My first experience with N140 was in a 22-250 AI. Seems all the normal powders I used, while giving good accuracy, my barrel would get really hot ( summertime workup). I read somewhere that the VVN powders gave high velocity with lower pressure, or something to that effect, so gave it a whirl. It was true! ha My barrel stayed much cooler for more shots and accuracy was stelller, from the 55NBT to the 68 Hornady OTM I was playing with at the time. Its a good one for sure.
