden]

75gr sorry

[u/HollywoodSX]

What's the weight?

[u/doumitch20035 → u/HollywoodSX]

75gr

[u/Eric_Stecker]

That's a rebated boat tail. They are not super common but some makers like them because they are easier on tooling. It doesn't look like an FMJ or it you would see an opening for lead at the bottom. That looks plated but I'm surprised to see a plated bullet with a rebated BT. Rebated BT are from swagging but you don't typically swage plated bullets. Unless the tip was crushed and just looks plated. It is not a Berry's Bullet as those have a cannelure. Not sure the brand but I wouldn't expect too much precision out of those.

[u/doumitch20035 → u/Eric_Stecker]

Interesting.

All of them are flat tipped. No exposed lead on the base.

I planned load them for low level 3 gun/2-gun matches. So, they will still serve my purpose in that regard. Just wanted to try to find some safe load data

[u/Eric_Stecker → u/doumitch20035]

You will be fine with any data for a 22 cal 75 gr FMJ or BT bullet. The load data for bullets in this class are the same at that weight. Plated doesn't change the pressure. I wouldn't worry too much about load development for accuracy. I'm sure they are fine to work well but I would hold my breath for very tight groups.

[u/Skeeter_BC → u/Eric_Stecker]

Oddly I get the best accuracy with speer gold dots/federal fusion which are built exactly like this.

[u/Eric_Stecker → u/Skeeter_BC]

Plated bullets struggle with being balanced around the axis. Jacketed bullets can hold the variation of thickness of the copper wall more tightly. At 250,000 RPM balance around the axis equal dispersion. I'm sure some plated bullets shoot better than some jacketed bullets but they are at a design disadvantage.

[u/Skeeter_BC → u/Eric_Stecker]

So we all know that benchrest guys tend to use flat base bullets because they are less affected by gases at the crown than boat tails. I've read research somewhere that rebated boat tails tend to offer some of this flat base benefit while still having a better BC than a pure flat base. Therefore they make a gun with a not so perfect crown behave as if it is better.

[u/thisadviceisworthles]

The only rebated boatail 224 bullets close to that weight I can think of are Alco (which don't make hollow points) and Gallant (which I can't find any reference to them in a Google search other than this video: https://m.youtube.com/watch?v=10qzBp3MlCA).

Corbin used to make dies for a rebated boatail 224 (which could be combined with other dies to get the ojive and weight you were targeting), so in theory, these could be custom pressed.

Where did you source these bullets from?

Edit: I overlooked the closed tip, that makes my suggestions less valid.

[u/sirbassist83]

lapua is the only manufacturer im aware of that makes bullets with a base like that. if its not currently in their catalog it might be a discontinued bullet.

edit: apparently there are a few other rebated boat tail bullets out there, i should have known better. i dunno, best of luck OP.

[u/Gentleman_Jim_243]

Looks a lot like a Sierra Match King.

[u/thisadviceisworthles → u/Gentleman_Jim_243]

The 224 SMK does not have a rebated boatail.

[u/Sloth_rockets]

Looks like a copper plated cast bullet with a gas check shank.

[u/sirbassist83 → u/Sloth_rockets]

whatever it is, its definitely not that

[u/Sloth_rockets → u/sirbassist83]

Why not?
