Introducing the Absolute Hammer

I read that before I bought them, but had to try. I loaded 59, 60, 61, 62 and 63 grains of the H100V. Would you move on up or just stick with the RL-26. Will be headed to Colorado in a month deer hunting/ long range shooting. Im sure it will be stable there. If not, I will have the ole trusty MOA 270wsm and 170g eol's
Before I hunted with it I would stretch the legs on that load and test it out at 500y or so, it seems you are right on the edge of stability with your 1;9 at 100yards.
 
Where did you get the temp sensitivity chart? Is there anything out there that has more powders?
Just one that I've found floating around out there. I know Hornady has some listed in their 4dof calculator too. Obviously those aren't going to be exact for every rifle and every situation, but it'll give you a pretty good idea.
 
Well I just shot a little. Loaded up some 123 ah with some newly aquired H100v. Dont know why with the rifle doing so well with RL-26.( 6.5x257 weatherby 1-9 twist) But you know...Any way loaded 59g H100v 3.400 col fed 215m. Pretty light load, but about a 3 inch group. Yuck. Upon further examination I discovered the bullets are key holing the target. Dont know why but I guess I will be pulling the rest of the ladder and just sticking with the RL-26. Buoght some superformance too...Why cant we just leave well enough alone?LOL
9" twist is definitely going to be an issue. Particularly as the temperature drops. There is a high likelihood that they will tumble on impact, if you can get them to fly. You might be able to run the 109g AH well. It is 8.75" twist. With enough vel from the wby I think this one will run and perform on game.

I am sure that we will be designing a bullet similar to the 121g HH for the 9" twist to try and get some weight. Although the 109g AH at wby vel will be very effective a long ways out. I'm guessing not far south of 4000 fps. I will have to run the numbers.

I will order some 109s. Thanks for the info

If you can make sense of that it is pretty cool. At 3000' elev it has a 500y max point blank range!
 
So it looks like Hybrid 100v is going to be the powder to beat in my 6.5 PRC, got up to 3424 fps at 58.2gr before I ran out of time to test. The ES and SD are high and groups are decent but showing some vertical stinging so I'm going to bump up to 58.5 to see if that flattens it out. Will also be trying the lee FCD that I picked up to see if it makes a difference.

Looking forward to your data

Here is the 1st of many Absolute Hammers to come. We will be designing and producing these from .172 cal all the way up. Introduction of bullets will be in the most popular calibers and common twist rates and working our way into the less common stuff. We will base our design work based on sales of our current line.

We set out to design this bullet to address the problem that we see with bullets of tight bore specifications that engraver further out onto the ogive resulting in poor bc performance. We came up with an ogive design that does not allow any engraving forward of the shoulder of the bullet. Just before the ogive reaches bore dia we put in a reverse PDR going into the first PDR drive band. For those that don't know PDR is Parabolic Drag Reduction, this is what we patented. Now there will be no difference from rifle to rifle in how much they distort the nose of the bullet. The only thing that can change is the configuration of engraving on the baring surface. So with this design you will likely not be able to reach the lands. Nor will you base to ogive measuring tools work as you are used to. They will set on the shoulder of the bullet.

We knew when we started the 1st prototype design that we would be seeing a reduction is engraving pressure. Boy were we surprised! We are getting 3320 fps with this 155g Absolute Hammer in our 27" 280ai with very comfortable pressure. 2950 fps is the highest vel that Hodgdon shows with a 150g bullet and the fastest that Nosler shows for a 150g is 3107. The highest vel they show for a 160g bullet is 2872 fps Hodgdon and 3045 fps Nosler. They are getting their vel using H1000 and 4831 burn rate powders. We were not able to find any pressure until we dropped down to rl16 powder. We have not experimented with many powders as we were just after accuracy and ballistic information. We are running about 10g more powder at this burn rate than Hodgdon data shows for a similar burn rate and bullet weight.

So to give you an idea, the Absolute Hammer will gain enough vel to make a 30-06 run sxs with a 300wm. Hodgdon data shows a 30-06 running a 180g bullet at 2850 fps on the top end and the 300wm running just shy of 3050 for a 180g bullet. Assuming we see the same increase in vel with the 30-06 as we see with the 280ai, this is truly a game changer. Magnum plus velocities from large rifle cartridges and ultramag plus velocities from magnum cartridges. Trust me we will be testing big magnums very soon. I am pretty sure we will be pushing the 3700 fps mark with a 200g bullet in the Remington Ultramag. I will update on this asap.

Here is a pic, let me know what you think.

Looks a lot like a 6.5creedmoor cartridge am I right
 
Are the units on the temp stability table backwards, in that it should be fps/degree to indicate a lower number is more temp stable?
