Have a Remington long range that had extraction problems. Rebarreled and chambered for 28 Nosler. Third firings on brass would have to strike bolt to get it to slide open. Pressure good, (lift easily just wouldn't break case free). Took it to my gunsmith, found out bolt was out of time and lost most of cam action. Reattached bolt handle within proper spec works great. Just wondered how many others have experienced this.

Sounds like your Smith is on the ball with the fix. This is a very common problem with the latest batch of Remington actions. Amazes me how many smiths true actions on a daily basis but do not address this problem.

Charlie,
Totally agree. I think this is what happens when a huge conglomerate owns a company and is only concerned with the bottom line.

Agreed, but the process of truing the action worsens or even creates the same issue. Most factory Remingtons are marginal at best in this regard. Replacing and properly timing the bolt handle should be a standard part of truing a Remington, IMHO.

I have worked either directly or in support of manufacturing for 45 years. After WWII a US consultant, Juran helped Japan turn around its quality and world wide reputation. He wrote a book Quality Is Free, which upon first impression may seem contradictory. The basis is it costs the same to produce rejects/rework as first quality. There are many similar treatises and it simply boils down to management's expectations, as employees generally do what is expected of them. That said I have only known one accountant who had a clue, and unfortunately they make poor managers outside their area of expertise. It's too easy to turn a cash cow into a piece of dead meat!
I thought it was Deming that saved the Japanese, but I could be mistaken. I learned about building quality first with 20 years at Toyota. Unfortunately the last ten years they have fallen into the ssame bottom line Illness as every other large company. Do your research before buying a rifle or a car!

Hello all, could this be contributing to hard bolt lift on my Remington in 6.5 x 55? Load is 45.5 grains of H4831SC in a Lapua case, 142 Sierra HPBT, BR-2 primer. Velocity somewhere around 2750- 2800 out of a 30 inch Bartlein 5R medium palma. Cases have 8 times through the rifle and have been only neck sized up to the 7th firing and then full length. Chamber is a match chamber, no turn, from PTG. Resized round chambers and extracts easily before firing, after firing hard to extract,no obvious pressure signs but I haven't miked the case head comparing to a new. Don't mean to hijack the thread, but I'm not sure where to go or what else to check. Thanks, Jim
Not a definitive answer to your question, but..as a rule, pressure shows up at the BEGINNING of bolt lift and tight brass or lack of primary extraction shows up at the TOP of the bolt lift part of the stroke.
Think about this..the bolt doesn't begin to move rearward UNTIL it reaches the primary extraction cam. It simply rotates around it's axis until it gets to that point, at which time the cam and bolt handle pull the case free and are supposed to allow for easy extraction.
Some older Remington actions had the same problem. Some don't so much. I learned the hard way that is the first thing to look at before buying a Remington. They are fine actions but suffer from mass production problems that most all American companies have enjoyed from time to time. Having one trued can aggravate the problem.

What part of the action truing causes the bolt timing to go away? Mine was trued and now has no contact on the extraction ramp.
Truing the back of the bolt lugs and truing the lug seats in the action. Everything moves backwards, giving less cam contact.

This is why its not worth fixing a remington up in my opinion. You have the same amount of money in it as a custom action. 250 to true, 50 for a lug, 85 to time bolt, 85 to bush firing pin, 100 for a rail and bed it to the receiver, 570 total plus the cost of the action. Generally guys buy the 700 adl for 400-450 bucks so after truing they have 1000+ into the action. Its way more headache than what its worth. I sell stillers for 910 shipped with a 20 moa rail. Ya I don't make much on them at that price but I can get it in and look it over to make sure everything is good. If it is I chamber the barrel, put a brake on it and bed it in one day. Final assembly the next day and its done. Whereas you spend a whole day monkeying around on the 700 action to bring it up to snuff and its still a factory action. When you go to sell a custom rifle with a factory action prepare to lose your hind end on it regardless of "who" trued it. With the custom action you will get alot more of your original investment back and you have the same amount of money in it. Generally I haven't lost any money on my used rifles I have built as they generally sell within a couple hundred of full retail or at new price. I did the labor obviously so I still made money.
BINGO! This is EXACTLY right, but convincing someone to not use a Remington is often like pulling teeth. I usually tell people, "I'm gonna say this one time, " then explain what you just posted, and end it up with, "I make more money doing it your way". It still doesn't work, about 90% of the time.
But....but....I've got two of the latest models out and the damn things won't do anything but throw the fired brass roughly about 5' and the camming action is good! One is a Tac Model and the other was a DPS I removed from the stock it came in and I dropped the barreled action into an older HS Precision stock I had. So far...I've shot 6 different 5 shot groups with the one I dropped into the HS stock and I could cover all 6 groups with the knuckles of my fist! These were fired from 600 yards. I did change the trigger out on the HS stocked rifle to a Timney and bedded the action.
