I have a mild use rifle that I'm selling , it's had less than 100 rounds through it. It has a custom muzzlebrake and a black ice stock job. The final price will depend on if the scope is wanted or not. I'm looking for a 300 win mag so I can reload it. It will shoot sub- moa with double tap ammo, I will listen to any and all offers. My name is Blake
 
Because when I tried to trim the cases and size them the problem was that the case necks stretch and I can't afford the tool it takes to trim the necks down to fit. I called Hornady and they said that if you don't trim and turn those brass that they won't chamber or fit. So I'm selling the gun, if not then I will keep it and not reload it.
 
Seems that you should be able to hand trim for not much, certainly less that the hit you might have to take if selling your rifle.

Your best bet might be looking for a trade deal with little or no money changing hands. Lots of guys going Short Mag, it would my choice if needing to step up to a .308 caliber mag cartridge.

There is a Classified Forum here on MonsterMuleys. Lots of firearms trade hands there...

I trimmed the cartridges and sized them but they would not chamber in my gun, any ideas. Thanks for the input.
 
Define simple...... If you put them through the sizer should they not be sized when you lower the ram? Unless the necks have stretched then you have a whole different problem , do you not?
 
Getting a 300 win mag won't eliminate the need for a case trimmer. all cases flow forward and need trimmed at some point.

Not trying to be a wise guy here, but it sounds like what you really need is a good reloading manual with some basic instructions and a case trimmer.

I'm a 40 some year long beginner compared to some guys i've reloaded with so can't help you myself but i'm thinking that there are guys here that could write you off a check list of correction upside down and backwards. I do know that when i want to sell a firearm, i usually take it in the shorts a bit to get it sold. Also, the 300WSM is a outstanding big game cartridge if you don't mind a bit of recoil.

Learning about a twist on your dies, one way or another, or something similar, might be a better bet than selling. just sayin.

I have both and ALL cases were trimmed to speck then they were chamfered and deburred and run through a sizer die and they won't fit in my gun. What say you ? I own almost every manual in print and from what I'm told is that this problem is unique to the short mag , because according to Hornady it is. I was told that when you get once fired brass from other people and try to work those brass into a different gun this can be a problem. It's a great gun no doubt, I don't need to reload it that's all. Maybe I will try virgin brass and see if the same problem arises.
 
Are you working with brass fired in your rifle, or a different rifle altogether? sure sounds like a sizing issue, and I bet it can be fixed so you can keep what sounds like a great rifle. mtmuley
 
Yes I bought some once fired brass that was not fired in my gun and that's where the problem started. Brass for this caliber is hard to come by. Is the problem really a sizing issue or something different. I trimmed and sized the brass in small quantities to see what worked and it just didn't work out. How do you re- size incorrectly? Is it the dies possibly? Any advice from you would be much appreciated.
 
Could be a really tight chamber, you may need a custom resizing die made for your chamber, you could take it to a Good gunsmith and let him check it out for you.

You could try resizing then trimming, if you trim then resize the necks may be growing on you some.

I'm pretty sure it can be reloaded for, just may take some work to figure out but if you like the rifle it will be worth figuring out
 
Most factory guns don't have a chamber tight enough to have problems. but it sounds like your gun has one.

This is common in quality custom work none of my customs will accept brass fired from another rifle no matter how I resize it. custom dies will do the trick but just buying new brass and keeping it for that gun is best.


The 300 WSM is not any harder to load for than any other magnum I don't know who told you that.

LAST EDITED ON Feb-21-16 AT 10:08AM (MST)[p]Try turning your sizing die about 1/4 to 1/2 turn deeper into the press. I'd be willing to bet it's not sizing your brass all the way down. This solved my WSM sizing issues when I had one. I sized fired brass from other rifles with no problem.
 
Thanks for the advice I will get new brass and try it. Where do you get custom dies? I will look around for new brass and see what happens.
 
You can order custom dies from almost any die manufacturer, personally I would order Redding, a gunsmith can help you order if you're not familiar with the process
 
Before buying new brass and/or new dies, i'd read waspocrew's post again and try that. I know that when we first started working up a load for my 270WSM, the brass was tight in the chamber and the bolt was hard to close. My Reloading Pard just made slight adjustments, same as he said above, and then the brass was fully resized and fit fine.

Another possibility instead of buying unfired brass is to just buy regular ammo and shoot that to get your cases. You might hunt several years with 2-3 or more boxes of ammo before you need to reload and those cases are then fire formed exactly to your chamber.

Good luck with it!

Thanks for the help , does a gunsmith have to check and measure the chamber, Then is that info used to make the dies?
 
No a gunsmith isn't needed. Custom dies are built off your fired brass and loaded brass. Or reamer specs. But I'm sure you don't need that.

What reloading press and dies do you have? How are you setting up the die? Do you have any new factory brass that you fired in your gun and haven't sized yet?
 
I have a Lee press and Rcbs dies. When I set up the dies I raise the ram until it bottoms out, lower the ram adjust the die in about 1/2 turn in and tighten the lock ring.
 
I have a custom 270 wsm with the same issue. I think you can send your die back to RCBS and they will machine a few thousandths off the bottom to size them further down. I just bought new brass and keep my nosler with my Brown Precision and everything else works in my dads Browning.
 
LAST EDITED ON Feb-21-16 AT 05:41PM (MST)[p]bdog, you don't need custom dies, dont need your dies machined and I bet money you don't have a "tight" chamber. Do what waspocrew said and adjust your sizing die. Otherwise, start over with brass that is used in your rifle only. WSM brass can be had if you look hard enough. Try the sizing advice first. mtmuley
 
mtmuley I agree. RCBS told me if I was to have them machine the die I should be able to resize brass from both guns and it should work in my custom. I didn't do it and bought new brass and never looked back.
 
Thanks to all for the advice I'll try the new brass and see what happens. I may even send my dies back to Rcbs and cover my bases.
 
I agree with the others, try the sizing suggestions first, try trimmng after sizing, try new brass, process of elimination, if none of that works then go down the custom die path, I was just offering up that as a possible solution.

Let us know how it turns out, I'm sure something suggested on this thread will work!

My buddy has a lee press and we have to set it up to cam over pretty good. Do as suggested and turn the die down another 1/2 turn. If that doesn't work then the die may need to be machined a bit off the bottom.
 
While not impossible the chance of an RCBS die being bad is very slim. I'd make this my last consideration.

His description of how he's setting the die is correct.
he says he's trimming to length. if this is all right then it comes back to a chamber smaller than the die. uncommon on a factory rifle but not impossible. and he's never know the difference if he hadn't bought brass fired in another rifle.

I tried it last night and brass fired in my gun will not chamber, so I went back and sized it again and it still won't chamber. I tried brass that were under trim to length at this point I'm all but convinced that the die is bad. To be clear the brass was under 2.09 that the manual says is the trim length. I'm gonna order a Lee die set and see if that fixes the problem. I've adjusted the die inward 1 full turn after it was bottomed out on the ram.
 
I had a problem similar to yours reloading for a buddy's 270 wsm. The problem was we wasn't bumping the shoulder back far enough. I took a marker and colored the shoulder and tried to chamber it. It should show rub marks if they need to be bumped back more.
 
I just adjusted the die down a 1/4 turn at a time until the cases chamber. Then I left the dies set up for that gun only.
 
I've adjusted the die all the way in and every where in between and I'm not getting the results that others are getting . It's still not sizing the way it's supposed to.
 
I'm not getting the cam over because I have a Lee press and so it's not sizing or setting the shoulder back like it would with a rcbs press.
 
Has the brass that you're using been shot in YOUR rifle?

Here's a couple tests:

Full length size your brass using the supplied directions and THEN try one in your rifle. If it fits fine then the issue is with bullet seating. If it doesn't fit go back to square one.

The seater die has an internal ridge for crimping which will contact the case mouth and create a bump or bulge in the neck and make chambering impossible. In other words: you're screwing your seater die body too deeply. Bullet depth should be controlled by the little seater screw plug NOT THE DIE BODY. Only run the die body in, by hand, until it contacts the case mouth and then back it out 1/4 turn or so.

Keep at it,

It's a Weatherby Vanguard S1 , are you interested in the scope or no? The scope is a vortex viper in the 6.5-20x50.
 
Have a Tikka T-3 in 300 WSM. I had the same issue when I got my RCBS dies, using them in an old RCBS press.
(I never trim / chamfer until my re-sizing work is over.)
To get once fired brass from my rifle to chamber I had to turn the size die all the way in until it touched the shell holder and them turn it in until the handle on the press "bumped" over when sizing a case. Then and only then would the re-sized brass chamber in my rifle easily.
By the way I use brass W-W cases not nickel plated cases.
This cartridge is probably the finickiest of any I load for in regards to case sizing, at least so far.
 
If the brass was fired in your rifle it should fit regardless of how you set the die.

maybe your die is junk after all.

Maybe I shouldn't read literally into what you typed but, in one of your posts you said you trimmed, chamfered and then resized...

Resize, then trim, then chamfer in that order because cases can and do change size when run through a press. if you trim then resize they'll change.

Hope this works out for ya...

Take your expander and decapper out of the die. Put a case in the shellholder, then slide a feeler Guage underneath between the shellholder and the case. You can get 2 to 8 thousandths more bump on the shoulder trying this, before doing anything else and it will give you a good idea what the problem is. Ce61
 
This thread is the classic example of the guy asking "where can a guy get the best fish dinner" and we insist on telling him where to get steak! LMAO

I'm to blame as much as anyone since I want to help solve his very solvable problem.

I think the OP should have simply said he wanted to sell a rifle. Especially if he's not going to take the advise given here.

Hey, the guy wants to sell a 300WSM and buy a 300 Win! That's up to him, I suppose.

Zeke
 
I am here to report that rcbs dies do not work on a Lee press . I bought a Lee die and my brass now fits in my rifle. If the right deal comes along for my wsm I will listen to it and make a decision at that time. Thanks to the community for all the advice on how to solve this problem that I have battled now for over a year. Thanks a lot !!!!
