Thanks Randy, super helpful photo.I
Fwiw. This was a comparison between the 3 brands 77 tmk.View attachment 584115. It shot fine through my tikka.

I've shot more of them also....its all about the same as that target. However, Black Hills is the king.

Pretty sure it was that 'flier' ...Which shot is your “cold bore”?
The one in the middle.
I'll be starting the cold bore on Sunday, 2 different rifles. Be interesting.

Howdy! First post after reading this entire thread. If it wasn't for a good friend of mine attending a recent shooting school by Form, I would still be mildly choking on some of this info in here.
That said, I dove right in and am the proud owner of a Tikka in .223. Nice rifle. Not the only bolt .223 I have but certainly a favorite after a range session.
The post above about groups and a comment on AAC ammo having a bit more pop got me to post up my experience with that ammo. I bought some AAC 77gn OTM to practice with in the Tikka. I was pretty happy with the groups to start, at 1.25-1.5". I was hitting gongs at 200, 300 and 400 yards easily with this stuff. The potential for very good accuracy in this rifle became pretty clear. I thought that ammo popped pretty good too. I read, "perfectly fine to shoot 5.56 in a bolt gun chambered in .223", here. OK then, lets give it a go, even if I have avoided doing that forever.
I found 3 split cases in 40 rounds fired. I pawed through another 160 unfired rounds, all in the same lot, and found two with damaged case mouths and one with a slightly bulged shoulder. I seem to recall maybe shoving one into the chamber a little harder than normally necessary while shooting at the bench that first day. I'll shoot the balance of it in my 18" Wylde barreled rifle.
Aside from that I do plan to attempt to fill a deer tag here in the hills with the Rokslide Recipe come November. I'll post bullet performance results here.

I ran through @ 400 with a friend's T3x with zero issues. Have about a hundred left and i checked some with a magnifying glass with no visible flaws. Perhaps Black Hills Shooter had a monday morning batch or a newb at the factory? Whatever the reason, the fact that one batch had issues is pretty unacceptable. Whoever is in charge of quality control needs a talking to. That's very bad for business at the least.
don't worry about it, it's helpful.Anyway, sorry for stinking up this thread with bad ammo stories.
Your info is much appreciated!If I recall, you posted some MVs to me that showed they were on the hot side. Average above 2800fps.
Anyway, sorry for stinking up this thread with bad ammo stories. I'll be sure to post something about 77 TMKs and dead game animals later in the year.
