Reading:
"Safety is a big issue for ammo manufacturers, as are lawsuits. Willy is not the authority to proclaim correct answers. Why not write a letter to Winchester, Remington, etc. and ask?"
and
"There's no reason why they don't bother to produce a round with TB other than money and marketing."
Actually, what I said, as opposed to what words people are putting to my writing, is that there is no reason other than business economics why cartridge manufacturers do not load gallery loads as a normally available consumer product. There is 100% certainty that it could be done safely... it's BEEN done safely for decades for military rifle gallery cartridges. Tens of thousands of .30-06 gallery rounds were shot by the good old US Army over the decades... it's not new science.
I also never said that any of them would use Trailboss... any cartridge manufacturer doing this on a large volume production basis would likely use a powder designed for the specific use. Trailboss "as sold by the pound" would likely not be their choice.
Business is Business: Companies make what people buy. That's a universal rule. I stand by the answer that it's commercial decisions and not available powder that's the reason we cannot buy reduced powder charge, light bullet gallery cartridges in our local outlets.
The title of the original post is likely the issue here... the question should be "Why cannot I buy reduced powder cartridges that mimic the performance of what I have been handloading with Trailboss?" while leaving the powder selection open. It was within that paradigm that I answered what I answered.
