Thank you. This was an informative read.

More 107 data coming?
My rifle is 1:8

Would a 1:8 twist work with the 107s?

My PH3 runs the 107 MK
I hope to see the 107 TMK loaded soon

Excellent report.

Reading the notes it sounds like a lot of meat was destroyed. I get it for some applications, i.e. extremely long range where velocity drops really low. Other than that, I won’t be going the route of soft bullets for hunting. I don’t want explosive terminal performance. I’ve seen the results of Nosler Ballistic Tips and the absolute mess of bloodshot meat. Is a pure match bullet not worse yet? I prefer a well placed hard hunting bullet over hitting an animal with a grenade and wasting a lot of rib and shoulder meat. Your experiences and application may vary.

There are certainly applications for mono and bonded bullets where meat loss is a major factor and engagement distances are closer, ie blacktail deer.

What does NA mean in this instance?

Even past 500 yards at a modest ~2000 fps they’re destroying deer. Eff that. Sounds like a bullet for mangy coyotes with crappy fur rather than something you’d want to eat.

It’s not that bad. I’ve killed deer and sheep with 80 ELD-M’s, 88 ELD-M’s, 77 TMK’s and 112 Match Burners. I’ve lost less meat with those, placing them in the lungs, than a 127 LRX through the shoulder, hitting the femur and shattering it.

No necropsy data recorded.

Thanks @Formidilosus, that's a lot of good info.

I’ve seen a lot of dead deer from a .222 Rem pushing fragile 55gr soft points. Most under 100 yards. Meat damage was minimal. Maybe due to lack of bullet mass? Rarely an exit wound. The after action reports from a lot of these deer sound pretty devastating and given the experience I’ve had with larger mass fast soft bullets they make me cringe. I wasn’t there so maybe it’s not as bad as I imagine. I guess I should try one to get a first hand experience. I get your SMK vs LRX story, but in fairness it’s hard to compare a broadside rib shot to a quartering toward shot that hits a shoulder and rear quarter.
