I have read a couple comments on this powder that says it corrosive or that it's hard on barrels. Those that use it , is this true?
They stated the older the powder gets the hotter it getsNo, nothing unusual about VV powder compared to other modern smokeless powder.
They make single base and double base powders that are competitive with the same versions from other brands.
Several VV powders are considered best in class, so I don't understand where those comments are coming from.
Double base powders means that instead of just nitrocellulose they add nitroglycerine. Nitroglycerine adds energy or "heat" to the combustion that can add pressure, wear, and heat. But that is true for all double base powders.The 500 series
There can be some truth to this in terms of how powders can age as the solvents outgas over time.They stated the older the powder gets the hotter it gets

Then I would check the published recipes and give it a try. If folks are trying to talk you out of VV as a brand, then they are being silly.I'm looking for some that would be good for 7mag-7prc.
Yep.Then I would check the published recipes and give it a try. If folks are trying to talk you out of VV as a brand, then they are being silly.
Their numbering system is a little different, but not hard to understand.
A 1XX is a single base, a 5XX is a double base.
