Savage model 10 hard extraction 6 creedmoor

[pdog06]

The 6.5 cm die shouldn’t have touched the shoulders of your 6br brass cause it’s much shorter? If anything I think it woulda made the Oal of the br brass a tad longer?

I just use the 45acp sizing die with the decapping pin removed. One pass takes my brass from .4703 to.4699 at the .200 line. Then run through my regular sizing die.

Would the length of a creedmoor come into effect ? It’s longer than a br.

I’m shooting a 6 creed. Not a br

When you have a hard time pulling out a case, and then that case will only go back into the chamber part way after sizing without force, then we usually find we have a diameter coordination issue.

I can usually cast the die and chamber and sort out the issues quickly unless the barrel isn't easy to remove, but unless you have that capability I recommend you get a little assist from a qualified rifle smith.

No smiths around me

Sorry bout that DLT I forgot you had a 6cm. Now it makes sense…lol glad you got it figured out.
If you don’t want to bump the shoulders you’d need to use a long action caliber die like 25-06/270/30-06.

I am curious if those pcs of brass spring back after firing to a hard bolt lift again or if they come out fine? Time will tell for both of us on that…lol

 

[DHuffman]

I’d like to know which ones. This one leaves a lot on the table

The best one I ever had in this regard had a stupid long handle and a knarly knob. Came on a gun I bought used.

I always meant to try and source shims to go over the bolt body between the handle and big rear bolt assembly screw. I think that would work if the shim held up.

Ha no worries. I have tried that. For those who don’t know a creedmoor will not even go halfway in a 30-06 sizing die due to the taper

Here's a question... one for those who know more than I:

What about the shoulder radius? Could that be too sharp for the chamber, causing it to interfere? When you bump the shoulder, it would make it sharper than the chamber

Savage barrels are one of the easiest to R&R, but if you haven't already done it or don't have the tools, then it could turn into a lot more to bite off.

I tend to try and get the chamber and die measured up before I would ever recommend taking any non-reversible steps.

When you already have the tools and gages, pulling a barrel and making a cast isn't expensive. If you don't already have the vice, wrenches, gages, etc., then it isn't the same.

What about the shoulder radius? Could that be too sharp for the chamber, causing it to interfere? When you bump the shoulder, it would make it sharper than the chamber

Another reason we often cast the chamber and the die to see if there was an issue with how those were cut.

When you have the ability to inspect and to cast, you just do it. If there are lots of alternate known good dies laying around, you can try them.

It can take a single cycle to have a difficult extraction in some instances, but in most rigs it takes several cycles for brass to fully form to the chamber. The OP's description of the problem is the most common type, where difficulty happens after several cycles.

The Lee carbide 45acp die I have has roughly 1.845” of straight wall so that should be plenty of room for the creedmoor cases. I ran one of the girlfriends creedmoor cases into it to check, no problems. That being said it sounds like you have a classic case of clickers. They will chamber fine with no noticeable issues, it’s only when extracting that it is noticed. The best fix is to get a die that sizes the base while not over sizing the rest of the case.

I’m assuming you lube up the case ?

Nope, it only touches the bottom 1/2” or so of the case. I haven’t had a need for lube. I’m sure it wouldn’t hurt though.

Good deal. I can get one around $25 to try. It’s a factory barrel but it is a sweet shooter. Really don’t want to Take it apart or buy custom dies that’s only good for this chamber. It might be the way to go. For sure worth that if it was to fix.

Lee 45acp dies are carbide, no lube is neccessary.

On my 4th firing of my brass while shooting distance on sunday I noticed I had to wrestle with the bolt to get my fired brass out of the chamber, not super fond of how savage does their primary extraction. The bolt handle makes contact halfway down the ramp of the baffle. Have not noticed any such problems on the previous 3 firings. Details

6mm creedmoor 26” barrel
Anneal prior to sizing every firing, adg brass partially through 4th firing
Federal 200 primer
39.5 H4350
Sierra 107mk
2975 fps
Fired case - 1.537
Sized case - 1.536
Redding full length sizer

My fired cases are a little snug to get back into the chamber have to get firm with bolt to make it close. My sized cases go in easy and will come out on their own with rifle tilted. Maybe a little advise from people who have had the same issue Thanks in advance

The Sierra manual for your 107 gr bullet gives 39.3 gr of 4350 as a max load. Your at 39.3 gr. Did you ever consider less powder? Don't you think a hard bolt lift is a clue?

You said something about having to tilt the rifle to get the empty case to drop out of the chamber.
Sounds like your ejector is either gone or seized.

I wouldn't mind seeing a picture of the bolt face and the brass head stamp.

I also have a mod 10 FCP-K that had issues extracting after firing. I ended up polishing the chamber with the last section of a 3 piece cleaning rod attached to a drill and a chamber mop, progressively using 3 different polishing compounds on the mop. Starting with the coarsest (still a very fine compound ),... to a medium and finally the finest compound. Then cleaning the chamber.
It worked and solved the issue.

Im going to polish it, I just stated that comment to show I had them sized enough. I don’t have to tilt the rifle to get them out the bolt grabs the case head with no problems

I used the hodgdon load data. Theirs claim 41.3 in a winchester case with 24” barrel is running 3009

I’m at 39.5 with adg brass which does have a smaller capacity running 2975 with a 26” barrel. If it was hot wouldn’t it have shown up in the previous rounds. I have about 175 down the barrel. I recently went from the hornady 105 to the 107 smk with no other changes. It shot much more consistent at 800

Looking over my brass the body shoulder line is pretty sharp, doesn’t seem to be any radius at all

I didnt notice hard extraction with the 105s on the previous 150 rounds first, second or third firing of the brass. Tried the 107 on the fourth firing and mostly all of them was difficult. Is it the brass because it’s growing or could the bullet change have caused this issue ?
