So after firing some of my brass 5x (260rem) in my savage i noticed the heads were doming out. I checked the factory bolt head and it was starting to dish out. I ordered a ptg and put it in. My go guage closes with no problem but before with the factory head a 1.632" guage the bolt wouldnt close now with the ptg a 1.632" closes half way and a 1.633" wont even com close to letting the bolt handle move. Am i ok or should i reset the headspace?
