Introducing the Absolute Hammer

[northhunter]

I noticed my COAL is longer than all the other loads in the spreadsheet. Could that be why we can't reach the same speeds as your testing produced? Along with the Nosler brass I suppose. I am really new to reloading and was reading about being seated closer to the rifling causes higher pressures and further reduces pressures but also reduces speed. We are loading to max for my magazine but still have 0.080" jump. I tried to look at some charts posted on this subject, but it appears Hornady removed them from their site. Does anyone know where I can find more info on this?

The jump for the Absolute Hammers is largely irrelevant as there is no ogive like on a standard bullet. People either load them as long as the magazine allows for the extra powder space or they load them short so that all the grooves are in the case mouth.

If I'd guess I would say the Nosler brass is the difference as it is typically much softer than ADG.

 

[northhunter]

Thanks. I will try and get some ADG or Lapua when I can.

Referencing back to a post Iby @ButterBean, you could try seating down into the case until you are about to compress the powder charge, or you get the first PDR band into the case mouth.

I haven't measured a COAL dice I started loading Hammers I have not ever had to adjust anything, I seat as deep as I can, the first PDR groove if I can get to it, I know a few folks have had to adjust to get a good group but I have not

Hammer Hunter Seating Depth

What are you guys seating your Hammer Hunters to? I've seen everything from SAAMI COAL to 0.020-0.030 off the lands.

A friend of mine has been doing my load development for me with some minor input from myself. He have found a really nice node with 4831sc. He did a ten shot ladder. Here are the results:
Christensen Arms Mesa 6.5 prc 1:8 twist
Nosler brass (he annealed it) CCI 200 primers
123 Absolute Hammers. COAL 2.969, 0.080 jump
4831sc
53.5. 3005fps
53.8. 3013fps
54.1. 3031fps
54.4. 3042fps
54.7. 3086fps
55. 3080fps
55.3. 3030fps
55.6. 3050fps
55.9. 3089fps
56.2. 3117fps heavy bolt lift

125 badlands have done quite well for me with h4831sc

This is what I settled on

I'm not stupid I know. These absolutes are touted to have high velocities and he's getting lower velocities with a lighter bullet same powder. Just sharing my data don't be so hurt butterball.

Not hurt at all Neighbor, Once again your in the wrong thread

 

[nicholasjohn]

Wouldn't my pressures get worse with faster burning powders though?

The relieved bearing surface in the bullet shank requires a slightly faster-burning powder to get the highest velocities. With the powders of the burning rate you might use with other bullets of the same weight & diameter, and the usual charge weights for your cartridge, you would probably get low pressures & velocities. Past experience with monolithic bullets with relief grooves in the shank have shown me that the rifle will digest pretty stiff loads without showing pressure signs, but as you work up incrementally, you may find that this changes rather suddenly. This tendency may also be exacerbated by the faster powders, so be very cautious s you work your way up the scale, and consider using smaller incremental changes than what you might typically use. I haven't worked with this particular bullet, but a lot of guys on this forum have made comments similar to these. If you read a bunch of the posts about this, you will be well-informed on what t expect with these bullets. You can also call Hammer Bullets and get some intel on the loading & testing process.

I guess real world data didn't meet expected inflated results

 

[nealm66]

Lol, wow. C'mon guys, we're all here to learn and share knowledge and experiences good and bad. Nobody's getting commission for saying they're getting good results from these new bullets. They do act differently and I've had really good luck so far. Will be doing load work up on a 270 wsm with the 116's this Friday and pretty excited about it.

So my real world data with the AH is 200 fps faster than your badlands data using a faster powder, how is that inflated? Also the requirement to use a faster powder has been repeated pretty much from the beginning so it's not like it's new info. Heck I personally determined it myself last September back on post# 566.

I am running the 123gr AH and since it was said that the AH needs a faster powder I tried H4350, StaBall 6.5 and H4831SC (per Hodgdon burn chart numbers 124, 129 & 137 respectively) to find the burn rate sweet spot and see which would provide the best velocity before reaching pressure. H4350 topped out at 3245, StaBall topped out at 3370 and H4831SC topped out at 3220 using new ADG brass for consistency.

So are you just here to complain about the perceived inflated results or have you actually tried them yourself?

Not the same powder so no care and you do know that it's not even max charge right?

Let's compare apples to apples not apples to oranges

good try though

 

[Jonoton]

In keeping with the produce theme, you wish to compare unknown varieties of apples to other unknown varieties of apples.
You didn't post your own barrel length, the post you quoted does not have a barrel length. Etc.
