I did a ladder test 2 days ago and I need some help with the results.I forgot my chrony that day but yesterday I did some poa/poi shooting over the chrony and wrote down the #s. I know a lot of it is me and any help you guys can give would be appreciated.
The rifle: Trued remmy 700p with 23inch Krieger barrel sitting in an AICS stock with a zeiss conquest 4.5-14 mildot scope.
The load: 178g A-Max loaded with 44g varget. virgin remington brass full length sized and trimmed to 2.005 with Fed gmm 210 primers. Coal is 2.836.
Heres the ladder test.

Re: Ladder test and target critique

Shoot groups of 5 or even 10. Let the barrel cool down as much as your patience dictates. Cleaning it between groups can often give you sometime to do and the evaporation of the solvent sometimes helps with the cooling.

Use charges that are closer together, i.e. 44, 44.2, 44.4, 44.6 etc.

What you have there, it is very difficult to ascertain anything from. 3 shot groups are probably too small to really mean anything unless there is a big swing that is predictable.
 
Re: Ladder test and target critique

What distance did you shoot these at? Hard to say but your load may be between 43.5 and 44.0. In those 2 targets the vertical seems about the same indicating that the barrels may be at the same point of the vibration cycle when the bullet is released.
