Why would Alliant ever change the burn rates?Just saw a advertisement for a cleaner burning Red Dot and Green Dot powders in my current Handloader Magazine. Anyone seen or tried this out yet?
Wondering if burn rates are going to be different.
That had nothing to do with the "New Green Dot" Alliant dropped all the 7/8th loading data years before the packaging change.Green Dot did change. I know a few people that have been using Green Dot in their 20 ga tubes for years, then cracked the tube(s) when the loaded the Cleaner Green Dot. Also it is interesting that Alliant dropped all 7/8 oz 20 ga Rem and Win hull loads the next year.
The dropping of 7/8 oz. green dot 20 ga. load data had more to do with defective 20 ga. tubes in 12 ga. guns than it had to do with any change the green dot formulation.That had nothing to do with the "New Green Dot" Alliant dropped all the 7/8th loading data years before the packaging change.
I load 20ga Winchester HS hulls,Yes,
I never stopped loading Green Dot in
20 gauge AA HS hulls.
One could draw that conclusion."It was an Alliant Book Load..."
Your 20 ga tubes have not cracked, so as Nebs posted, those that cracked were most likely defective.
