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.

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?

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.

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 .

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 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.

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:

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.....

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.........

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
