I agree with others, you really need to check the headspace.Is this a newly chambered barrel? If so and the gunsmith is nearby I would have him check the headspace.
If you can't get to the gunsmith and don't have a head space gauge set you can use some cellophane tape. Trim the tape to fit on the case head of a new cartridge. Add tape till you get bolt closure resistance, then measure the tape to get an approximate measurement. If it is over .005" the barrel should be setback.
