I have some 130 grain FMJ rounds for 9mm. The reloading books I have recommend Vihtavuori Powder. I think it is made by Lapua. Question, rather than buy a 1lb of it for the few rounds I have, is this powder comparable to any other powder? If so, great. If not, the powder I am looking at is the V-N340 and that can be used in 9mm and .45 acp.
