If a handloader is trying to achieve 100% load density through powder and load choice, how does one focus on a choice among different brands of powders with similar burn-rates without buying each brand to make the comparison.
Is there a volumetric chart available that compares proportionate displacement for the different brands?
Failing that, has anybody gone through this with R-19 as their initial powder choice? What are the next similar powders on both sides of the density scale? I just know that many of you have gone through this before!
Sure would save me time and money in knowing!
