Fwiw, I think those powder choices would be well down my list for light bullets. N135 is a popular choice with light bullets in a straight 6br. I suspect it'd be at or near the top in the 40 degree version as well.
32.5 of n135 has worked well for me many times as wellI have a bit of VV133 & 135 where would be a good place to start for the aI ? thanks
