If anyone is looking at hammer bullets, the absolute hammers are very interesting, in that they can potentially get really fast for weight.

Finally got to do some shooting over the weekend with some AH's. I started pretty low and have room to continue working up, which I will do in the next couple of months.

These were measured through a magnetospeed at 700' above sea level and ~45 degrees.

6.5 creedmoor
tikka t3x, 1:8", 24".

lapua brass, cci-450s and 123gr AH
IMR-4166, the new enduron line to approximate varget's burn rate; approx 15thou jump

36.0gr --2654 fps
37.0gr --2757 fps
38.0gr --2808 fps
39.0gr --2864 fps
40.0gr --2955 fps
41.0gr --3032 fps

I shot 42.0gr, but the magnetospeed had moved a bit on my barrel and i didn't notice, it did not record, but i'm guessing right at 3,100. No pressure signs anywhere. I will load 41.5 and go up in 1/2gr increments for a few more grains to see what I can do.

the POI for 37-39gr were about moa at 100y and very close to poi of my 130gr berger hunting loads, so i took one of the 39.0gr loads and shot a small doe at 205 yards that evening. entrance was forward in the shoulder, exit in the center of the shoulder mass. results were devastating and the deer didnt' so much as take a step.

280AI
Kimber hunter, 24", 1:9" barrel.
I tested 2 different powders for this one.
Nosler brass, cci-200, 140gr AH loaded to mag length.

IMR-4166
41gr--2494 fps
42gr--2552 fps
43gr--2625 fps
44gr--2677 fps
45gr--2717 fps

With no data on the 280 with the 4166, i started very low and have a lot of room to work up. if these incremental values hold up with regard to velocity, i believe 53+gr is attainable. I will probably continue to work up in 1gr increments until i get to 51, then start 1/2 gr increments.

H4350
53--2792 fps
54--2847 fps
55--2893 fps
56--2978 fps
57--3007 fps
58--3069 fps
59--3132 fps

no pressure signs whatsoever, the last piece of brass/primer looked just like the first. I will continue up in 1/2 gr increments to see where I find pressure and see how hot I can push these.
