Since the supplies at ALL my powder vendors are severely lacking, I am exploring the option to try out the Viht N140 for my AR10 gas gun .308 shooter. Krieger 22" 1-11 twist SS Heavy barrel. We have been using the R15 and Varget powders with great results. Does anyone see any reason as to why N140 or possibly N150 wouldnt do a great job as well? My local vendors actually have it in stock. By the way, I shoot 178g Hornady AMAX, 175 SMK and will be giving the 185g Lapua Scenar a try. Any help would be greatly appreciated.
 
N-140 will get the job done and done well. Good to go. Get a pound and give it a go. N540 good as well, especially for 308 applications where some extra speed is required.
