increased powder charge

[wjarrell]

I was shooting 168 gr berger with 42 grains of varget out of my 18" barreled 308 with sub moa groups. I was able to increase the powder charge to 44 grains and still get sub moa group without showing any pressure signs on the casing. Any idea how much velocity I gained if any with the 2 grains of varget out of my 18" barrel?

QuickLOAD puts it at around 110 fps difference, but it can vary some depending on which 168 grain Berger bullet I choose and what make of case's capacity I choose and what COL I use.

Hodgdon's data says 46 grains is maximum with the Sierra match 168 in a Winchester case, so it's no surprise you are not having a pressure issue.
