I picked up my new Ridgeline from my ffl buddy late last week. I had just enough time to take it home, tinker with it a bit, mount the scope, and then get to the range for a rough sight in before taking it hunting Saturday.
Even so, with what little time Ive spent with it, Im beginning to feel that this is a great rifle even for the high price.

First off, specs on the rig.

I ended up buying the stainless and black Ridgeline, in .280AI with a 26" barrel. Id have preferred the bronze and green, as a buddy down the road has the stainless and black in .300WM.
The rifle came with the radial brake mounted, and my Initial sight in was done with it in place. It also rang my ears right thru the ear plugs so quickly go yanked off when i got home.

The scope I mounted on this was a Zeiss Conquest HD5 3-15x42 z800 reticle. I chose this particular scope because of the relatively low weight, magnification range, and cost were all good, to very good, as compared to other brands of similar models.
I have to say that im quite happy with the scope, and i think its an excellent option for this combo.

The scopes mounted in a set of Talley mediums.
I was unsure if the lows would work with the larger 42mm objective, and the larger barrel diameter the Ridgeline sports, but it looks like i could have gotten away with it. I may go ahead and change them as my head does float a bit.

I think the parts list, and workmanship make this rifle a very good deal in the 1700-1800 dollar range. If theres one knock i have on the rifle, its that their spot bedding job is exactly that. One spot of bedding compound. This is actually probably plenty with as well fitted the stock and pillars were on my rifle, but i went ahead and gouged it out and skim bedded the whole thing.

In the field this rifle carries like a regular weight hunting rifle, its balance actually makes it feel lighter than the 8.5lbs it weights. The weight and distribution is also such that it hangs extremely well for off hand shooting. So much so that I chose not to run the bipod that @troy fairweather so graciously sent me, on this hunt as most of my shooting would be quick, off hand. I did zero the rifle with the bipod and found it very easy to shoot set up like that (i had to epoxy bed the pod to the rifle since the thin forend dosent play well with the pods relatively wide contact plate.

The only shooting ive done with it so far is to zero quickly with federal .280 140fusion rounds, test 3 or 4 rounds of 168 ABLRS over 63 grains of retumbo in hornady .280ai brass, one shot while hunting, then another 7 at the range on the way home. Thus my opinion is NOT fully formed as to how well this rifle will shoot, but i must say its promising
The 140 fusions clocked 2960-3010ish during fire forming, and accuracy was well within Christensens MOA guarantee.
My Retumbo loads ran a couple hundred fps slower than i expected (2770-2800), and this Isnt the first time Ive noticed this. I opened this particular jug back in 2010, and am just hitting the end of it now. Which could be the cause.

Anyway PICTURES!
ohh...need my phone for those...ill get them uploaded

powders to try!

Last targets shot with the federal fusion after hunting Sunday.
Shot off a stable bench, but from a loose sandbag front rest, and wadded paper towel rear rest.

corrected 3 clicks right and used 300yd hash mark at 15x for first shot (low right)
changed to 12x and rest for 3rnd group above that one.

admittedly this isn't horribly impressive for guys that can really shoot, but it's about as well as I can do on my best day. This is also cheap factory 280 ammo, shot about as fast as I could shoot and load. (we were already about 2hours late heading home)

I'll actually go measure the groups but the 200yd is about 1" and the 300 about 2" (I think the red circle is 2" anyway.

You greatly offended me. I speed read through your post to see no pics...
8.5 lbs is the perfect weight for a hunting rifle in my opinion. Just heavy enough to swing smoothly.
By the way I had great luck with H1000 and imr4831 in 280AI.
pictures are up, had to figure out where my daughter had hid my phone this time lol.

I'm gonna bully my buddy into giving me some h1k to try, it seems like a popular one.
Im also working upoads for my 6.5s so the slow to superslows are getting a work out this round.
 
ya good looking gun, i like you don't have to much scope, that power is just right. and when you shoot this barrel out you can ream it to 7rm, i think dad still has his 7stw reamer.

Very nice. I really did that rifle and I'm a Maple or Walnut type of guy.
I have a 15 month old that my brother calls baby zoom zoom. He zooms around stealing phones and remotes. If you have patience, he brings them back. If not, you will destroy the house searching.

im not positive you can ream these carbon tubes out to a much larger case, but it's a good idea.

I really like blued steel and wood myself, but this thing really looks exactly like what it is, and that's pretty cool too.
My daughter's pretty good about not hiding stuff too badly, but it was nap time and it went into the couch pretty deep lol.

Nice. If I ever buy another long action, it will be a .280AI.
I'm pretty stoked with this one. so much so I'm contemplating buying a cheap long action to build a more traditional rifle from to see if I still like it as much as I do the Ridgeline.
Recoil is noticeably less than an 06, and factory ammo is matching the hot handloads im doing for the .270 I just gave to a friend of mine.

I need to finish this .375 raptor build that fell in my lap first before thqt experiment tho.
 
Those results do look very promising and good shooting! That's a really nice looking and functional setup. It's good to see a rifle/scope/ammo combination that's well thought out and well executed. I have that same scope and four of the older Zeiss Conquest MC models. Zeiss with the RZ reticles is my go to manufacture/model for hunting optics. Really looking forward to following along with your load development.

Is that the weight all in i.e. rifle/scope/rings?

ya thats fully loaded.
 
ya i wonder how much meat is left in the shank on there barrels. when i go to my dads i will see what his 280ai loads were.
thanks I'm curious what everyone else ended up using.

The LR guys are generally running the slows to superslows, but they mostly have slightly longer tubes than I do. Factory data is all 24" and the medium slows look better there.
probably time to buy another copy of quickloads.

Awesome …. will make for a great sheep/goat rifle for the Big Island I'm sure.

Yeah I wanted something to use as a general hunting gun, as I was mostly using my .375 for that. This Ridgeline seems like it's gonna fit the bill really well.
along with my.243, 6.5s, and .375s I think I got pretty much everything covered at this point.

Nice. You'll like 280AI. Nosler data, they use 26" for 280AI. Mine on Rem action, 27" Lilja barrel, McMillan stock and Nosler brass. I'm using IMR-7828ssc,162gr ELD-X,Fed 215m. I've also shot 160gr AB,178gr ABLR,180gr Berger, and 168gr Berger. I used H-4831sc with Berger 180gr.


I've got Forbes model 24 and that has Krieger @ 25.6" chamber for wildcat 280AI and I fire form brass for that.

those sound like sweet rigs!

I didn't notice nosler listed a 26" barrel for everything besides the 168s (which are what I have on hand), they change to a 24" just for those.
I've got a spread of 7mm bullets 120vmax included, which might be fun.

what kinda velocity are you seeing with 7828ssc? I only have the regular, but I figure performance should be pretty close.
 
my handloads cartridge conversion manual lists 58gr of 4350 under a 175gr. 2850 fps data from ackley.
58gr of any 4350 sounds like a really stiff load behind a 175, nosler and hodgdon are topping out in the low 50s.
If I remember correctly, that's the charge of imr4350 I used in my 7mag behind a 175Sgk.

ya i sometime think ackley used a press to pack powder in no some loads. his load for the 7x57ai is like 55+ with a 140 or 150 . i know 52gr is just at the neck on my 7x57ai.thats imr 4350. i do 58.5 imr 4350 with my 7wsm with a 150gr it's a mild load just to compare.
