"Now onto cans. What does everyone like for bolt guns? Obviously overall weight is a factor for hunting. "
So, heat is a problem with suppressors. If you are firing a lot of rounds quickly, you need to use spiffy materials - titanium, iconel, yadda. Those are heavy and expensive.
For a bolt hunting gun, if you are willing to shoot slowly enough to keep the can below its temp limits, you can use cans where much of the structure is aluminum. That makes them light and relatively cheap. The downside is if you don't watch the rate of fire/can temp you can heat them to temps where aluminum's strength falls, and Bad Things happen.
I haven't been keeping up with current offerings, but two to look at might be the Gemtech Tracker and Griffin Sportsman. They are around 11 ounces and $500/$600,
For contrast, the Sig SRD7.72 is 15 oz/$600 and the Sig 7.62Ti is 17 oz/$1k.
FWIW, my general opinion of cans is sort of like the 'which pistol is best' discussions: no can is to any can like unarmed is to armed. Given the price and wait, by all means shop carefully, but whatever you get will likely work well.
