Re: Weight loss for an old friend
Gordair2002, another Canuck!! good stuff.
As to your question the options are fairly limited without going into a lot of rebuilding. The first is fluting the barrel. That can reduce weight around 1/2lb depending on barrel contour. Ron Smith at RKS would be a good gunsmith on the fluting. He is in Calgary at 403-631-2405.
Second would be to hollow out the stock. Guessing that this one has a wood stock. Drill out the foreend and butt, put in one layer of 6oz fiberglass with epoxy resin to seal and to stop splits, fill with expanding foam (home crack sealers - Mono). The stock work could reduce another 1/2lb.
you could also see if there are any composite stocks made for your rifle. They tend to be around 16 to 20oz so would save a lot of weight and are durable against horse and scabbard. pricey though.
Beyond that there is fluting the bolt, machining the action. That gets expensive.
You could also look at a lighter scope. A fixed power is usually lighter. Now we get into hair splitting like lighter rings, trigger guards, etc. Probably save a few ounces overall.
The T3 sounds like a great way to go and light out of the box. That Sako may be better as a platform for a LR cannon.
