I’d kinda like to see pics & vids of the “88” in action. Link if possible plz….
So far seems to be about 20+ inches of penetration with a hole almost the diameter of a pop can bored through the rib cage. Bear and moose rib cages pictured. Exit hole in the bear hide was *maybe* 0.3”. Wouldn’t have left much of a blood trail. Entrance holes on the bigger stuff I don’t think a person could find, but on a coyote where you immediately hit bone under the hide there is definitely a blood trail from the entrance.
88’s are not exactly fur friendly as exits less than 10” from the entrance look to be around 6” or so through hide. (Sample of 4 though. 75% had big exits, the other had 20” of penetration and exited with a 1/2” hole).
I may or may not have posted pics and video of the 88 inserted into not-ballistic-gel type stuff at moderate velocities….
Correct.What caliber? Maybe 223ai judging by the case in one of the pics?

Missed the video though.
Not sure of where you are located but based off my environmentals that gets you terminal velocity out to 500 still. I’d call it a winner.First 100 rounds down the pipe of my Tikka. 77gr TMK/24gr Varget/ CCI BR-4 produce .75MOA groups and right around 2670FPS out of the 22” barrel. That in line speed wise with what most of you are seeing? I could definitely go up in charge weight but don’t really see a reason to. Tracks out to 500yards reliably
Considering that my TMKs chrono at 2820 - 2840 fps out of a 20" barrel gas gun, I'd say that is very slow. No worries though, you should still be terminally effective out to 500 yards. However, if I had to choose between .75" groups and 2670fps vs 1 inch groups and 2800fps, I'd go with higher velocity all day. That's more shock to the animal and a quicker kill.First 100 rounds down the pipe of my Tikka. 77gr TMK/24gr Varget/ CCI BR-4 produce .75MOA groups and right around 2670FPS out of the 22” barrel.

My first lot of varget ran 2680 with a 75 eld at 24g my second took 25g to get the same speed this was out of an 18” barrel with wylde chamber. I never had great speed using varget even with the long throat, just couldn’t get enough in the case even seating the bullets way out. Switching to a faster powder will get you some more velocity, and for me better accuracy too. H4895 gave me over 100fps more and the group size was half of what the varget was.First 100 rounds down the pipe of my Tikka. 77gr TMK/24gr Varget/ CCI BR-4 produce .75MOA groups and right around 2670FPS out of the 22” barrel.

Congrats on the bear. Glad you were able to find it. Sux about the no blood trail, though.Another data point for this thread. 140 yds perfectly broadside. 73 gr eld-m. 1 and done. Complete pass through. Lungs destroyed. 75 yd death run. Found it piled up against a tree, looked like it died running. Absolutely no blood trail. Crappy cell phone pics.... sorry!
Update with TBAC CB9 suppressor:I did some load testing today with my new Christensen Arms Ridgeline Scout .223. This rifle has a 1/8 twist 16" barrel. My best load was:

CCI BR4 primers
Mixed brass
2.300" COAL
