Reloading for 270wsm
I have an older. Sako fin light in 270wsm. I have reloaded for this for about 10 years, I have never been happy with the way the bolt closes on my rifle when I have a cartridge in it. It is very hard to close the bolt. I have been using a Lee resizing die, I am wondering if it isn’t resizing the case the full length. I purchased the die because it was much cheaper than other dies. And I am wondering if this also could be causing accuracy issues ? Also, what other dies would you recommend to solve this problem ?

Id start by using a stiff nylon brush and patches and solvent and carefully cleaning your rifles chamber and throat,
Id accurately measure the case and make damn sure its sized to spec
especially length, shoulder and base diameters,
then load a DUMMY cartridge and coat its outer surface with black marker...
chamber the dummy cartridge and extract it look for unusual surface rub marks
its not rare to find a reloaded case is not to spec or a dirty chamber
and a case reloaded several times might be too long in over all length

Id also recommend RCBS, REDDING OR FOSTER DIES

Have you ever tried factory ammo in your rifle? If so does it chamber easily. You may have a rifle with a very tight chamber but still within SAAMI specs.
I believe I know what your problem is just by the nature of your post. In order to prove it you'll need to answer me a couple questions.
1. Did this just start recently with your reloaded ammo?
2. Was this brass fired out of your rifle or a different one.
3. How many times have you loaded this brass?
4. Have you ever trimmed your brass?
The dimension for the length of your brass in the attachment Hardcast put above (2.100") is critical for chambering your ammo.
When you fire your rifle the neck of the case gets extremely hot from the burning gases. This heat plus the inertia caused by the recoil of the rifle causes the brass to flow forward ever so slightly each time the case is fired. It also causes the mouth and neck of the case to become extremely brittle over several firings.
This is the reason why trimming the cases are necessary as well as occasionally annealing your cases. If you measure your cases and they are of the proper length then you may have to break out your wallet and buy yourself a small base resizing die. This die brings the case down to SAAMI minimum dimensions.
Please let us know how it works out.
