Help ID this Unknown 150gr 7mm Bullet

[ojibweindian]

Does anyone know anything about this bullet? All I know is that it's a 150 grain 0.284" SP bullet. Would like to know who made this, and maybe find out its BC.

Thanks in advance!@

Looks like it could be a Remington Core-Lokt given that it has a cannelure and flat base.

Hornady has a similar bullet SP, flat base, with cannelure but it's 154g.

If it's a Core-Lokt, it's not like any other I've seen. If you look just above the cannelure, you'll see a ring. That ring isn't present on the Core-Lokts I've loaded up.

That ring looks to me like a seating die pushing on the ogive, but now that i look at it again it looks to far back for that to be the case.

Agreed.

I bought 1K of these well over a decade ago from Midway; one of their "blemished bullet" deals. Scoured the 'net for years trying to figure out who made these and have never been able to find anything.

Well if you have a chronograph you can determine the BC of the bullet. Get your muzzle velocity and then setup your chronograph at 100m and get your velocity there.

Then you can find your air density/resistance and use the formula on this page:

Looks like a Hirtenberger or RWS. They used that funny extra lock ring forward of the cannelure. Odd that it's an even grain weight though. European bullets usually come out at odd numbers when you convert the grams to grains.

Profile is close enough to 150 Core Lokt to just use that BC for most shooting. I wouldn't worry about any sort of long range precision with a one-off unknown bullet.

No cannelure.

That second ring looks a lot like the mark my RCBS collet puller leaves behind.

No cannelure.

That is optional on a lot of bullets including smks.

You sure they aren't pulled bullets? That might be the reason they were seconds. Used in the wrong application and pulled for that reason.

Older Hornady .308” 180gr Spts looked just like that. (Cannelure and ring). Check the weight. I’d bet they’re 154gr Hornady Spts.
They could be Hornady 150’s made on contract for some small ammo company.

re: B.C.
It would be safe to use the BC for a Hornady 154gr Interlok

I’ve got a bunch of 7mm bullets that look just like that. I can assure you mine came from Hornady. Indeed, they were seconds. Don’t recall whether they are 150 or 154. Might even be in the 130 gr. range instead of the 150s. My best guess is Hornady.
