I have decided to purchase a HS Precision PHR Rifle and was wanting some input. I want to know what would be the best all around Caliber for hunting all North American Big Game. I was thinking about a 26in BBl with a muzzle break installed. I plan on going sheep and goat so I dont want a real heavy rifle either, but also want something to cleanly kill a Grizz. I know shot placement is everthing and I am very confident in my shooting ability. I would like to stay with a 30 cal or smaller but am open to sugestions. I am looking to shoot no longer than 600 yards. I am just courious at what input I will get. Thanks Joel
