I have some old 300 WM brass from previous barrel. Got my new barrel back from GAP. Tried to FL resize previous brass, but some of them I couldn't close the bolt and the case stuck. Should I discard those? Thanks for your help

Re: Help ! unable to chamber after FL resize.
Brass is cheap, custom rifle aren't. I almost always buy new brass for new rifles, saves a lot of headaches.

Re: Help ! unable to chamber after FL resize.
Hear you Jason. Thought I could reuse some of them. But I am more interested in why it doesn't chamber? Is the chamber has tight tolerance?, or are the brass needed to be retired?

Re: Help ! unable to chamber after FL resize.
What's the story on the old barrel, was it a match chamber or possibly a loose factory one?

the case grows above the belt......here is what you need to re-size to get the cases to chamber...

Re: Help ! unable to chamber after FL resize.
also the case oal might be to long, the brass may need trimming. if the neck is to long you won't be able to lower the bolt handle.

belted magnum cartridges expand just above the belt. I had the same issue
this should fix your problem.

Collet Resizing Die

Belted magnum cartridges have been around for over 50 years, and most shooters that reload them are familiar with the case expansion problems that occur "just above" the belt. This usually happens after just 2 or 3 firings - wasting perfectly good cases. Many shooters have discovered this problem when they find their handloads begin to stick in their chamber, or when they no longer chamber at all.
Unlike non-belted cases, the belt prevents conventional full length dies from traveling far enough down the case. This limits the amount of resizing, and brass is plowed rearward. The brass builds up just above the belt at each reloading, and cases expand. Neck sizing dies don't bump the shoulder back or resize the tapered case wall. The best solution is to full length resize, and use this collet die to reduce case width.
Our unique Belted Magnum Collet Resizing Die solves this problem and has several other great features. The top of this die is a case width gauge that shows when a little "extra" case resizing is required. This resizing die is used to eliminate the case bulge at the expansion ring, after using your full length (or) neck sizing die. Our collet die insures that your belted magnum ammo will always chamber properly and your cases are now able to last for up to 20 firings, even when using hot loads. Our resizing die uses a collet that fits over the cartridge case, until it bottoms against the belt. The case is then pressed into the sizing die. The collet allows your case to go farther into the die where it only reduces the area "just above" the belt.
This ONE die and collet is universal and works on ALL of the popular belted magnum calibers including: .257 Weatherby Magnum, 6.5 Remington Magnum, .264 Winchester Magnum, .270 Weatherby Magnum, 7 x 61 Sharpe & Hart, 7mm Remington Magnum, 7mm Weatherby Magnum, 7mm STW, .300 H&H Magnum, .300 Winchester Magnum, .300 Weatherby Magnum, .308 Norma Magnum, 8mm Remington Magnum, .338 Winchester Magnum, .340 Weatherby Magnum, .350 Remington Magnum, .358 Norma Magnum, .375 H&H Magnum, .416 Remington Magnum, .458 Winchester Magnum, .458 Lott Magnum and several belted wildcat cartridges. There are no extra collets to buy when resizing different calibers. The U.S. Secret Service was one of our first customers to purchase this product.
So far, we've sold over 2,800 of these dies. Unfortunately, the high cost of manufacturing them usually requires us to build a waiting list before each production run. These dies are now in back in stock. So . . . . if you would like to get one, don't wait too long.

Re: Help ! unable to chamber after FL resize.
My bet is that it's sticking at the belt or just above the belt. I've had this issue with another rifle as well. Try the small base die, and it should fix your problem. If not, there's a guy you can send the SB die to and he will "shrink" the die at the base to resize the brass down further. (let me know if you need his info, I'd have to look it up) The easiest and best solution- get new brass.

Re: Help ! unable to chamber after FL resize.
Yes you are correct Chad. It sticks just above the belt. Boltripper has recommended the SB FL sizer. Will give that a try and see. Would hate to throw away 200 - 300 brass that's being fired only 2-3 times.

Re: Help ! unable to chamber after FL resize.
A small base die is a <span style="text-decoration: underline">very bad idea </span>for belted cases, and here's why. The belt keeps any tight fitting die from reaching the web of the case. Small base dies plow the brass back against the belt, where it actually makes your case diameter <span style="text-decoration: underline">larger</span>. That's why belted handloads often fail to chamber after a few reloadings.
That's why I designed the <span style="font-weight: bold">Belted Magnum Collet Resizing Die</span>. It's designed to only push the brass inward. Anyone can easily see what's going on if you measure the case width just above the belt. An ordinary set of calipers will do the job. Just compare the diameter of your cases at different stages of reloading.
Keep in mind that your case width begins at .507" in this area. It's also especially important for reloaders to keep in mind that handloads should NEVER headspace on the belt. Your chamber clearance (at the shoulder) should not exceed -.002" at the most. Even if you only resize the neck you should bump the shoulder back, but no more than .001 or .002" at the most. Failing to get your headspace right is the only thing that will cause headspace separation. To help solve this problem I developed the <span style="font-weight: bold">Digital Headspace Gauge</span>. Very simple to use. You can read about it on my website.

Re: Help ! unable to chamber after FL resize.
Just got a 300 WSM back from GAP had same problem 500 pcs of match prepped brass that would not chamber. I ordered a small base die and resized all the brass I adjusted die so it did not push shoulder back and my over all length did not change so avoided trimming brass. Original brass was fired in FN SPR chamber. Brass is cheap but all the prep work takes time. 300 WSM is not a belted case so YMMV.

Re: Help ! unable to chamber after FL resize.
Tioga .......
Downward pressure is what causes belted cases to bulge, and no die pushes downward harder than a small base (SB) die. I've had a jillion shooters send me their problem cases to examine and diagnose. None of those cases are in worse shape than the ones that have been resized with a tight FL die or a SB die.
Measure your case diameter just above the belt, and you'll see what I mean. The main reason this symptom baffles so many shooters is that it doesn't show up until after the second or third reloading, and most shooters don't measure case width. Other shooters usually just toss their brass long before they should.

Re: Help ! unable to chamber after FL resize.
The Larry Willis setup is the way to go. I had over 50 cases that would not chamber in my new R&D 300win and i tried the Larry Willis die and it worked like a charm.
Great die,good people to do business with.
