Kenneth, prudent to start off at 41
Understood, Been shooting the 140 Berger Vld and worked up to 42.9 with no issues,
It certainly clearly shows a preference for 42.6 with the Bergers, I'm just assuming this barrel likes around 42.5 with the 139/140 class,
And yes, starting around 41.5 working up in .2 increments, 10 loads from 41.5 to 42.9
I questioned the upper 42 grain loads myself, most reference materials say I'm too hot, but numerous other people have stated the same results in their guns.
It shoots the Bergers so well, I'm not real sure why the need to continue on looking for improvement,,,,
