I have a custom .280AI. It cost way more than a CA Ridgeline with using an R700LA. It weighs 6lbs 12oz w/o scope. 8lbs 13oz all in. It shoots mid/high .1s with two different loads.
R700LA w. CF tac knob, alloy bolt shroud, fluted bolt, TI firing pin
26" 1:9" Proof Sendero Light plus Hawkins 3 port brake
Manners EH1
Rem factory alloy BDL
Shilen Match trigger
I have shot two different CA Ridgelines in .280AI. Both shot high .2s to low .3s. Cheaper, slightly lighter if I remember right too. I have shot 5 or 6 other Ridgelines in different chamberings as well. All shot sub .5 MOA pretty easily with good handloads.
Is saving money and having the same rifle as 100s of others is worth giving up .15" in accuracy, go for the CA. They are very good shooting factory rifles.
For me, I like my one of a kind tack driver.
