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.

That is REALLY exciting Steve! Cant wait to see those babies perform!
Congrats on the innovation👍

Steve, for those of us using the 143 HH with RE23 and mag primers, what would be a different load combination using the Absolute Hammer? I have lots of Varget but not sure if that is where load development points too.
Second, how much farther out could these be seated for us with shallow SAAMI chambers?

Are you shooting the 280ai?

About 30 thou more room to seat out if your mag would allow it.

Yes, that is what our shot drops were last saturday at 1008y. Might be a bit better than that as we had a 5 moa right to left wind. If I calc in 10% of the wind hold into the drop it would be a bit better. I am good with where it is for now.
Oops. Left to right wind. So if I calc in 10% of the 5 moa left wind hold that would make the g7 bc .223.
