Absolute Hammer load data

[ButterBean]

OK thank you. the 4955 should burn close to H4831, though the case fill will differ. I do have a few lbs of H4831 on hand, no IMR4831 at the moment.

That will work but I'm gonna say it will be on the slower end, Let me know what numbers you get

COAL 2.275 ( seated to the last bearing groove)

Should this be COAL 3.275"?

And that's a screaming fast load!

Yep. I've got fat fingers

BBean, your keyboard is just too small. Can't be your fault these days...

Velocity results dictated that I skipped some of the loaded rounds I had to determine speeds/pressure.

What do you plan to try next?

 

[lejuch]

Probably just stick with the RL26 around 65.0 and various COAL to dial in the accuracy. Shouting results I listed were shot for velocity/powder info in my gun. I'm just assuming the rifle will shoot well ...from an accuracy standpoint

58 gave 1+ moa groups with the 18" and 1/2 moa groups in the 26" while 58.3 was the opposite. 58.6 gave sub 1/2 moa groups in both which is where I'm going to load them if I go with StaBall. I think I'm going to give Hybrid 100V a shot as I got them up to 3400 in the Proof barrel though they are definitely too hot when run through the X-Bolt.

For whatever it is worth, StaBall 6.5 and H100V are next to each other in burn rates, but the H100V is less temp stable.

Gotchya... didn't know if you were going to try some other powder combos or try to find where you pressured out with 4831.

Have you had any luck with the staball everything I tried it in got real wonky on the high end got some real good groups but they were always on the low end so I just quit trying it

I only have H100V, so haven't been able to try StaBall6.5. That being said, I used 61.5 grains under 140 gr. AH (3.355 COAL) and 57.5 grains under 155 gr AH (3.365 COAL) in my Savage AXIS II in 280AI this past fall for a deer/elk combo hunt in Montana. Used the 155 on a decent mule deer buck. One shot, bang, flop, DRT. Also took my Bergara 300WM loaded with 178 AH over 76.0 grains of the same powder, H100V. Same results on a cow elk, one shot, bang, flop, DRT. Really impressed with Hammer bullets. Been shooting Barnes TSX for a decade or more but never had results like that. Most elk took two shots with the Barnes. Wasn't worried about the temp sensitivity in the H100V due to cold weather in Montana. I've only had issues with 85 degree plus temps.

I really like the 100v it fits really well in alot of different cartridges and alot more of them if you are using the absolute hammers and great fps

It spikes with a .2gr change in your load, Everything is fine to a blown primer that quick it does work great in my 25-06AI but was slow in my 270AI
