Brass sticking in chamber.

Brass looks like it needs annealed.  How much are you bumping shoulder - .002 ?

[Oh Mah]

most of my brass has come out around .002 under fireform.the rest is between that and .015 short.

Can i anneal the entire brass?

Give it a try and let us know how it turns out.

Annealing is designed to soften the brass where it gets work hardened. Elsewhere, the brass needs to remain hard or you risk catastrophic case failure.

Is bolt lift stiff?

[Oh Mah]

No,transitions very smooth.What Bofire brought up has me thinking.The bolt moves easy chambers easy but it is sprung a little when locking the bolt.I need to check the head space. 

[Oh Mah]

Every time i find a problem i find myself learning.I just talked to a friend of mine i got to the well some are .002 under and some are .015 under and he stopped me,He said where do you keep your case holders?I said in the cabinet,he said well i figured that but how?I said all my case holders are in a cup in the cabinet................He said there's your problem with that.

So i went and checked and between the 4 diff. case holders for the .300 are diff. thicknesses depending on the brand.

Moral of story put your case holder in the die box and store it there when you get the right one for your rifle.  We are machinist and he has ground his to the exact .002 under his rifles head space.Always learning.


                                     Thanks for all replies, without them i would not have come to this.If i was checking with my head space gauge i would have caught the problem before also.

That was my next question. I mark my case holders with a sharpie so no matter what I know which goes where!  Same goes for comparators

Your loading pretty hot, I would back your load down to about 3035-3050fps. That's my guess as to why your starting to get the bulge that develops right above the belt, happens more often after shooting over max loads. At least that was my issue in my 300wm. There is a collet sizing die that will get that bulge out.

[Magnum_Willys]

Yep a few reloads at .015 bumpback will get you to close to head separation way sooner than .002.   Good spotting on the holders - I’ll make sure I label mine.

[Oh Mah]

Just got back from shooting range,Everything checked out just perfectly on the head space and the chamber.Reloaded new brass with imr 4350 instead of the h 1000.Not one sticky brass.FPS stayed close to the h 1000.

I'm pretty sure that it was the brass as stated earlier by a member.I need to start figuring the annealing thing out.    Thanks everyone for the replies.

Not really too expensive IMO and it works great.

You can anneal by hand no problem. If you do it like I do you’ll burn your self before you can over do it
