Absolute Hammer load data

[dougduey]

Has anyone tried a 151 AH in a short barreled 308 win. I am currently shooting the 152 HH with 44.6 grains of IMR4320. Very accurate but I haven't chrono the load yet. Today I ordered the 151 AH for it. Should I be trying TAC for a faster powder than IMR4320. Varget I'm sure isn't fast enough so I'm checking the charts for a good starting point. I have a 20" barrel on my Rem 700 Police. Currently shooting 168 ELD-M Match ammo at 2644 fps. I have a hunch the Absolute Hammer bullets are going to make me shelf these rounds. Thanks.

I would try IMR8208XBR. Heck, Benchmark may work real well for you, too.

You must have some very tolerant neighbors across the street! :>)

His neighbors are rows of corn

I have some H4895 and IMR 3031 on hand.

The 3031 will probably be a tick fast but I think it will work and the Tac as well

In my short .308 win, TAC has been magic with 125gr class 'conventional' bullets. I'd bet thats a very good suggestion for the 152AH.

Ahahahahahaha

Whatever your results, don't forget to post bullet, brass, neck tension,,primer, powder charges, velocities and remarks. Others benefit when I post the data,!

Will do!

No luck finding IMR8208 or TAC anywhere. I did find 2 lbs of Benchmark and 2 lbs of StaBall 6.5 for my 300 win mag and the 178 AH. So Benchmark it is for short 308. Hopefully my bullets get here next week.

Here's some data for my 7mm STW and 6.5 SAUM shot yesterday. Conditions were 65F at 0 altitude.
Labradar Chronograph

7mm STW
9 twist 26" barrel.
140gr Absolute Hammers COAL 3.65 (magazine length) .004 neck tension
CCI 250
Nosler brass
RL 26

80gr 3397 fps
81gr 3458 fps
82gr 3545 fps
83gr 3569 fps
84gr 3633 fps very faint ejector mark
85gr 3671 fps sl heavy bolt lift and sl ejector mark

Probably will go with 83gr, no pressure, 4 shots gave 3569, 3572, 3577, 3581 .5 MOA accuracy



6.5 SAUM
8 twist 24" barrel
120gr Absolute Hammers at 2.925 COAL ( Puts shank of bullet at shoulder of brass. I did this with the 181HH in my 300WM rather than trying a certain bullet jump and got more consistent grouping and velocities )
.003 neck tension
CCI 250
ADG brass
RL 26

61gr 3146 fps
62gr ......
63gr ......
64gr 3303 fps
65gr 3351 fps
66gr 3420 fps
67gr 3497 fps
68gr 3510 fps heavy bolt lift, no ejector mark, POI out of the group

Settled on 66.8gr 3470, 3477, 3482, 3475, 3480, 3476 less than .5 MOA even out to 500yds

Both loads may get tweaked a little based on long range accuracy but are very promising.

Thank you. Good work.

Shot the 151 AHs for the first time this morning using IMR8208XBR. Loaded up 1 round each in 0.5 gr steps from 43-47.5 gr. Brass was sized with Redding dies with expander removed. Measured 0.006 neck tension. Temperature was 37 deg. Velocity recorded on CD ProCronoDLX.

Start Low and work up on charge weight!

Winchester M70 FTW SS - 308Win
22in Factory 1in12 twist
Lapua Brass - Trimmed 2.006
Fed 215
COAL - 2.863

1) 43.0 - Did not record
2) 43.5 - 2711
3) 44.0 - 2791
4) 44.5 - 2786
5) 45.0 - 2842
6) 45.5 - 2861
7) 46.0 - 2882
8) 46.5 - 2929
9) 47.0 - 2951
10) 47.5 - 2971

Never saw any signs of pressure. Shots 7,8, and 9 are touching. May load up a few more but 47.5 is right where the load starts compressing for me so I'm not sure how much more I can load before it starts pushing the bullet back out. Will probably load a couple up and let them sit for a few days and see if the COAL changes. Was able to pick up a lb of Benchmark so will load up a similar ladder and see if I can get a little bit higher velocities.

Looks like 8208XBR isn't fast enough if you didn't find pressure. So, Benchmark may be the answer since it's a faster powder. Keep us updated.
