When using mono's for deer, I usually drop down a size in weight. So, the 120g TTSX is great and a 130g is a heavy weight for me.
Also, we shoot hogs, and hogs are a great bullet testing medium, and quartering shots on hogs are very interesting. 129g Hornady SP will not let you down if you like old School bullets that just work, so are the Sierra 140g BTSP.
Unless I was hunting moose, I would never go 140g on a mono. Also, the 140g Hornady Sp is one heck of a tough bullet, and I rate them too tough for deer, as I like to see more expansion on deer.
For Mono's on deer/hogs, the 120g TTSX is a great way to go.
