I was testing my first batch of reloads and my new chrono.  My first reloads where a little slow.  Ill have to add a little powder.  25.5 grains of wc844 and a 55 grn bullet got me 2650 fps avarage.

A rather unimpressive showing for winny white box.  Those figures are all over the place..

Q3131A seems a bit slow.

You know, that Chrony looks just like mine.



Before I shot it.  Twice.

I ordered the Master Chrony for that very reason...I expect to do harm to it eventually, but hopefully not horrendous harm.

So how did you set up, and what was the weather like?

I put it on the ground and laid down 10 feet from it.  I couldnt use my shooting table because it wasent long enough and its under some big oak trees and the instructions say not to have it set up under a tree.  I guess the branches will effect the reading.  Clear and windy about 70 or 75.
