I was not going to get on this, but OH WELL!! If you want to use H322 buy 50lbs of the "SAME" lot number. If you want to use V-133, do the same, an powder do the same. Then take the time to learn to shoot it. Learn how it works, learn it's little secrets. Pros, if it is good you have 50lbs of it, if it is bad, as to your taste in powder, you bought 50lbs at once for a reduced rate sell the rest off at a profit. Every time you buy powder in 8lb kegs you will get a different lot number and each one will have it's own character and you will never shoot worth a dam. Example 1991 H322 was fast, 1992 a tad slower, 1993 slower again, 1994 and 1995 were so slow you could catch them in your hand, well they went back up to 1998 which had the same HP as 1991. V133, in 1997 I bought a keg and shot it for a few years, loved it. Bought another keg in 2001, tad slower but really workable. Bought a keg of 2005 and got rid of it a month later at a profit, bought another keg 2008 which I still use. The problem with H322 it is a fast powder and with V133 being a tad slower it is easy to tune. Go to the range start at 53 clicks, then 54, then 55. With H322 start at 48, 48.5, 49, 49.5 but don't go much higher. And if you have worked with that particular powder you will know when it has reach it's peak and when you can go up a tad. H322 is a good powder, just takes more tuning but your groups will tell you what to do.
