[scooterman27006]

my object is paper and i dont see that changing in the near future and my range is seldom over 100 yrds and i have several guns that do well with this even the 17hmr with factory stuff but if i had a 700 action and wanted to pay a gunsmith around 150 bucks to put a 300 dollar barrel in 6 benchrest on it and he is supposed to sell me the dies for it also well im looking at having say 300 in the action and 300 in the barrel and 150 labor plus another 100 for the dies then will i have a real shooter for 100 yrds or more for less than 900 dollars plus add a scope - is there something i am missing here because this seems too easy but a buddy of mine says he can get it done for me for about that price- i already have the action from a 700 adl - anyone suggest another option cheaper or maybe another caliber - buddy says that i can buy the right brass and 107 gr bullets and 100 to 300 drive tacks with it - i have never heard of this caliber even but i have read about the 6ppc but all that is new to me - all i know is its way out of my league but i sure like the sound of it so if anyone knows about this kind of stuff or the caliber then tell me more and please make suggestions thanks scoot
