Agree about wound channel, a lot of expansion and excellent explosive penetration. If you shoot 300g XTP or Gold Dot for target, and then use 300g Barnes Expanders for hunting, to me that is the ultimate strategy that keeps shooting inexpensive and affordable. Most people are only killing a few deer a year, so a great bullet is not a huge expensive for hunting, also they are on sale at Knight:

Cutting up deer honestly is the largest expense for me every year, not bullets, I spend over $500/year on cutting up deer. For people who are trying to minimize costs, every component of hunting can be done quite cheaply if you buy in bulk and buy off season. Example stands are on sale every year for about 1/2 off at iDcks on National Hunt Fish Week 3rd week of Sept, I bought all mine over 3 years there, and then improved them. Powder at Walmart after the season can be stock up on. Bullets also at Walmart. 1000 primers at a local shooting club or skeet range. Cutting up your own deer. I believe Bullets are the most important hunting component in MLing, since they are the things that are doing the job of killing effectively. Just a few things you should think about as you choose MLing components and bullets in particular.
