[ARCHIVED THREAD] - AAC SBBT 75gr and 62gr Chrono info, and groups

Posted: 6/25/2023 10:00:38 PM EDT

Made it to the range this AM, chrono'd some various rounds and shot groups.

ZERO function issues. 100% reliable.

The AAC / PSA Sabre Blade Black Tip bullets are similar in construction to the Sierra TMK.
This thread isn't about the SBBT's terminal performance. Ballistic gel tests concerning that are coming as/per Jamin w/ PSA

Rifle is a 20" 1n7.7 twist Krieger barrel. ( I consider this to be a "fast" barrel, so YMMV ) 100yds, Benched , bagged, scoped, etc.

The 75gr AAC SBBT ( lot # SCL2CF081 ) chrono'd at an average of 2704fps, ES of 39fps, SD of 11.0

The first 10rd group is great, I must have aligned all the Shooting Gods stars. Lol

Next 11rds..( oops ) still darned good for the price.

Next 9rds, again oops...

The AAC 62gr SBBT ( lot # SCL1CF062 ) chrono'd at an average of 2997fps, ES of 90fps, SD of 32.3

10rds

10rds... much more horizontal group, I will blame some of that on me.

All in all, I am quite happy with both. ESPECIALLY concerning the price. ( Thank You @JMan_JJE )

I will order more of the 75gr SBBT for sure, I like heavy for caliber 5.56 ammo.

From another forum.

JBoomhauer did a bullet cutdown ( in half ) with a Milling machine and an endmill. Sanded with some 3M superfine to remove burrs.

Can you describe what is in the picture and why it matters?

Not meant as a negative, just helpful to know for discussion purposes.

Have you shot any of the 77gr TMK loads at distance, like 600 yards?

Looking for ammo supply for juniors shooting CMP matches.

My bad, that shows the jacket thickness. The AAC 75gr SBBT has a thicker jacket than the Sierra TMK, he measured it as well.

Also, JBoomhauer's photos

That's a pretty good SD for the 75gr!

And glad to see it looks more like an ELD-X and not a VMAX bullet.

I'd be pretty confident using these guys on hogs/coyotes maybe medium game.

EDIT:

So I'm going to guess that ballistics gel tests might look like the 73gr critical defense like in these videos: https://youtu.be/Q0zFJ-kcm_g and https://youtu.be/mXjLcKa6lJc

This is only based on multiple speculations....that the Sabre is like and ELD-X and that the Critical Defense is basically the 75gr ELD-X but the tip cut off for OAL purposes resulting in it being 73gr.

I'd still pick a 75gr gold dot for a do-all round, but for $0.55cpr for predator ammo works fine for me.

Not true ballistic gel... but, still good performance to me.

Does Sabre BLADE Black Tip Cut the Mustard?....5.56 AR-15 Self-Defense AMMO Test!

Looks good so far. Short neck, good fragmentation, retained enough weight to get acceptable penetration (at least in clear gel)

I like that he tested at 28 yards instead of the 10ft that most people do. Now we just need to wait for some shots into organic gel

Velocity and SD #'s are encouraging in the YouTube video.

@bfoosh06

75gr Sabres on the left 2 targets, and 7-8rds of the 77TMK’s on the right target.

Rifle was one of my bolt guns. 26” 1:7twist, each group was fired at 100yds in about 20 seconds from a barricade. All groups were under MOA.
