Introducing the Absolute Hammer

[jebel]

Just did some pressure/velocity testing in the yard of the 123 AH. My current load is the 124 HH with 56.55 grains R23.

You got 3,201 fps with the AH and 56.55 gr R23. Curious what your typical velocity with the HH was with this same charge. Similar?

Thx

215M in all my bees.

What are your thoughts on rl-33 and 123 ahs? Have not seen that combo brought up on this thread.

3256 - 3322 with the HH. Here what I have in my spreadsheet. I have more in my book but this are the relevant ones.

56.4 3249 61 deg.
56.55 3256 36 deg., 8 shots, SD11, ES26
56.55 3322 81 deg., .25", 4 shots, SD6.9, ES15 (this was high pressure although it produced the attached pic)
56.7 3247 61 deg.

Just ran the saum and here is what I got so far.
Rl16 59gr max 3395fps
Rl22 62.5 max 3404fps
I only have about 6 more powders to try.

62 gr of rl22 is just slightly compressed. 3387 average 12 sd
5/8 inch group
I'm obviously on the wrong powder still because this velocity is slow.

Try Superformance or 4831sc

What was your velocity with the Hammer Hunter? Your SAUM case is basically the same as my Sherman Short and I got about 110 fps faster from a high pressure HH load to a low pressure AH load. Talking with Steve it seems that's about right.

 

[25WSM]

Haven't shot any other hammers in it. Been shooting 140 hybrids and 147eldm and they go right at 3200 with rl26.

I would think I could shoot 3400 with a conventional bullet from it no problem.

Went out today to get some testing done with the .264 123gr AH and here are the results:
COAL was 3.042 and could have brought it out to 3.099. Used H100 Hybrid V. 6.5x284
26 inch barrel, CCI250 primers, new LAPUA brass.
51.9GR - 3162FPS
52.2GR - 3178FPS SD7 ES14
52.5GR - 3184FPS
52.8GR - 3239FPS SD11 ES22
53.1GR - 3241FPS
53.4GR - 3253FPS
53.7GR - 3274FPS
I actually had 2 loads (2nd and 4th) which were sub moa. Not much pressure as I believe had I not
seated the bullet so far in I would have been able to achieve 3300 easily with additional powder.

Great info.
Looks like HV100 may not be fast enough. I'm wondering if Varget may be the answer.

Probably can get more speed running coal at 3.090 and adding more powder. I actually should have had it there. Undoubtedly it will reach 3300 and beyond.

 

[cohunt]

Might look at some of the powders in the reload section of the gscustom bullets page you get some ideas to try--- those bullets tend to like "fast for caliber" powders also

Well, I look forward to your report. I'd like to run these bullets in my 6.5-284
