Absolute Hammer load data

[GLTaylor]

Nice!! Now we need a 6mm and more 338's!

I'm planning to try the 172's when everything is put together. Like above, hoping to see velocity greater than 3000 FPS out of a 22" barrel. I went with the Defiance AntiX action in XM length to accomodate longer coal without having to go long action. Saved a couple ounces and 1/2" in rifle length. Hoping to see more data from folks using the Absolute Hammers in 7 Max.

My 6.5 Max is at the Smith's now. Hope to get it back late April/May. Plan to start with the 129 AHs. Will develop and post loads. If not fast enough, will go with 123s and see if I can make some lightning bolts!

Hammer 123 Absolute
24" Krieger 1:8
Going to go hotter with BLC2.
Interesting that my hammer 124 Hunters are @ 3177 FPS using 38gr of Superformance. If you look at velocity curve not getting much increase in speed even at 49.2.
It's just too slow. Will work with BLC2. Granular are much smaller than Superformance. Plus a lot more room in case ti work with.
Depending on accuracy I should be able tap into 3300-3400 range.
Stay tuned.
o! If you didn't notice 8 loads not 1 is .5 MOA+ ACCURATE!!!!

Zen, What rifle is that

 

[GLTaylor]

Yeah, didn't say what cartridge? If you want me to post this I need the rest of the data

I think you should get much higher velocities than this. I'm getting 3033 fps using the 124 gr Hunter and RL16 in my Creed. I will be trying the 123 gr Absolute with either 8208XBR or BL-C(2) in the near future

Custom build. 24" 1:8 Krieger Barrel.

What cartridge?

 

[cooperjd]

yes but in a ....? 6.5creed?

Ooops.... Yup

I'd be really interested to see if you can get 3,300. I was hoping for a safe 3,200, but blew a primer at 3,230, and have a "safe" max with IMR4166 at about 3,125-3,140 in my 24" tikka.

C'mon Zen. You know the drill...
Nk tension or crimp, OAL, primer type/size, etc......

Wait until I get my final load developed and I'll send you all the data. Got some hogs moving on the property I want to run them through!

Good for you! Go get em!
Don't forget photos

Pressure Test on 129 gr. Absolute in 6.5 PRC. As always your mileage will vary. Start low and work up.

Specifics:
Weather thin overcast with 55-58 degrees. Humidity was around 35%.

Tikka Action - modified for long cartridge operation
Barrel: Proof Research Carbon barrel w/7.5 twist and 22" length
Brass: ADG, sized with 0.288 bushing (no expander ball)
Primer: Federal 210 Std. Large Rifle
COAL: 2.955" - not that it really matters with this bullet

Process: I loaded up 2 casings with same amount of powder, then increased in half grain increments. The 59.0 grain loads may have been mildly compressed. The bullets were seated deeply with the first drive band just visible at the neck. I continued until the first signs of sticky bolt lift, then backed off one full grain and called it my Max load.

H4831 SC
Starting load: 55.0 gr. Ave. velocity 2,934 fps
Max load: 59.0 gr. Ave. velocity 3,095 fps *
* This was the highest load I had prepared. I did not reach any pressure cut off, so could have gone a little higher. No signs of pressure with 59.0 gr. of H4831 SC.

IMR 4451 (Close in burn rate to H4350)
Starting load: 56.0 gr. Ave. velocity 3,118 fps
Max load: 58.0 gr. Ave. velocity 3,255

I did shoot the 58.5 and 59.0 gr. loads as well. At 58.5 I got a big jump in velocity (3,317 average) indicating I was hitting the pressure ceiling. The 59.0 gr. load resulted in a very slight, but sticky bolt with ave. velocity of 3,326 indicating the max velocity curve was flattening out.
