PLEASE READ:Maybe the neck just needs to be trimmed back to spec???
If You measure the head with a pair of quality micrometers you will find your cases head dimension is most likely +.002" +.005" Over Size. This can be attributed to several issiues which I won't go into here, however you will solve your initial problem by following along.
Initially start with virgin brass and set aside all your fired brass so that you can make a fair assumption of the following procedure !
Apparently your brass is conforming to your chambers dimensions which may be slightly larger but still within Sammi Specs..
The solution is to reduce the brass at it's base to where it will chamber in your rifle easily.
First do you own a cartridge Case length gage in .270 Caliber?
If not please I suggest that you purchase one in this caliber. (see below)
Next purchase a Redding body die. (caliber specific)
Now if you want to bump you shoulder at the same time killing two birds with one stone purchase the Redding #1 competition shell holder set.
Combining these two items will allow you to fit brass cases
(A) To completely ensure a perfect case to chamber fit.
(B) It will bump size your shoulder back -.002" or more as you see fit. all in one continuous operation .
The best part is you do not need to waste your valuable time playing around with your FL resizing die in order to get your correct shoulder bump.
Simply by setting the Redding Body Die ONCE , and use of the Redding Competition Shell Holder Set #1 plus the stepped and numbered shell holders included in this set along with your rifle you will establish a custom fit that works in your action.
(You can U-Tube for videos on this)
Now another plus is that you can use this same Redding # 1 Competition Shell Holder Set on Any and I repeat Any Caliber Case that is in this family ie, . 22-250, 243, 6.5 Creedmoor, 270, 308. & 3 0 -06 + any wildcat cartridges using this parent base
( NOTE: You Must FL resize your your cases, and trim to length as per your norm first before using the body die)
By using this system You No Longer will you be plagued by rounds that will not feed in your rifle !
I use this Redding Body Die Combination as stated above on every rifle that I shoot ( most fortunately fall into the category #1 Redding Shell Holder Set) and can attest to it's ease of use as well as functionality.
OBTW The Case Length Gage will determine if your cartridge cases will fit in your chamber easily as well as some of these gages will check your cases O.A.L. depending on which brand that you purchase.
Hope That this helps.
Just my 2 cents worth !
