Savage 110 flat top receiver made in 1993 for .270 Win
when I chamber a fire-formed case the bolt closes real nice.
After resizing the case it is hard to close the bolt. I took measurements of the resized cases and they match the SAAMI specs found in my Speer 14th book.
when I run my winchester brass through my RCBS full length sizing die it fights me almost to the point of being a stuck case during both the up and down ram movements (herters super model 3). I have the die set to just kiss the shell holder and the decap pin is just shy of 1/4" below die base.
If I remove the bolt and drop fireformed case into chamber it wants to bind before it fully headspaces. If I do the same with a resized case it drops in and out easily. I then took the decap-expander out of die and had the same press binding issue. If I take the case that has been resized without the expander and put it into the chamber it drops in and out freely.
Last winter I forced the brass through the process and did a ladder test using JLA's procedure. Even though I had issues with hard bolt closing I continued and found a load that ended up with .7" grouping at 100 yards.
should I have it checked for a out of spec or damaged chamber? Should I look into neck sizing only? I don't have any factory ammo to try but I can find some tomorrow.
