I have a Remington 350 magnum in a model 7 cdl wood stock.
I loaded up two different weight bullets 225 nosler partition and 250 nosler partition
the 225 s are supposed to be going 2550 and the 250 are supposed to be 2470
sighted in at 25 yards for a bear bait the 225s shoot to the left about half an inch but the group is all touching
the 250s are dead centered these aren't all touching but are close
I am using a rest and form is not the issue , I was thinking maybe something to do with the faster speed of the light bullet and the guns twist.
cartridge over all length is the same for both weights any ideas why one load shoots left
