Okay so I have a Bergara HMR. 308 and have just recently been reloading so I'm chalk full of stupid questions but this one is mainly confusion. I see a lot of people talking about how fire formed rounds out of your rifle are best but then they say trim the neck. If after I fire my round my case oal is 2.015 and I'm supposed to trim to 2.005 wouldn't that defeat the fire forming to my exact rifle? Obviously I am resizing my cases but still curious if trimming to 2.005 is best or leave closer to 2.015. With how close im seating to the lands im not getting much bullet seat at the trim length. .015 counts im guessing. What are your thoughts?
