Dropped my Varget charge by .5 grains...

[sosicmcise]

Quick question.

I reduced my Varget charge on a 175 SMK load by .5 grains (originally 42.5g now 42.0g) The 42.5g load shot at 2644 through a 3 screen, indoor oahler chronograph. What ammount of velocity reduction do you think I'll see with a .5 grain reduction?

Any thoughts would be appreciated for those that shoot w/ Varget and 175 Matchkings.

My WAG: 15-20 fps / .5 grain change

But here is an interesting link:

Why did you change your load? When I read the title I was expecting to see you say the speeds were the same with reduced load, as in lot differences. I have seen a .4 grain difference between lots.
