I like the converted or PTG bolt with the M-16 extractor a lot better than the factory extractor. It's a common job. We get a better than factory fit on the head of the case. I like to use an M-16 extractor after opening the bolt then alter the feed rails with a diamond home by hand. This gives us super dependable extraction without the danger of a Sako style blowing into your eye if anything goes wrong.
With the 195 Berger it is very potent and being 7mm has a huge choice of bullets for about any occasion.
