Berger .257" 135 LR Hyb

Recommended Posts

I give them a thumbs up!  Got a few boxes to test out, and they sure look promising.  I literally found CBTO to lands, and backed them off .010".  Loaded up 5 charge weights just to see what they might do.  

Cleaned the barrel since I have about 150 rounds down it since the last cleaning, I am using a new bullet....and I have a pronghorn hunt in 5 weeks anyway, so good time to clean and refoul it.

I usually shoot both the 131 Blackjack Ace @ 3188fps or the 121 Hammer Hunter at 3414fps.  Both shoot amazingly well.

 

Rifle specs:

Kelbly Atlas Tac SA mag bolt face

26" 1:7.5" Proof Sendero (w. About 300 rounds down it)

TBAC Ultra 9

Manners EH1 w. Gen 1 mini chassis 

TriggerTech Diamond @ 7oz

Accurate WSM mags

ARC M10 36mm low rings 

MK Machine level 

ZCO 4-20x50 MPCT1 MIL/MIL

 

Load info:

ADG virgin 25SST brass

CCI BR2

54.0 to 56.0gr RL23 

135 Berger LR Hybrid

3111fps to 3205fps with no signs of pressure

No adjustment to scope, shots 4-6 (54.5gr) down the freshly cleaned barrel @ 3124, 3126, 3127fps.

The other loads were all under .4", even in the winds that were going on yesterday.  Going to load up the mild 54.5gr charge weight and call it good for now.  Hopefully put one in a pronghorn in August.

Yeah that will work..I'm still waiting for pre ordered ones to ship.  Why didn't you try H1000 or n565??

Lance, does anyone have these in stock?  I was in for preorder and actually prepaid for Blackjacks and nothing. Getting anxious as the reamer finally shipped to the smith. Still waiting for MPA to ship the chassis, but it may not matter if I have not ammo.  🙄

I have 24# of RL23....

I actually shoot H1000 with the 131 BJ and 121 HH.  

I use N565 in my 6.5SSs with heavier bullets like 144, 150, 156s.

Not that I have seen.  I am on numerous wait lists, and have 2k of the 131 BJs paid for already, just waiting on Sierra to hurry TF up and produce them!

Pretty awesome load. How do you like that ZC scope? 

Love the ZCOs.  I have two of them.  Both the 4-20×50s.  On my 25SST and 28 Nosler.
