I had my sako rebarreled with a bartlin 260rem barrel a few months ago and ever since it was rebarreled, unfired cases have been sticking like I was jamming into the lands. I started out at 2.80coal and I have shortened up to 2.64 coal and it is still doing this. After fired the case ejects fine. Any ideas what might be happening.?

unfired case sticking
Try sending them through the depriming/resizing die even though they are unfired, and make sure you are resizing the full length of the case and not partial. I was having a similar problem, worked in one rifle and not the other in 22-250. Just had to lengthen the die and allow it to resize further down the brass.

Are there any scratches on the brass by the case head? If you have a slight burr from the radius he cut on the end of the chamber you can have the case obuterate into it and make extraction difficult. I heard Dave Manson discuss the condition at a conference and recently came across it in an 300 win mag someone else chambered. It was an awfully small burr.
Editted- I didn't read the OPs post correctly. You have a sizing issues. I thought the fired cases were stuck. Ignore my comments- they don't apply to these conditions

sorry about the the quality of picture. It is from my phone.
This is once fired fl resized brass and bullet seated to 2.765
Notice the marks in the red box. These are the only new marks. They go all the way around the bullet.
if the quality is to bad ill get better pics of it tonight.

Definitely touching the rifling. Use sharpie on the bullet to see the contact better. I´d just modify a case, measure your rifle´s true COL to the ogive and start with the new reloads from there. Remember starting with the bullet jammed into the rifling yields higher pressures, so that also asks for prudence and starting the load development even lower.
i found i have to resize new brass before loading for my rifle. just like i do for once fired brass. seems to fix the problem. the shoulder of the casing is causing the bolt to be tough to close so i run them through the neck and de-priming die.

You went from a SAAMI or slightly longer freebore dimension to a significantly shorter freebore dimension. I suggest you get freebore dimension from the smith who chambered the bbl.
Looking at distance between marks on bullet from lands and case mouth, this would be a great chamber for Berger hybrid or Match BT LR bullets, JLK would also be in the mix.
Those marks could also be throat scrapes like my 204 gives, even .010 off the lands. Shilen cut a very tight throat for me. With that said...also measure the upper body of your brass right where it merges to the shoulder. You could have just a very tight chamber. It sounds like after you fire form, your fine. My upper body measures(204 ruger) .3595", then brass that is .3600" is snug chambering and .3605" the bolt is tight closing. .361 and it wants to get stuck. I have to force the bolt back to pop the brass loose from the chamber. When I size, I watch upper body diameter and shoulder length. This way, i'm fully supported in the chamber without pinching brass into the chamber forcefully.
I have had new brass that wouldn't chamber nice, had to be sized a little like a few guys already said on here.
Also, look on the forum here for articles on bumping shoulders back to chamber sizes.
Usually if I engage the lands hard, the neck tension isn't enough to hold the bullet and the brass ejects hard and the bullet sticks in the lands slightly, cleaning rod pops the bullet loose. If your bullet isnt getting stuck inside, the scrapes could be tight throat and tight chamber is grabbing the upper case body hard. To extreme accuracy shooters, thats a good thing!
