Anyone got a 75 degree Kelbly yet?

I ordered 2 bolt bodies from Preferred Barrel Blanks that are in stock now and hopefully shipping tomorrow.

Been thinking about a Terminus for the shorter throw but if this 75 degree bolt is as good as I hope, then it’ll save me some $$$$.
 
Bolts arrived today and I did a quick fit and function check without actually swapping over all the internals and firing pin assembly.

I really like the shorter throw but it is noticeably less slick/smooth than the original bolt. Not sure if it’s a different coating or something (maybe one of the Kelblys can confirm?) but it’s not even close to how smooth the original bolt is. Much “stickier” when cycling the bolt.

I’ve got 2 Atlas Tacticals and they’re super slick and have been from day one. I do love these actions. I may hold off on swapping everything over until I hear about everyone else’s experience and decide if I’m gonna keep them.

Preffered was out of lh sa mag bolts so I'm curious to hear from others too

I just checked out mine today. However, the land of enchantment enacted a 7 day waiting period this year, so i can't bring it home until after the holiday.

The bolt lift feels good, cycling feels slick and about on par with my Impact 737 without a trigger in it, but I'll have to report back once I can bring it home.

The stickiness can be due to the fact that an original action with it's bolt has been hand lapped to each other. That is what makes a Kelbly so slick. The new bolt will take some cycling to wear in all the contact surfaces and smooth out. If it doesn't get as slick as your original, we would be more than happy to lap the bolt to the action for you and send it off for BlackNitride.

Thank you for choosing Kelbly's!

One thing we noticed in testing is the initial start to lifting the bolt is sharper (there isn't any cocking piece clearance at the bottom of the cocking ramp, this is because taking 15° of rotation out of the bolt limited additional clearance). In your hand it is noticeable the extra 2 pounds of lifting force, but when out shooting at steel or paper, the extra bolt lift is hardly noticeable. My brother and myself are die hard 90° guys and after running the new 75° in testing, we get the hype. It feels much quicker and the additional clearance to the scope is great to have!
 
Picked mine up today from the PBB sale with an extra 75* bolt. PBB swapped the guts over to the 75* for me. No trigger mounted yet, but bolt lift is around 7lb after cycling about 100 times and lubricating with the supplied grease. It definitely seems like something is wrong with it.

With the stripped 90* it’s basically nothing on bolt lift. I didn’t disassemble and swap the firing pin over to the 90, but realistically if it’s not cocking (no trigger and no dry firing) it shouldn’t add 7lb to the bolt lift unless I am missing something.

My factory r700 is about 2lb. Planning to call Kelbly tomorrow about it.
 
You might pull the firing pin assembly and shine a light into the bolt body interior. Mine was dry and showed some surface rust, all the way into the firing pin channel. I didn't notice it until after a couple of light primer strikes caused me to inspect that part (happened after post above). Lots of interior binding that went away after it was scrubbed, oiled, and polished and the threads re-greased.

If it’s not cocking would there really be any interior binding causing issues? It’s literally just a bare action with no trigger to engage the firing assembly
 
The lack of a trigger just means the firing pin is being cammed back and forth each time you pull the handle up or put it down. So the mating surfaces in the FP assembly, the cocking piece itself, the threads, and the pin in the channel are moving whether you have a trigger or barrel or anything else on.

Noted. Thanks

Disassembled, cleaned, regreased, no change
 
Might be worth putting the FP assembly back into the stripped 90 and see how it feels. Unless the ejector pin is portruding, or the extractor isn't seated in the notch properly, I just don't see how the body swap could add that much lift weight, aside from the stuff discussed above. The difference between my two is negligible now.

I spoke with Kelbly's today and it sounds like in their testing they averaged 5-6lb of bolt lift with the 75* throw and that after I get the trigger installed and a little bit of break in it should fall into that spec.

In all honesty I am a little bit disappointed. It is smooth and appears well made but I guess I wasn't anticipating a 6lb bolt lift. I understand that a 75* would require higher lifting force and I get that retrofitting a 90* to a 75* would cause an increase in bolt lift, but I am pretty used to my Tikka's which are very light on bolt lift. It will be an adjustment.
 
@TxLite you might just need more time breaking it in. I finally put mine together yesterday and it's about 15 - 20% heavier opening than my broken in Impact 737, but still much much lighter than my Tikka or AI. I did need to play with the sear engagement on my BnA trigger I went with on this build.

That's what it is sounding like. It has definitely improved since the first few tries, so we'll see how it does over time.

You are missing something, how the bolt gun works. Lifting the bolt cocks the firing pin, not the presence of a trigger. The trigger simply holds the cocked firing pin.
On a stripped bolt, you aren't fighting the firing pin spring and cocking piece isn't riding the bolt body. Any stripped bolt should feel like nothing.

Put the guts in *any bolt* and force will increase.
Pull the guts from *any bolt* and the force will drop to nothing. Compare them to each other with the bolt guts. Without the guts, it's a complete waste.

Yeah I think the part that slipped my mind was that there is no trigger there to keep the firing pin cocked, so I am effectively cocking it each throw.

Regardless, the pressure to cock the firing pin was higher than expected when compared to my other rifles, which vary from 54* to 90*.

I also acknowledge that it might also feel different after it's dropped into a stock instead of holding it when running the bolt.
 
@TxLite you really need to put a trigger on it and put it in a stock to get an accurate representation of how it feels. Otherwise there's too many variables at play affecting things.
Planning on it. Trigger arrived today but waiting on the stock. Don't want to dremel out my 700 chassis for the trigger hanger just for testing the Nanook.
 
I was cycling this action again the other night and have decided I'm very happy with where it's at. The extra scope clearance is nice. Now I'm just waiting for my action wrench to check the barrel torque before jumping into load development and I'll be ready post Xmas for the match season.
