Sabotloader,
I too shoot Nosler Partitions 300g, and I too don't like the price increase. I am shooting Hornady XPTs in my Flintlock this season, a friend has had great success with these bullets. I also know that the Modern Muzzleloading book fellow uses them and has had great success. They are only $10 for 100 at Cabelas, so they are cheap to shoot and if their terminal performance is good, what more can you ask for. I like the Noslers, but I hate paying $1/bullet.
