Its a lot lighter than a chainsaw
Thats the answer i got when i asked a hunting partner who was carreing a 220VT around some rough country a few years ago how he could carry that beast around all day=He logged for a liveing!
Putting a McMillan stock on is gonna make it a sweet looking unit and will be just as durable if not more so than the laminent BUT its a lot of $$$ to save a pound, maybe a pound and a half at the most. The weights in the barrel! Putting a sporter stock on it will make it balance poorly and only save you a few ounces BTDT
Might be a good time to add another gun to the arsonal that carries better and save the VT for use closer to the truck
