6x47 lapua 115 or 105

[astro]

Is there really any advantage shooting the 115 Berger or Dtac over the 105 Berger or 107 SMK? I've been shooting the 115 Dtac, but so many people in my f-class group are shooting the 105 Berger with great success. I'm not good at figuring up wind drift, velocity, and coefficiency. I know a lot of you are though. Thanks for any help.

I ran some numbers on this last night with 115@2650 and 105@2850 and there's nothing in the numbers that shows any advantage for 115.

Get the best of both worlds. Go with the new Berger 105 Hybrid. BC equal to the 115 grain VLD without the finiky seating depth issues of the VLD.

Would those two bullet weights be 200 fps apart?

Got me, those numbers I'm assuming came from Quick Load or a similar program which I tend to take with a grain of salt.
I'm running the Berger 105 Hybrids at 2940 with no pressure signs what-so-ever. My case head expansion is .00085 well below my self imposed .001 on the first firing. My load in my 6BR shoots in the high ones, low twos.
