I am using lee resizing dies and I have trouble with the handloaded cartridge going all the way into the chamber. The brass gets a full length resize but the Browning Bar semi auto won't seat the cartridge all the way in. The bolt remains about 1/16 of an inch open. I checked and the bullet is clear of the lands. I cleaned the gun, but the problem still exists. Any suggestions as to what might be the problem?
 
Is your sizer die a full length die? Is the shell holder just kissing the bottom of the die when the ram is all the way up? Check the length of the brass too. Trim, chamfer and deburr as required.
 
You probably need a set of small-based dies. These will constrict the brass a bit more in the base section and make the cartridge easier to chamber in your auto-loader.
 
Your brass is not full length resized. Did your shell holder bottom out on the die? Get yourself a Redding body die. You can run your loaded rounds through them and it will resize the body and bump the shoulder back to spec.
 
I am thinking your cases might be over length.Semi autos and levers are more sensitive than bolts.Have you trimmed to length?
 
still puzzled

Sunray, Boo, Maynard, Jim and John. Just a brief history of the reloading. I polish the brass, decap and resize, trim to length, Chamfer and debur, reprime, add powder and seat bullet.
The decapper and full length sizer touch the shell plate, firmly. Prime, charge, bullet seat and then use factory crimp die. I wonder if I am swelling the case with the factory crimp die. All this just started to act up in the last 100 of 200 and some rounds. The first 100 work ok then I had to change everthing and set it up again for the last 100(new molly coated bullets). If it does closed on the round I can't get the action open without a tree handy.. I hope its not bullet pulling time.
 
I would go with Maynard sugestion Get a Redding body die and run the loaded round though the die.

This should bring the brass back to Factory spec.
 
What type of press are you using? I had this problem once with a rem 7400 in .243. It turned out that I wasn't pushing the handle down hard enough on my Lee classic press. Make sure there is no light visible between your shell holder and the bottom of your FL die.

On the other hand if your using a press with an overcentre mechanism, such as a Rockchucker, the Lee factory crimp die is not made for use in these presses. You may be pushing your round too far into the crimp die and flaring/bulging your brass.

Good luck.
 
resolution

I am trying to find a Redding body die because I covered the cartridge with machinist layout dye and shoved it in the chamber. It came out with dye scraped off of the case about 1/2 - 3/4 of an inch up from the head stamp. If I can find a body die in Alberta I hope it solves this dilemma. Thanks to all who contributed.
 
Bullet pulling time

I checked into getting a Redding full body die and to order one from the states was $21 +shipping +brokerage +taxes = to much. To get one from a local shop was $55. I just finished pulling all 100 projectiles out of the brass. All this grief was cause from there being a little space between the die and shell plate. I’ll know better next time! Thanks and happy shooting.
 
So how long did it take you to pull 100 bullets, resize and reload? Sounds like your time is worth about $3/hour:p
If you order from Sinclair tell them to send it regular USPS. Don't ever have them send it by UPS, unless you like being raped.
Now phone Sinclairs and have them send you a body die for every caliber you load for, it will sure save a lot of time and :bangHead:
 
I find that Japanese and European guns have tighter chambers than USA guns.

If your crimp is not causing the problem, I would suspect you need a small base sizing die.

Can you see any marks on the case to suggest where it is binding? Try painting the case with a full length stripe from a felt marker. It migh show you where it is binding. if it is near the case base, you need the small base die.
 
Any suggestions as to what might be the problem?
Has this brass been fired in another rifle? I've had this problem several times with range-pick-up brass. Even after FLR with small base dies, I still had a problem in one particular rifle.

Try new brass and fire it only in your Browning after FLR and I'll bet the problem is solved.

The solution after checking everything out, was that I had a very small space between the die and the shell plate. That last 20 thousandth of an inch means allot to a semi auto. After fixing that, everything runs smooth.
