I have about three shots on this Nosler brass and now its starting to stick on the very last bit of the stroke on the handle, I havent changed anything, when the brass was new it extracted just fine, but now its stickin with the same exact load, not sure what the problem is, I am FL sizing Nosler brass, and its a remington sendero, and like alot of rem. it has an oversized firing pin hole. thanks

I trim it after every shot its not too long its only stickin after I shoot it.

Brass is cleaned and tumbled after every shot.

Bright shiny brass on the back end of the case, where the extractor hole is on the bolt face- as in the brass flowing back into the hole slightly?
 
Yes, there is slight marks, but hasnt been there on the last 3-4 shots. I just talked to a guy that has been shooting a 300 RUM along time and he said that he tosses his nosler brass after about 4 shots. Sounds like I am getting case head seperation. I am running a 185gr berger vld with 96gr of h1000 and its right at 3350 through the crony. Anything else shoots like crap, this is where the gun likes it, I have tried other powders like Retumbo and etc. and it likes 96gr of h1000 and shoots about .5 at 100
 
Then the load is to hot for your gun. Short brass life is a shure sign of too much pressure. Sticky bolt is too. Now wipe marks. Back down or risk wrecking yourself and the rifle. Unless you like running on the edge, some do!
 
Try annealing your brass 1st before you toss it. But you should be getting more than 4 firings before that happens, 2nd what ninehorses said you should probably back off a grain or so on your charge.

His problem is at the back of the case - not the mouth. Annealing will do nothing for this problem.
 
Back your charge down and work your seating depth. You can get the accuracy back. Or try a different bullet. I know some are set on a bullet but if you have to run balls to the wall to get it to shoot good then I'd look at a different pill

Why does it sound like you are getting head separations??

What do you think cat shooter. Am I getting casehead separation, why does it only do it after the brass has been fired 3 or so times

Why else would the bolt be sticky only after the 3 or 4th firing, something is happening to the brass, I dont know thats why I am asking
 
First I would quit FL sizing by backing out the die one turn. Next, I would back down and change brands of primer. You are using magnum primers, I hope.

If you only have one 300RUM you don't need to FL resize, as these rounds will only be used in your rifle. If they came out, they should go back in. If they won't, give the sholder a ever so slight bump, like a 1/32 or 1/16 turn of the die untill they will chamber.

You mentioned case head seperation, are you getting a bright ring 1/4" forward of the rim? How about loose primer pockets?

If you are getting ejector wipes, then the pressure is WAY too high.

Nosler brass has a reputation for being soft.

Excessive presure will cause the case head to expand until it is puching brass into the ejector hole.

If your groups get lousy with lower velocity, then "Tough titties"

You gotta switch bullets until you find a load that your rifle can live with.

You won't blow anything up, but you will push brass into places it doesn't belong.

The primer pockets are soso after three shots, the REM. brass wont even hardly hold a primer after 2 shots, I already tried nosler bullets, I think I can live with 3-4 shots, It shoots good so o'well I guess its the price I can pay for owning a hotrod.

Dont think its that bad, I am not even at the books max. My gunsmith told me with out anealing the cases then I probably wont get more than 3-4 shots out of a 300 RUM unless I load it down, well I didnt buy a 300 RUM to shoot at 300win mag velocity's. Its like buying a swift or 22-250 and loading it down to shoot like a 223, what the point. I have already put almost 200rds of this same load down the tube so whats gonna Happen.

Second I do not reload for speed, I reload just for acuracy, and that is where the gun shoots best.
