I have been loading 308's and some of the rounds are chambering kind of tight. It pushes in the chamber no problem but, some not all, are kind of tight locking the bolt down. I notice it more on my second reloads more than the first reloads. I'm trimming them to 2.005 and seating the bullets to an overall lenth of 2.800 for the 168MK's and 2.775 for the 150MK's both Sierra. I'm using a RCBS competion die set with a full lenth sizer.
I've measered the thickness of the round compared to a factory one and the sized round is around .002 to .003 of an inch thicker at the base and basicly the same where the bullet is seated.
Will this damage the gun? does it put to much stress on the bolt? It's not like I have to force it but it is tighter than a factory which is almost lose. They are also shooting very accurate.
