Corrected, thank you
A funny thing about the box has 8.5 recommended, and I was aware of that, but I just felt like this bird wanted to fly. I thing this angel got her wings. Thoughts?

Fierce Edge in 28 Nolser, 26" factory barrel, 1:8.5 twist
118 gn Hammer Hunter Tipped
OAL = 2.834" Base-to-Ogive
Fed 215 primer
ADG brass, previously fired and annealed
No crimp
B/L = bolt lift
E/M = ejector mark
S/M = swipe mark
Clkr = clicker
s. = slight
H = Heavy or Hard
pssr = pressure
crunch = compressed load
Note: In the comments, "s. E/M" = "slight E/M", which means the E/M is visible under a loupe, but not to the naked eye. Thus, my "s. E/M" is most other people's "no mark," and I treat such loads as safe in my rifle under those conditions (temperature, pressure, etc.), although it is on the ragged edge of over-pressure and I use with caution. Same is true for "Clkr" and "S/M". Accordingly, you have to find your own max pressure in your own rifle.

I don't have all the numbers but I have a 174HH load with 65 grains H4350, Nosler brass, WLRM, crimped. 3280fps and .653" 3 round at 100yds. It's out of a Savage 300 WSM Ultralight and the 174s just work even in the restrictive magazine. When I upgrade the stock and go to AICS mags I'll work up a longer round but until then...
6 Remington Ackley Improved, Benchmark 1:7.5 twist carbon fiber wrapped barrel, Lapua brass made from 8x57 Mauser brass, 90gr HHT, COAL 2.995", 50.0gr N160, BR2 primer, 3540fps average on 8 shots, es 18fps. 100yds .3 MOA. Started showing .0003 case head expansion at 51.0gr and pitted primer at 52.0gr. This is with .004 neck tension not crimped. .030 jump

For those who might be considering some kind of 7 mm wildcat I shot my 26" barrel rifle today with 132 grain 7 mm hammer hunter tipped bullets. The case is 338 Remington ultra Mag necked to 7 mm and using 300 Remington ultra Mag brass to gain an extra hundred thousands length in neck. The primers are Winchester large rifle magnum. I used world war 2 h4831 from a pressed paper 15 lb keg.
I fired 87 grains up to 89.5 in half grain increments. Velocity started at 3600, went to 3704. What was so amazing is the group measured 5/8" at 100 yards!

A little disappointed with the speed but still room to go up. May need to try a faster burning powder.

On another note…After shooting a few of the 160 SH’s I worked up previously that perform excellent…N560 is not near as temp stable as I would’ve liked….95F at 3150fps…same load at 37F resulted in 3020fps…

Played with my first HHTs today.
This is my REM model 7, 18” McGowen 1:10 257 Rob improved. I’ll load a few up at 48 and see what they do. These were all in .75”, so guessing I’m done. Gives a good velocity margin for as far as this rifle needs to shoot. No idea where the lands are, but would guess I’m jumping a bunch with OAL restriction in the model 7.
This is my Tikka with 20” preferred 1:9 7-08ai.
Didn’t find pressure with Varget yet, might push a little farther, though this is plenty of speed for this rifle. The Staball seemed to shoot a little tighter, but I was getting pretty cold by the time I shot the Varget load. Have a ton of Varget and very little Staball, so probably won’t pursue that. I know the 118 would be better for this one, but it shoots the 130AH/131HH better than the 119/120 so I started here. Think I’ll shoot the 132 in my 280ai as well, so that keeps inventory simple.
Edit-OAL IS 2.855 which is about 50 off. Thinking about extending the throat on this one a little, since I run a long action bolt stop on it anyway.
