...but Ramshot powders have always been very hard to find around GA, so I've never seen it to buy it.
And this is probably the case. I buy Silhouette online, but I don't think I've ever seen any Ramshot powders on the shelf in a store. It seems brick and mortars have more Hodgdon and Alliant than anything else.
Now that I think about it, there is a conversation I have had over and over and over at the range when someone sees me testing loads:
"What powder are you using?"
"AA2." (or N320, or Prima-V, or any of a number of other powders I've played with)
"What's that?"
"Fast burning powder. I'm loading for 9mm minor for IDPA/USPSA."
"Oh! I use HP-38 for that. That's what everyone uses."
Some version of that conversation over and over, and now it dawns on me -- that's what's available at the local shops. Lots of old-timers don't like to buy online. That's also the reason people comment on my wasting money shooting hollowpoints -- because they don't have PD in the local shop at 9 cents per round. Or why people see me with coated bullets and ask what the heck those bullets are. Why are your bullets red? What's the purpose of that?
The local shop has Hodgdon, FMJ, and plated. Funny that hasn't dawned on me previously.
