[QUOTE="Rflshootr, post: 1842657, member: 10284"] I was going by some load data and velocities. The powders other then H4831 give good velocities and should be fine for your barrel length. H4831 will probably not give as much velocity, but I have seen some '06s shoot some phenomenal groups with 150's. The powder will get consumed in a 22" barrel, but like you said, it has to do with the pressure curve. I suggested those powders thinking you may have some on the shelf that you've already paid for. If you need to buy something else, I would also look at IMR-4350 which is very close to H4350. Re-16 or RE-17 are also very close in burn rate. The only real way to know is to try different things until you see what works in your barrel. I don't worry about velocity (with-in reason) as much as I do accuracy. And here is hodgdon's most updated chart...

Go figure. and to add insult to injury, Nosler lists RE-19 as the most accurate powder with their 150's....... [/QUOTE]
