Here we go again with the groups. If by this point, you don't think holding a "tighter, exact spot" at 50 yards versus 100 is better for testing, here is another target with really tight groups. We chose 50 because the groups at 25 with some were through same hole, and its hard to measure anything from that.
Onto the powder. Is this the wonder powder for 223? The hidden gem? Let me take this time to "advise" Alliant company.
Whoever knows Alliant, please pass this on. "Hey, Alliant, I think you could have the "best" powder lineup of anyone out there. But you have one issue for improvement, your load data is very weak. Please, go learn from Western Powders on how to build a load guide. They are masters. Your load data for Varmint? you have like only a few bullets and its near 55 grain only? What about 62 grain, 69, 75, 77, 80 and a few variants of popular 55 grain bullets? You should also list what other powders your Varmint, for example, is "close to" in terms of burn speed. you could do SO MUCH MORE! You have probably the best product, but your marketing needs improvement. Take varmint for example. It could be the top selling powder I think for 223/5.56. Right now, people think its like H335 or something like that. But H335 cannot compete with Varmint "overall". Nobody even knows about this powder. Come on Alliant, lets step up the marketing effort, you can do it!"
