[QUOTE="DB33, post: 138920, member: 5702"] I was wondering about drag function and or BC how to use them. I have been playing with the eskimo program trying to build a chart for my rifle that is a 300 win pushing a 168 berger vld at 3150 mv.zeroed at 300yrds The top of the berger box lists the bullet with a .512 bc I know that the true bc differs from rifle to rife but this is where I started using the g1 drag function and .512 bc I printed a chart using these and went to the range. Started at 8oo yrds and was consideralbly low so I started adding clicks approx 3 min, until I was hitting steel when I got home I played with the drag function but nothing seemed to fit the #s I had for 800 so I started reducing the BC until the #s fit,I am down to down to .450 bc still using the g1 drag function. Is this the right direction to make a good chart or am I missing something else? thanks DB [/QUOTE]
