My 300 Varminter will be completed soon, so I am beginning to collect parts for this build. I am really interested in the 6x47 Lapua or is it the 6x6.5x47. I am not real fimiliar with it, I think necking down the 6.5x47 Lapua to 6mm is the cartridge I want because it will hold around 40+grns of powder. Anyhow, I am tying to get the correct information. I have heard really good things about how it performs, ect. I am going to be using 65, 70 and 75grn Bullets. I will be using a 30" 1-12 twist barrel. My question is what type of velocties will it produce with these bullets and barrel length. Also, is anyone on here using this cartridge and do you like it? I was going to go ahead and build a 6mmBR, however, I wanted a 6mm with more power. This cartridge sounded like it was the middle ground for power between the 6BR and 6MM AI or 6x284. What is your opinion on this cartridge. W.
