Re: 6mm-06 project, any tips?
The 6.5-06 standard or Ai version is going to have better barrel life than the 6mm-06 standard or Ai simply due to the 6.5 has a better bore to case capacity ration which basicaly meens its not as "overbore" as the 6mm.
In either case you should be able to get 1500 rounds thought it before the accuracy starts to go south to bad thats if you don't get the pressures crazy and the barrel hot enough to cook on.
With the 6mm-06 with a 26-28" barrel with a 1-8 twist you would be able to shoot the 100gr class target style bullets which would get you to 1000yds pretty easly ,balisticaly speeking. The 6.5 will shoot the 107gr Sierra Match king a good bit faster than the 107gr SMK in the 6mm and that light bullet has a pretty high BC for what it is and you shouls be able to get pretty close to 3000fps with the 140gr class bullets depending on you bullets and the 140's have a BC that alot higher than the 6mm's so its not gonna have as much trouble in the wind.
But if as far as your gonna be shooting is 500yds then I would personaly go with my new favorite the 243Ai , you'll get longer barrel life and if your shooting a 75gr class varmint bullet then it'll be super flat out to 500yds or the 55gr pills at well over 4000fps. and to top it all off my 243Ai will shoot off the shelf 243 ammo into the 3/4" range and after say 200 rounds you throat gets worn then you can simple have it rechambered to 6mm-06 Ai then shoot that ill its gone and at the end you can post your data on both rounds out of the same barrel and see what you liked better.
their just somethin else to think about
