This is recommended as one of the very best powders for 223 in the accuracy department but I have ever used it. When I decided to try it I could find none. I have not seen any on a dealers shelf for years. I attended a gunshow last Sunday and found one lonesome bottle of it. When I looked at the price, $75, I just sat it right back down and walked on. I would like to try it but not when most powders around this area are going for $50 or slightly less. I know H322 is very accurate and I have a good stock of it. Experimenting witt H335 will have to wait until I find it at a better price. I know 25 bucks doesn't amount to much in today' money but I am not going to be gouged if I can help it.
