    I just caught wind of those bullets too. Never knew they made a 175gr vld for the .270! I wonder how that will affect barrel life though... I am going to email the company and ask them if they have any of that information to send over.

    Not sure if Bryan has gotten around to this bullet yet, but the cacl G1 bc being 0.7381 it's close to their 168gr 7mm VLD which has a calc G1bc of 0.7136. I spose you could extrapolate and get pretty close (not exact) using the measure G7 bc of the 7mm 168gr which is 0.311 (berger 168gr VLD is 0.316) and apply <-- that to the 270 165gr. I figure it'll be in the neighbor hood of 0.315 - 0.325. Perfect? no. But I bet it would get you in the park

    Post number 24 was an estimate. I have tested the matrix 175 here is the info for my testing.

    G7=.3225

    G1=.6435

    My friend who has a similar test method as me has tested the 165 matrix at the following,

    G1=.638

    That would make the G7=.319

    Good luck, make sure your scope tracks when your figuring out your drop data, if the click values are off on your scope it will mess up your solutions from your ballistics program and you will be chasing velocity and BC numbers trying to get it to match.
