Here is my one. It is a Rem Model 7 7 SAUM.
I fluted the factory barrel, fluted the bolt and replaced the firing pin with a lightweight version. The biggest weight saving was making a carbon fibre stock. The stock weighs just over a pound.
The scope is a Bushnell 6500 2.5-16 x 42 in lightweight Talley rings. The scope is a bit heavy, but the magnification range is great.
The bare rifle weighs 5lb 4oz with the rings an scope it weighs 6lb 10oz.
It shoots 140 accubonds into less than an inch a t 100 yds and 162 a-max into 1.25 -1.5 inch at 100 yds.
The only animal shot so far is a red hind at 450 yds with the 162 a-max.
