Comparing apples to oranges.
The 101 HH is a solid copper bullet.
I actually bought some 88gr for my 6CM, and Steve had previously donated the 101gr to test in the first ever built 6SST I did load development on. I had some left over, and the 101s actually shoot better in my 1:7.5" than the 88s do. So I bought some more, and run them in a unit that requests non-lead projectiles.

Running the 108's in a 22" 6 creed at 3050. Have shot a whitetail buck at 456 and a cow elk at 500. Terminal performance was stellar on both shots. Neither animal went more than 10 feet. The cow elk was quartering to me and I hit her in the front shoulder. Busted the front shoulder and destroyed the vitals. I'm definitely impressed with these bullets. Will have a chance to shoot them on a couple more cow elk (kids) this year and will be using them on a Coues hunt in Mexico next month

Thank you Sir. Appreciate the info

not trying to cause a fruit fight here...certainly not trying to compare any bullets here. Especially ones I have no experience with. However, I do have quite a bit of experience with monolithic bullets out of Several calibers. I've LabRadar chrono'd hundreds of different combinations of several bullet brand, type and composition.
Generally speaking, comparing same/similar BC with similar style (Boat tail, ogives, FF, etc; regardless of composition; they will travel a similar path. So with all do respect sir. just because it's a copper pill; isn't really making my statement a lemon. (Couldn't resist the punny).
I'm excited that those 101 monolithic pill shot better in that faster twist. Wish I could find them here.
Although I'd suspect the lower limit on that twist is similar as an 8tw. ~58gr as would the upper limit. For most G7 pills in the same class your only looking at ~3% different in SG At lower weights. FWIW if it hasn't been noted yet. The 108 EH has a Miller SG of 1.49 (1.5 is minimum standard SG) @3100 FPS In a 8 twist. the Berger 115gr VLD is SG marginal @ 1.48 EVEN with a 7.5 twist @3100 FPS. It's on at the upper weight limits that higher SG degradation happens. And this is very difficult to overcome if not impossible no matter the extra speed. Hence the minimum 7 twist.....nothing new here. Same Dilemma with the 270 win with 170 gr However the 27 nosler will solve that with their 9.5 or 9 twist. I suppose sig sauer could if it wanted to with the Fury.
just my 2c. Sorry for the rambling.

All good and pertinent info.
I am just saying the bullets are nothing alike.
The BC on all the Hammer bullets I shoot/have shot seem to be inflated. I have tested each from 100 to 921 yards, and have found actual drops do not align with what listed BCs should support. 6mm 88gr, 6mm 101gr, .257 121gr, 6.5mm 124gr, 6.5mm 131gr, 7mm 143gr, 7mm 155gr, 7mm 177gr, and I have some .308 199gr and 6.5mm 129gr AHs coming today.
They definitely have their place for hunting, but they are in a totally different class. They do work very well for higher impact velocities and short/medium hunting ranges. "Medium" being totally user specific. For me, that means out to 500-700.
I have found every one to be very accurate though. Sub-half MOA has been very easy to find, usually less than 20 rounds during load development for a repeatably accurate load.
I, too, have shot 10s of thousands of rounds testing/loading various bullets and rifles. On average for the last 6 years, about 4800 per year. About 1/3 of those are between 545 and 1200+ yards.

Wow. From what I remember when researching hammer bullets, they touted that they don't inflate their data.
Berger stability chart shows 1.73 for the 108 EH @ 3100 fps with 8 twist and 4000 ft elevation. Have shot enough 6 mm 105 and 108 target bullets at 1000 yards on paper that I would think 8 twist be perfect for this bullet for best accuracy.

Im shooting the 109 hybrid in my 6slr with a 26" tube. 3210 fps mv. Bc is definitely better that advertised. Impacts are high from 200 all the way out to 1100. Shoots one tiny hole and was easy to get to group well. Have killed a few coyotes and a bunch if prairie dogs so far. Performed great on all of them.

42.4 grains H4350, Lapua Brass, CCI 450. I will play around w RL26 soon but just through this load together to get the bbl broke in.
Have fiddled with the RL26 in both the 6 and 6.5 and it is crazy fast. I haven't done a proper temperature test, but over about 80* it gets funky. The CCI450's will ignite it just fine below zero. Any other primer is questionable at best. Thanks.
