Need help with pressure problems

I had adjusted the factory trigger before I sent the rifle back to Remington. They replaced it with another one just like it .
I'm trying to decide if I'm going to rebarrel it or move it. My wife asked me a while ago if I was ready to quit on it.
I would like to get that forearm off the barrel but I don't want to mess up the stock for the next guy. If it was a shooter I would gouge out the stock without a second thought.
The rifle is not even five months old and we are talking like this. It kills me.

Use a washer as a shim pop three rounds check it.

Or take it to a reputable smith and get him to give it a check

This has to be flat disappointing for you. It is a hard choice to make, when is enough messing around enough. How is your fired brass measuring compared to FL sized now? At least it's opening now without the need for a mallet it sounds like.
I would look at switching out the stock for a Boyd's or comparable, make sure it isn't on the barrel and take the time to bed it also. It won't ever shoot well if it is moving around or the barrel is contacting the stock. Secondarily scrap the stock trigger and put in an aftermarket unit. There are a lot to choose from and it will certainly reduce your group sizes.
Feel free to PM me if you want to discuss any load specifics. Most importantly have fun, that's what this is all about!

You will never know if it will shoot well if the barrel is contacting the stock. Sand or grind out the barrel channel until it does not touch. You need to be able to freely pass the dollar bill between the stock and the barrel.

tr instead of FL the brass I'm just bumping the shoulder back and I'm shooting max loads with no pressure problems. Before I sent the rifle back it was not extracting starting loads.
For peace of mind today I'm going to switch scopes and eliminate that possibility.
I'm going to also try to temporarily fit a couple of small aluminum washers in between the action and stock to get a gap/free float the barrel. If there is improvement I will remove some stock material as to get the dollar bill to slide through. If there is no improvement I'm going to flip a coin to get it rebarreled or hit the highway.

What does fired brass measured at the neck as well as a loaded round at the neck. You may need a little more clearance.

Preliminary report... this afternoon upon returning home from working on food plots I had a short window before dark. I switched out scopes and loaded up for rounds. I scrubbed the bore real good and headed to my range. Fired the fouler and it hit a couple inches right of the bullseye. I fired the next three consecutive. It was dark enough I could not see the holes. I walked down and low and behold You could cover all three with a quarter.
That was with the 123 Scenar and imr 4831 wlr primers.
This is with the stock touching the barrel and the heavy trigger.
So tomorrow it's supposed to rain so I will load up some more ammo , get the barrel cleared and get my scope approved for returning.
That's not a record setting group but it makes me sleep a little better tonight.

Anytime you can cover it with a quarter just slapping a load together that's a good day. Glad you had a glimmer of hope.

I needed that with this rifle.

Today I loaded three rounds with the 129 SST and IMR 4831. I also took the time to work the stock over and got the free float going on.
It shot the three in a horizontal string in a group under 2". The last time I shot this same load it was 3-4".
The trigger needs help which comes next.
I'm starting to think since the rifle is a 1:10 twist It would be best to stock up on some 120 grain bullets.
I also plan to revisit Retumbo powder and H870.

Horizontal stringing is probably due to bedding issue which is what you would expect with the washers. If you free floated the barrel by sanding and bedded it up it should be good to go. Hs precision is not the best stock but they are plenty good enough. I like them a lot.

I meant vertical sorry trying to take care of 3 year old, read and type my bad.

As far as horizontal just keep working on it could be anything and I'm sure someone on here knows way better tricks than I do on what that could be.
