They kill great, kinda like monolithic partition the front expands on impact and the petals shear off internally and the shank penetrates on through the faster you run them the better they work

Suggest you go to the Hammer Bullet Load Data thread and look at the info there. It's at post #2. You will be amazed. Now these are all the Absolute Hammers. Regular Hammer Hunters or Shock Hammers follow more conventional powder loadings and use standard powder burn rates.
Looked it up. WOW! Butterbean is my hero! Lol That's impressive indeed.
You will love them, If you need any help just hollar, when you order your bullets tell Steve ButterBean sent you

10.25 twist would not stabilize the 181s in .308. May be a little better at higher elevation, but would not risk being marginal at this point anymore. Definitely look to overspin if anything.
Butterbean and WSM have done some amazing work. A fellow from Australia has also gotten some crazy speeds
I agree with this but all hammers load differently, the have there own set of rules, With that being said load development is simple

Seems like they prefer faster powders for bullet weight from what I'm reading. If this is the case, how did you determine which powders? If they act differently than published data is there a trick to powder selection?
The AH do need a faster powder, If your loading 115g look at the 100g data, 100g-85g and so on, If your loading the HH look at the book max for what ever your loading drop down one grain and work up from there until you find pressure, drop 1/2 grain and let it eat
Gotcha. Thanks!
It takes about 10 rounds to find your load with the HH's
Absolutes require experimentation.
Get a copy of the powder burn rate chart. For regular Hammers, start with recommended powders for a given wt bullet. If you don't get desired speed, go to a faster powder by a couple of speeds. Work up again.til you find the sweet spot.
For Absolutes, refer to the Absolute load charts on post #2. A bunch of us have done most of the leg work for you. A bunch of powder has been burned in the learning curve!
Another thing: Absolutes do not seat like traditional bullets. You will not measure base to ogive, because these bullets do not engage/touch the rifling like traditionally shaped bullets. Seat bullets at or near the base of the neck and measure the Overall Length. This is your reference. No chasing the lands with these bullets!
Part of the secret to this design is vastly reduced engraving pressure. That's why it takes MUCH faster powders to achieve velocity. Also why these bullets average 200-300 fps faster than normal. Also why these bullets require more neck tension and some add neck crimping. All of this helps hold the bullet while pressure is being developed to speed the bullet down the barrel.
These factors are why Steve recommends only accomplished handloaders should load Absolutes. They are truly a step change in bullet design. As Butterbean says, they are in a league all their own.

I'll probly stick with the 90g Absolute or one in the 90s since I have the 1:10 twist.
