Just been through / going through now.
300win in houge stock - had load sorted and was shooting very nice.
Changed to MDT chassis - same load was okay but no where near previous.
Took a range of reloads to start development again and it appears - the best load now is .8-1.0 grains more powder.
Interesting to me - I tried to see where / how much of action was touching vs chassis / stock - as it seemed 1,0gns is too much for harmonics alone...but it is what I’m seeing...
