[QUOTE="dirtball, post: 772806, member: 7344"] [I]I would be a bit suspect of the claims of nearly 3350 fps with the 230 gr in a 30-338 Lapua Improved. Must be a very fast barrel. Out of a 1-8 twist, that throws some red flags up. In a 30", 1-8 twist barrel, my 300 Allen Xpress will drive a 230 gr to just shy of 3300 fps and it will drive a 240 gr SMK to 3225 fps using Retumbo. I have not tested RL-33, mainly because its nowhere to be found. [/I] [FONT="Comic Sans MS"][SIZE="3"]Kirby A year ago I would have said exactly the same thing, in fact I was getting slightly less velocity that you with Retumbo, probably not pushing them as hard. I had read all of the hype about RL33, so I decided to give it a try, Two Ohler 35's cant be wrong, Easy bolt lift and no ejector marks. I think you will be pleasantly surprised when you get a chance to try some. It should be a great powder in a lot of your cartridges. What I have read is that it is made by a different company than the other Alliant powders, all I can tell you is that I found it less temperature sensitive and a whole lot cleaner than RL 25.
