Very cool! I would be curious to hear how that Sierra works for you. I load the same in my 30-30, mostly because it's what was in-stock when I went to buy bullets, but also because Sierras always seemed to have a reputation for good accuracy. Plus I figure at just a tad over 2,100 fps, 170 grains of most any projectile should work just fine. I'm new to the 30-30 game and have yet to have an opportunity to take game with it, but I'm eager to get things going!
