Cabela's only has 120-180

but their store up there in Michigan is Cool now that I see they sell tracer rounds I'll have to go back lol
[quote]so when would you go with a heavier grain slug?[/quote] 180's big enough for anything up to bear, but yeah basically the bigger you go the more stopping power or hole makeing power

The other thing is (with 30-06 anyways) bigger grain shells don't go as far so even though they can do more damage,they're safer to shoot. If that makes sense? Like I shoot my 30-06 on private property thats only about 2 miles wide, once I get 1/2 mile off the road to be safe and legal ,the range of 160 grain (or less) shells is about 1.5 miles makes it questionable to if a target gets missed it could hit something else but 180grains are supposed to drop down in range to under a mile 220's supposedly drop to .5 mile in range.If you hit something a 220 will shred it so they're about worthless for hunting but it's less to worry about as far as shoot throughs and acidental over shots.
Since Ohio hunting riffle Laws SUCK I don't worry about what shells are good for hunting,I use my 12gauge for that,unless I go hunting somewhere else.
