MontanaMuley,
Ridgeline shot good after some load development, but it took a while (and money) to get there. The factory chamber was REALLY tight on the Ridgeline as well fwtw. Literally every load I tried in the Havoc printed sub-moa. I'm convinced I could have dropped a Black Cat and a ball-bearing down the barrel and got MOA groups in the Havoc. It's just stupid accurate with 180 VLDs in my 7mm Rem Mag out as far as I've shot it (700ish).
The ergonomics of the stock I believe are much better on the Havoc imho, though that is subjective I acknowledge. The stock itself is MUCH more rigid on the Havoc, but I haven't handled the new FFT stock on the Ridgeline so that might be a closer race on the newer Ridgeline models.
While the Havoc action STARTED rougher than the Ridgeline, after a bit of use I think the Seekins is much smoother. I don't still have the Ridgeline, so in it's tough to do a direct comparison in all honesty.
Magazine length goes to the Havoc in terms of seating high BC bullets waaaay out there.
Same for twist rate. In 7mm Rem anyway, the Seekins is 1:8 as opposed to the Ridgeline's 1:9. Prolly a moot point in the 6.5 PRC I suppose.
Again, I'd happily shoot either one the rest of my life. I'd just be more confident doing it with a Seekins. Their customer service (while unlikely you'd ever need it) is beyond reproach from all accounts. The same cannot be said of Christensen Arms.
Just my two cents.
