.223 AI PN #2 contour on a 700 action in a McM Classic bedded by me (which I'm thinking is the issue as I've looked at everything else).
The three groups were shot last night at 200 yards, load is-
Formed Lapua case CCI BR-4 27.0 RL-15 Sierra 65 SBT kissing the lands
I get the same two in one out with 75 AMAX as well.
Scope has been swapped, screws are tight, good trigger, bench technique is solid, went so far as to shoot it with the mag assembly removed to check for binding, 45 inch pounds on the action screws, front sight base screw not bottoming out. I'm at a loss on this one........
What is your twist. Regardless, in your case I would say the problem is Pacnor, haha.

have you tried different scopes and different powder?
I pulled my scope, cleaned gun, and buried it deep into the safe. I'm over it.

My dad has a Hi-Wall in 225 Winchester that did that exact thing. I went through over 150 bullets of different types, different powder, primers. scopes and nothing seemed to help.
I sent the barrel back to Douglas, they kept it and sent a new contoured blank, it now shoot nice round 3/4" groups.
Sure not saying that is it but maybe?

Is there bedding under the shank? I fought my 6x45 for a bit. After nipping the start at the fn start list, I bedded it with a float all the way to the lug and tip pressure and it finally tightened up. MR contour.
Don't know if it was just my lucky day or not, but no more bedding under shank for my stuff.

Dogcatcher-
Different scopes, bullets and powder have all been tried. I'm over this siht too, wont bury it though, just rebarrel and try and start fresh.
16 Bore-
Yes there is bedding under the shank, this barrel has a 1" shank, bedded the full length of it. Next stop is the Dremel and a re do of the bedding .

I feel your pain. Easy to see why so many damn Tikkas get bought. Seems Chad Dixon is a fan of bedding only the lug and no shank. FWIW.
Bedding always seems to get monkeyed, yet I've never seen a tutorial/thread worth a schit to read about it. Trial and error...and Dremel. .

I would offer this observation for your consideration. I have alot of custom rifles as well as factory rifles and have been in your situation before. Check to see if the bolt handle is touching the stock. Secondly and most important, the crown may not be as perfect as it looks. we use a Manson crowning tool with expandable mandrels or pilots and find that even rifles that cost $3000 to $4000 dollars were improved by recrowning with an 11 degree crown. Alot of barrels sre drilled off center and are not exactly round . It can be done in 10 minutes on the gun. The gun smiths around here are using them to get a concentric crown. We have never seen a lack of improvement.
SHOOT STRAIGHT AND OFTEN. Hunt with your kids. Teach them not to shoot anything that they are not going to eat. Have respect for all ANIMALS.

Funny you mention Tikka, one of the most accurate rifles I own is an old 595 in .243, the thing is so accurate its ridiculous. Bought it some years back as a beater, I've wrestled with the idea of dropping it into a McM and making something out of it, 1/10 twist rate and mag confines always puts an end to those thoughts though. If I could find one of the older T3's with the 8 twist in .223 I have a feeling a lot of the more expensive rifles I own would find there way to the back of the safe......

We have never seen a lack of improvement. That reminds me. Check that the front action screw isn't hitting bolt head. Sharpie it up and open/close the bolt a few times. Base screws while you're at it. Ask me how I know.....

I have a McMillan for a Tikka sitting in my safe right now. I'm done with the custom gun game of roulette. I'm thinking a 7 mag would fit the stock nicely. My current Tikka's 3-shot group at 600 yards: My $3000 custom's group at 100 yards:

$268.00 Ruger American is starting to look tempting as a stopgap while I fiddle with the 3 customs and a Montana that are frustrating me currently, damn near disposable at that price with no custom rifle wait time..........
Wont swear off building just yet, but I think I'm done with Montanas, I'm 1 for 3 there and at $1200.00 I think I can do better, blasphemy I know.....

75 HPBT at 200 yards 65 Gameking showed great promise the other day, need to see if it can repeat it now. Not ready to quit on this one yet, had another .223 that got tripped though, every trick ever suggested has been done to both. Have a straight out of the box .308 that is sub MOA with a half dozen loads. Just getting tired of laying down $1200 to play roulette with a rifle. They all need a little tweaking the Kimbers seem to have become a full time job for me, they're not fun anymore, I want to shoot not tweak.........

I feel your pain. I've got a 270WSM in the safe that I haven't even touched yet. Been fighting another rig as of late, and not in the mood to start another.

2"orange circle or a 2.9" vertical group at 200 yards. Haven't given up on this one yet though, 5 shot group at 100 with 65 Gameking, gonna see how it does at 200. Maybe take the bedding out from under the shank or full length bed if that doesn't work

Lack of shooter skill. Pretty obvious since you are the nut behind the butt...
I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole. BSA MAGA
