[QUOTE="TheLongRanger83702, post: 1144646, member: 88760"] lightbulb I am relatively new to all this but have watched a lot of videos and read a lot of articles about what helps make an accurate rifle. I have bitten the bullet to NOT compromise on quality and create a "weak link" in my pursuit for accuracy. I don't know what powder you are using to accomplish .003-.005 grain increments.
