What is the cases over all length, has brass stretched and neck is hitting the chamber throat? I haven’t seen you mention measuring the brass length or trimming
I shoot starline brass in my 6.5cm. I've shot that bullet a good bit too. A bullet should slide right into a fired case. How new is this gun?I looked up what a donut was, and tbh i don't think that's it as the bullet wont even go in the the top of the brass. Only the boat tail sits there.
Which means I might have super tight brass. I measured the ID and its still at 0.260 on a fired case
Starline doesn't grown hardly at all in mine.Could be, but that’s pretty hard to end up with brass that long after 2 firings.
Let me clarify some terms:Yeah i've measured it consistently with 2 different calipers.
Brass is between 1.909 and 1.911
COAL has been 2.803 Max
TBH none of my bullets fall into fired cases (including 308s and 300 WM with appropriate bullets). The 308 at least go past the boat tail
Fired bras .296
Loaded Brass .290
New Brass .289
He said he’s only got 100 rounds on the rifle. +1 on Starline being tough.I shoot starline brass in my 6.5cm. I've shot that bullet a good bit too. A bullet should slide right into a fired case. How new is this gun?
I was referring to case length, not cartridge.He said the OAL was spot on on a pulled down round, and the rifle only has 100 rounds down the tube. So unless he started with used brass…
@DocRDSI was referring to case length, not cartridge.
He just posted measurements btw
I shoot starline brass in my 6.5cm. I've shot that bullet a good bit too. A bullet should slide right into a fired case.
Let me clarify some terms:
By fall, I mean with gentle finger pressure does it slide freely. You may have to wiggle it gently to get the projectile started straight.
By fired, I mean fired and not resized.
.2969 is SAAMI standard. Loaded ammo of .290 (seems a bit small) should release fine, and once fired a projectile should slide easily inside that neck.
Well, I'm not really following that... You mean if the chamber is that tight at the neck?Not always especially when you only have .006” clearance in the neck.
So you have a chamber set for a particular brass then?Again, no. Mine don’t. If you have a chamber with machine gun clearance then yes.
Yeah, those would be some of the specific tools I mentioned.Pin gauges.

Almost as good as the time I screwed my SilencerCo Chimera-300 wrong on my 300 Win Mag ... and had to call a cease-fire while I walked 15 yards downrange to pull my destroyed suppressor out of the sand. Those are the lessons we learn ... FOREVER. Thanks for sharing.
allright before this turns into a shit show (too late!) I popped off my barrel and did a "plunk" test.
Known Good ammo from last week protruded .260 from the chamber after a "plunk" drop (repeatable)
SHitty Bad Ammo from this week protrudes .325 from the chamber after a "plunk" drop (repeatable)
Clearly this ammo did not get sized properly. (Which I knew because I used the wrong comparator which told me a false reading, that then gave me fits, yada yada yada: TLDR Badly Sized Ammo.)
It doesn't feed well in either Creed I have so its clearly suspect. Before we rape each other further:
I fucked up.
I didn't catch it right away.
I shoulda stopped when I had feeding problems and just torn everything down.
Let's just let it die.
All I lost is 100 primers, 50 pieces of brass, and a public shaming. I got off easy.
I'm pissed off at myself for possibly fucking up my rifle, for not doing basic safety and for generally being an idiot and I am supposed to do this to fucking relax and now I'm stressed as hell.
Thank you to all who tried to help--its a PITA to diagnose over the internet. Lets be clear it was an ID-10-T error.

How did it come off if there wasn’t any damage? There must have been some damaged threads or something? Unless it wasn’t actually attached to the muzzle.Launched a SilencerCo Specwar 762 to the end of my indoor range during a conjugal pre-stamp visit. Fortunately I got away with it minus a bit of paint missing where it hit the concrete and a minor enough baffle strike that I'm not going to send it back. I checked the target and the there was a pyramid shaped hole where the bullet went into paper, can you say tumble.
The cease fire and the walk of shame was by far the worst.
Your comments are not helpful at this point. We've had an extensive discussion, I did not set my die up right. Rather than a rather salty response where i can post lude comments under pictures with the measurements, we've already established I'm a dumbass. But a dumbass who knows how to use calipers and has so for many many MANY years.On the sizing issue- how did it end up that different?
Are you one of those people who resets the die adjustment after every loading session? If so, stop doing that, for starters. If you’d set the die correctly for initial load development, and left it alone, headspace would have been spot on or just a hair long due to case hardening but not enough to cause an issue.
And the headspace measurement thing with the wrong bushing - that part only should matter if you’re trying to go by an absolute measurement. It should be a relative measurement, comparing fired brass from your rifle to the resized dimension. Remove primers from the fired brass for this measurement, but don’t size it.
If you’ve zeroed the calipers on the fired brass (measuring a few to find the maximum), then it doesn’t matter where on the shoulder you’re measuring as long as it’s not right at the corners; the entire shoulder gets bumped back the same amount.
On the bullet sliding into a fired case - that .290” dimension sounds like sized brass, not loaded brass. What is it with a bullet seated? It’ll vary a little so measure more than one round, and at different points on the neck.
If your dimensions of .296” fired and .290” loaded are actually correct, that’s .006” clearance and a bullet should drop in easily. If not then you’ve got pinched necks (long cases or fouled chamber) or you’re just dinging the case necks during extraction but that should be easy to see the flat spot.
Also, this is all fairly simple stuff, but I think you may be confusing some of the issues by using the wrong terminology. That makes it hard for everyone else to respond accurately.
No need to get snippy. My comments were intended to help you figure this out, since you don’t appear to have done so yet.Your comments are not helpful at this point.

And I checked it on 3 different sets.
Also every piece of brass I have every fired from every gun is obviously defective as NONE of them allow a round to just 'drop' in the case on fired brass (yes un-resized) brass. This includes 30-30, 30-06, 300 WIn Mag, 300 Sav, 308, 6.5, 223. They are all sitting here in my office.
Would you like me to try 22LR?
Or I have some magical quality that shrinks brass to longer accept a bullet freely once fired. Which includes factory brass. Cause I am mutha fucking talented.
If your neck thickness is .014 and a fired case is .296 then you should have .268 ID on a fired case. Your bullet is .264 but won’t fit in .268.Yeah i've measured it consistently with 2 different calipers.

My apologies if i haven't answered everyones questions exactly, i have a day job and responding in my spare time.
At my age (mid 70's), I find I always have to be extra attentive to avoid Faux pas, but . . . the damn things still happen.![]()
I'm old to and shoot alot,I find if you run to hot of a load 41.5 say of h4350 to fire for new brass is a waste of time I'm with bad eyes with no glasses so I check everything twice then again ladder testing! I want everything perfect so if need be ill ream a new chamber to hang my creed bullet out the case like a 7 mm mag I was a little machinist boy at 16 then after put my self through college and many degrees pursued. A career in education in Elizabeth nj teaching vocational machining I'm my experience your finesse and feel dictates my fit in a build even with custom made barrels the chamber can be to tight Evan for new brass in any dimension, burrs sharp angles lack their of can run havoc! I got go no go gage and use it but it's a not a finish tool it's a ball park parameters! If I got to rent a chamber gauge from Manson tools to finish clean the chamber to my comfortability then I stop shooting right away and get her dome! The manufacturer don't dictate what's perfect I do !If your necks are too long the case mouth will pinch the bullet when the bolt closes.
I make up a dummy rd with no powder no primer set a bullet around 2.875 col est with the ñeck annealed and bullet waxed up I slowly try to rechamber said bullet with in chamber if it fits your your to big if not drop bullet down .010 at a shot till it closes ,don't force it cause bullet will stick in barrel and you'll need a push rod to dislodge it ! Keep records of bullet col and brand graingerYeah i've measured it consistently with 2 different calipers.

I have not done but wonder who can comment: pressing primers: what would happen if a small rifle anvil is used to press a large rifle primer? will the smaller diameter pressing on the large rifle primer ignite the sob?It takes quite a man to admit his mistakes. But you likely saved someone else form making the same. Thanks for that.
We also need pictures so we can really haze you.![]()
If your neck thickness is .014 and a fired case is .296 then you should have .268 ID on a fired case. Your bullet is .264 but won’t fit in .268.![]()
Case mouth = .268The case mouth ID is smaller than the rest of the neck, therefore the bullet won’t drop in.
Case mouth = .268
Bullet OD = .264
Bullet OD is smaller than case ID therefore bullet should fall in!
And it turns out my die is not sizing the case web area to fit a chamber guage.
I find small based dies are the only ones that fit chamber gauge consistently.And it turns out my die is not sizing the case web area to fit a chamber guage.
Really? I thought if i hit it with a FL resize it would go back to spec. Now it is a Hornday gauge (known to be tight). WIth the all the crap that went down, I trying to do everything by the book and check. Its setting the 0.002 bump has givin me fits all over. You tube, articles, searches, etc--I always somehow screw that part up. Some days I hate firearms.That’s not unusual.

Ok no i don't but it sure doesn't help my OCD.
.010 won't ruin your day if your col is accurate powder measurement an bullet selection are more crucial ! Less col is better than more in a semi as to bigger Col jam the gun
Agree, didn't want to get into that discussion here though. I really don't measure COAL unless it's to confirm it will fit inside of magazinesUh, no. If the load is developed for a specific BTO measurement, then .010" can change that. COL is pretty meaningless in comparison, as long as the rounds aren't too long for the magazine.
