Have a question about my remington 700 300 wsm

[kcaves]

I'm trying to figure out a problem with my rifle. I shoot 175 grain berger vld. My reloading manual says my overall length should be 2.860 inches. When I measure my overall length. It actually measures out 2.960 up against the lands. The problem I have is I can't get the bolt to close Even at 2.860. I have to make my bullets at 2.260 inches for the bullet to chamber. Even then it causes the tip of the bullet to flatten out. It also gouges the bullet and the brass.

2.860 is the max COL. That does not mean you should load to that COL. I have found that most factory ammo is loaded about .010 shorter then the COL in my loading books. Different bullets will require different COL's too. It is always better to have COL on the short side then to long as being short will not cause dangerously high pressures like it being to long could. Has your brass been FL resized? Has it been fired in this rifle before? Do you have this problem with factory ammo? Im not quite understanding how the tip of the bullet is getting flattened out? Get a sharpie and mark on the bullet and case neck so you can see where its tight when you try to chamber it.

I've never been able to shoot factory ammo as it is too long to chamber. The brass is brand new. I was just using the books COL as baseline. I measured my COL and with the bullet just up against the lands. It measures 2.960, my plan was to go .030 under that. The bullet still won't chamber. That just doesn't seem right to me. My 22-250 and 25-06 will both chamber rounds that are longer than the books COL.

The bullets flattening out doesnt make much sense and is troubling. Did you full length resize the brass and check the length of the brass before you seated the bullets?

 

[WapitiBob]

Chamber a piece of brass to make sure that isn't a problem, then lightly crimp it and stick a bullet in it and chamber again. It'll take 60 seconds and you'll know within a few thou where the ogive hits the rifling. If you're flattening the tip of the bullet you have bigger problems, it sits in space and never touches anything.

This is really troubling to me. If this was my rifle, I'd be calling the factory and/or visiting a good 'smith.

Good advice above. The flattening of the bullet tip is very odd. As said above start with a fully resized and trimmed case, making sure your sizing die is set so it cams over when the case is fully inserted. Bolt the empty case into the chamber to flush out any sizing issues. If the case chambers normally move on to the bullet seating step. I'm to cheap to purchase OAL gauges so I make my own with fully resized brass, you may want to give this a try. When chambering the round, the reliefs cuts in the neck will allow the bullet to be pushed into the case by the lands and give you max COL for YOUR chamber. One of the issues with the Berger's is that with some rifle models the loaded round @ max OAL will not fit in the magazine.

Hope some of this helps you figure out your problem.....

When you're getting the nose of the bullet to flatten, are you putting the round in the magazine before placing in the chamber or hand placing the round into the chamber? I could see the tip issue being caused by the feed ramp forcing the round into the chamber too steeply and causing the bullet nose to ram against the shoulder area of the chamber during the loading process. As others have stated, start with the sized brass first and try to eliminate one variable at a time.

I'm with C.C. on this one. I'd start with a good gunsmith and/ or a call to the factory. If it doesn't chamber factory loads, I'd be worried.

 

[kcaves]

It's probably going to a smith today.

I agree with others something is wrong if factory ammo wont chamber in it. New brass needs to be FL sized before it is loaded. I dont understand how you measured the COL and with the bullet just up against the lands if they wont chamber? Will empty FL sized brass chamber in it?

 

[kcaves]

It will chamber, but the bolt will not close. I too. I to a gunsmith and he says I just have a really short throat on the gun

 

[Colorado Cowboy]

If it was my gun I would contact Remington and relate your situation to them. They will probably do nothing as the chamber is probably within the go-no go specs, just at minimum. I would have a smith open the chamber to give you more to work with.

I have had that problem on a Charles Daly Mauser. The rifle would chamber factory rounds but whenI would FL a fired case it would not chamber. I agree with the thought of eliminating one variable at a time. I took mine to a smith and he said no issues he could see. I then sent the dies and three cases to RCBS and they "shortened" the sizer die just a touch. Now I have no issue but only if I use cases fired in that particular rifle. I had the same issue on a 8mm06. I took the shell holder and ran it across some Emory cloth a few strokes at a time, resized and tested until I got the case to chamber with no issues and that solved the problem. I now know use that shell holder with that set of dies. High maintenance for sure but I found a way to get it done. Frustrating to say the least....Good luck getting it squared away.

If the bolt is not sticking when you try to close it but it won't close, the brass is hitting either on the case mouth or the shoulder. 99/100 times it's the shoulder. That part gets pushed out by pressure and if you don't bump it back, the bolt won't close. Measure the once fired brass shoulder to case head with a case comparator and start bumping back the shoulder. When it chambers you'll be close to where you need to be. Then drop a bullet in and get your ogive to land distance measured. At that point you will be able to chamber and reload and you'll have known measurements you can work from. If your chamber is short enough the sizer won't bump the shoulder back enough you'll need to reduce the shell holder thickness at the top surface as DIYHNTR mentioned above.
If you run the brass shoulder thru a candle flame and "smoke" it, then chamber the offending brass you'll plainly see if it's hitting.

WOW, I have so much to learn. I love these threads.
Good luck with the issue.

Just remember guys, he has trouble with new, unfired factory ammo too................just sayin

Yea I forgot about that. The smith he went to could dust off the back of the lugs if they had some gages. I can't imagine he'd need more than a cpl thou.

 

[Topgun 30-06]

I wouldn't have shot that gun one time if it was bought new and wouldn't chamber a factory round. I'd be taking it back and either let Remington correct the problem or get written communication from them that they will pay for a smith to correct whatever problem there is. I just can't see going through all the procedures you guys are mentioning when the rifle won't even take factory ammo! Whatever is wrong should be taken care of by the manufacturer at their cost IMHO.

 

[kcaves]

Smith said it has just a really small throat and the gouging of the brass is where the throat actually starts. I ordered a new custom made barrel for it and I should be good from there
