HLDeerHunter.........
You just stated you wouldn't try a moose with a 30-06 more than 100yrd.......why is that. I would try a moose anywhere within 300yrds with my '06 and I know it would drop him very eithically with a well placed shot. I wouldn't shoot anything much further than a 100yrds with a 30-30 however.

You should check some ballistic tables .......150gr hornady IB, 3000ftp@muzzle, 2 inches high at 100yards is 7.3 inches low at 300yards with lots of drop down power left.

what makes you think a moose, deer, elk or bear is going to survive that within 300yrds.

just looking for your reasoning behind your statement
