Re: need some info on new Barrel buy
First of all, is the barrel you have now worn out? If not, shoot it, as sendero rifles usually shoot pretty good.
If you are set on a new barrel, get a 24" 1X10 twist and shoot the 190's at 3000fps with Retumbo powder.
That is my set up for the 300WM I have.
I like the cut rifled barrels.
