Berger 6.5mm 153.5gr Hybrid Bullet

[Stumpm2]

Does anybody have any experience/results from the Berger 6.5mm 153.5gr Hybrid bullet? Looking for comparisons to the 156grain EOL. Thanks.

As far as accuracy results, they work very well for me:



Is this the kink of experience/results you were thinking of?

Thanks. They look to be pretty forgiving from your data. Any terminal performance?

Out of my 26" bull barrel, they've performed quite well at around 2920 fps with my RL23 load as well as with 56.3 gr of Retumbo at the same velocity. My ballistics app shows down range velocity at 1200 yds. at 1586 fps; at 1000 yds., need ~247" elevation.

How do they compare in OAL compared to the 156 grain with the same jump?

Since there really no relationship for OAL to jump, I assume you're actually interested in the difference in their BTO???

Berger's published BTO:
153.5 = .826"
156 = .809"

Berger's published Bearing Surface:
153.5 = .560"
156 = .545"

Berger's published OAL:
153.5 = 1.514"
156 = 1.512"

Doing some math taking into account the other variations . . . my loads have a seating depth of .478". If I seat 156's to the same exact seating depth, they'd be ~.019" farther from the lands than the 153.5's. And the MV's for the 156's at that seating depth is ~ 20-25 fps slower. That longer bearing surface of the 153.5 suggests to me that it tends to be more stable than the 156's.

Of course, one would have to take the variations into account that occurs from lot to lot for each.

I have a Bergara Premier, I shot the 156 when my rifle had the factory bbl, and I seated to magazine depth. {I'm not as detail organized as Staightshooter} Behind 56grs of N565 3,000FPS and 3/4 MOA was easily achieved. Now with a 28" Bart HV contour, the 153.5 with the same magazine seating depth and load, 3125FPS, and 1/2 MOA is easily produced.

I'm shooting them in a Savage Desert Tactical 24" barrel, it shoots this load consistently right at .5, 58.1 N565, 2990 fps. Bullets are seated to just fit inside an AICS mag. Shot a cow elk at 360, she went 35-40 yards and died quickly. I found most of the bullet (pieces) just inside the hide on the offside.

What length barrel and speed are you getting with running the 153's? I've stayed in the 140 class of bullets with my creed. But this is very interesting!

Ruger American 22”, running 2530. We’ve ran them up to 2620 out of that barrel, but it really likes the node at 2530

May have to look into these as well. Currently using a 143 grain pill but wanting a little more weight for our big bodied mule deer this fall.
