All cases were full length resized, trimmed, tumbled, and loaded together. the powder charge was a mild load. I loaded fifty rounds. Some cases chambered very easily, others I had to strongly force the bolt closed. most extracted easily, but on some i had to force the bolt open by beating it open with the palm of my hand.
When closing the bolt, on some cases, it felt hard and "gritty" thats the only way i can describe it. I have been reloading for over thirty years and have never had this problem before, the only thing i did differently with these cases is, i added some flitz tumbling polish to the media. The cases were tumbled prior to resizing, and after resizing to eliminate any lube on the cases.
No cases showed any signs of pressure. Could the flitz have caused the problem? I wiped down the cases that had problems, and no lube came off. they were perfectly clean. Any advice concerning this problem would be greatly appreciated.
The rifle is a Remingtom 700 BDL in 300 RSAUM.

Although your notes indicate you were very careful it appears to be pressure related to me. Could there have been some of the tumbling media that was still in the cases?

the good thing is it not a presure problem from what you saw. I would guess that the stuff your polishing with is getting into the case mouth and that is making hard to chamber.If the gun didn't do it before you used the stuff chances are it's the cause.
I had my rem 700 in 22-250 get a case stuck after firing it shot 1000s of round same load never a problem but was up in the mountains about 6000 ft had a crow flying right over my head staight up got tired of it giving my spot away so i took a shoot at it dumb thing to do i know.But when you point the gun straight up the powder is laying differently in the caseall at one end over the primer .Had to get a pipe to open the bolt blew the primer expanded the primer pocket what a mess.Good reason not to shoot in the air.

Maybe..... If the flits lft some residue on the bullets before sending through the sizing die, it caused the cases to slightly "catch"here and there causing some deforming . I certainly dont KNOW, but seein as thats the only change you made. The grit feel does not really fit this thought though. If you've got any left you did not shoot, perhaps you can go to town with your callipers and find some irregularities. Good luck.

is this the first time reloading for this gun, if it is your barrel could be on out of whack, when i had my 308 norma mag built my first three shots out of it i had to beat the bolt open,the rounds chambered nice but would't extract, i took the rounds to another gunsmith that i new and he looked at the cases and found out the chamber had been reamed crooked i had to replace my barrel,whats worse he told me excactly who had built my gun and said he did extremely good work or extremely bad work and nothing in between,so i would check my cases compare the fired ones to one that is full length sized and see if there is any noticeable difference,if this is not the case and your brass,primers show no signs of excessive preasure it has to be something else,hope this helps

I have a lot of experience with this sort of problem. Maybe not this exact problem but similar anyway. I have found that if it chambers easily then it will probably extract easily, but not in all cases.
Conversley, if it is difficult to chamber some will come out easier than they went in and some will be almost impossible to get out.
This sounds like a sizing issue to me. If you cannot see or feel any residue on the outside of the case it is unlikely that the Flitz treatment is the cause.
Use your caliper as previously advised and see if there are dimensional difference of a magnitude that would cause this problem.
Remingtons use that little metal chip for an extractor and you are lucky it didn't just pull through your case rim. I have had that happen more times than I care to admit.
Good luck.

There are many possibilities that can cause this. Make sure your cases are clean of any lube, check the size of the case after sizing, make sure your chamber is clear of any gunk, Sometimes this is caused by a build up from the prior shell that was fied, other times if may be some crude from lubing the case, it maybe some tumbling medium and there are many other reasons I can't give you a real answer without see the rifle and the cartridges.
Good Luck,
Jerry

Were all the emptys frired in your rifle? If not I would say that the cases were over size and not full length sized.
As for the "grity" feel, If a case chamber easly then it turns with the bolt. I the case sticks on chambering then the bolt turns on th case and feel grity.
I would find a case the is hard to chamber and measure it at the shoulder and above the rim. I suspect you will find one is oversized.

Varmintcaller, Are you crimping cases at all? This sounds to me like a problem I had just this week. I had a bunch of cases in various stages of prep on my bench sorted by headstamp. Somehow I grabbed a dozen or so LC that had not yet been trimmed. They got primed and as I was loading and seating (With my die backed off just short of crimping) I felt a couple of cases get "tight" toward the top of the stroke. These cases were too long and were crimping just a tiny bit as the bullet was still being seated. This in turn was just barely collapsing the shoulder and making a ring right at the case wall shoulder junction. As I attempted to use these, the bolt would hang up just slightly on the down stroke, maybe not gritty but definitely heavy. Mine however seemed to extract easily but were fireformed right back to normal. RD

I took the rifle to the range late this afternoon with some cartridges i had loaded about six months ago. These shells had previously fired in this gun with no problems, same powder same bullets and primers. and had not been exposed to the Flitz.
Same problem, had to beat the bolt open on opening and closeing on some of the shells. There was a nice man there at the range who said he was a retired gunsmith. He checked my bolt and said that only one lug was making contact because it was only showing wear marks on one side, the other lug was still black.
He thought my problem was in the action, and advised me not to shoot the rifle again untill i could have it checked thoroughly by a gunsmith he recommended, he checked my fired brass and agreed there were no signs of pressure. Im going to take his advice and have the rifle checked, and ill have the chamber polished, if that doesnt do it im going to scrap the rifle.
When i first bought this rifle it shot beautiful groups, then it went fom under an inch at 100 yards to 1 3/4 inches, then to about 2 1/2 half inches. I had the action glass bedded, and the barrel free floated (eliminated the pressure pad at the forearm tip) this was with the synthetic stock that came with the rifle. no change. I then ordered another stock made from walnut, a Remington factory stock for short magnums. No change. Now I have the bolt problem, Im pretty much fed up with this rifle. I think i just got a lemon.

Why not have the bolt problem fixed and then sell it a gun show? Sometimes we have a mix of man and machine that just doesn't work well. This sould be like the car that nickle and dimes you and the next guy gets a car with no problems, then you wonder if you should have kept the car. I say get rid of it, before you start wondering if that rifle has a curse on it or worse the rifle has put a curse on you.
Just my 2 cents worth,
Jerry

Thanks for the good advice Jerry, I was told to get rid of it at a gun show, but i couldnt do that to another sportsman. If polishing the chamber and trying to fix the bolt problem doesnt work, I think im going to have the barrel pulled and maybe sell the action to a wildcatter. If there is anything wrong with the action Ill just scrap it.
I want to thank everyone for their replies and suggestions, youre a great group of guys.

Since the retired gunny said there was only one lug engaging, I would have the rifle checked for 'lug setback'. This problem is said to crop up in certain surplus Mausers where the heat treating was not done properly. Could be a new bolt may fix the problem. Good time to have a good gunny lap the rails and do a few 'accurizing' tricks to it too. Maybe turn that lemon into some nice lemonade......

This morning while shopping with my better half, I decided to stop at the local gun shop, I got into a conversation with the manager about the problems i was having with my Remington 700, 300 RSAUM with the J lock bolt.
I told him that i was about ready to wrap it around a tree and get me a Howa 1500 in 300 Win Mag. He said that he didnt have one in the store but checked his inventory list, and said that he had one at one of the other stores. It comes with a Nikko 4-10X scope for $425.00 out the door.
My wife asked if that was the same caliber as the Remington, and I told her basically it was. She said well, I think you should buy this one and quit messing around with the other one. Thats the reason we have been married for 47 years...SHES A KEEPER!!
BY the way, the manager said i should be able to pick up my new rifle in about a week, He will give me a call.
In my previous posts i neglected to mention that the rifle had the J lock bolt, when i mentioned this to the manager of the gun shop he said ...no wonder your having troubles, those rifles are crap. and he is a Remington man, said that he wouldnt have anything but a Remington.and never had any problems with them.

I had something similar with a 243 Rem 788. I took some 308 brass and resized it for 243 w/o turning the neck down it fired ok but I had to use a block of would to get the bolt open.
