I am almost out of Sierra MAtchkings for my 260 and i was going to increase the weight from 120 to 140 garins. While Iw as looking around, i saw that Nosler is now making their competition bullets in 6.5 in 140 grains. Has anyone used the Nosler comp. bullets? How would you compare them to the Sierra Matchkings? The most important question is can you get them in Canada?
