I just switched from a steel 20" M40 contour to a 24" CF straight 1.250 contour and saved around 2lbs. To me, there is hardly any weight difference going from a Proof Sendero contour to a straight contour. I'm more inclined to go for more straight contour Proofs as it looks mean as hell on the rifle.Assume MSPR & AXMC/AXSR 300NM 26” prefit
Carbon Proof Barrel
Cost: $1,199.00
Weight: 3.937lbs
Cost/lb = $304.55
SS Proof Barrel
Cost: $709.00
Weight: 4.75lbs
Cost/lb = $149.26
Difference in weight is 0.813lbs
I just don’t see a good return on investment going to carbon. If it’s a hunting rifle that sees like 10 shots a year then it’ll last a life time and you’ll have < lb of savings so maybe that matters if you’re a mountain hunter. But I’d rather chop 4” off the barrel and call it good.
