selecting when to shoot and when to pass is not difficult. hunting in brush is an art form and requires more passing up shots than taking them. i am all about single bullet kill shots, bamm and down. that means i will pass up a shot if i can't accomplish my objective. brownies in the vicinity require a different mindset no matter the caliber, you had better be a dead eye because they are built on the same blueprint as the A1 Abrams tank.In heavy timber where your shot is more likely on the order of 100 feet than 100 yards and you might get a visit from Mr. Fuzzy, I'd much prefer it to your 270. A rifle that handles quickly, has fast follow up if needed and throws a big bullet is a good choice in heavy cover with or without bears. I know folks who use them to shoot little blacktails.
437 grains in a ounce...583 grains per ounce, velocity is definitely a factor. Us govt loads were 405 grain, I bought a mold for those, at 1800 FPS more or less, was not uncomfortable to deal with. I shoot jacketed 300 grain as the velocity is pushing beyond what I would like to shoot lead. Less recoil with the 300’s.
