I have asked the question before but didnt really get what I was looking for. I am getting ready to order so i want more opinions. I am building a 338 Lapua on a remington 700 action. the Donor is a 300 RUM I was planning on going with the PT&G Fluted bolt with the Lapua bolt face and extractor. Then I saw David Tubb Made a custom bolt for it too. his bolt is about 150 dollars more than the PTG set up I want His claim is the bolt is very true and also its a little bigger in doameter for a tighter fit. My question is it worth the money? I am going to use the rifle as a long range elk gun but Also something that shoots tight groups at longer ranges. Will I see the benefit from the tubb bolt with my application? What do you guys think?
