410 enough power?
yes. a 410 slug is powerful enough to bring down a deer, however you need to get within bow hunting range. the drop on a .410 slug is rapid so aim high, I also suggest to use high base shells, hot loads, and you can find rifled slugs I think Federal makes the best ones and they have a plastic pointed tip, those suggestions will certainly increase your range and accuracy, getting up close is up to you, 50yds max. good luck.
