The Terminus Zeus bolt lift is comparable to any two lug action on the market.

I got that email too. I already have a Gen 1.0 Nucleus. It's been a great action. I was thinking of something else This time, not that I need another rifle. LOL

One of these days I'll try one! I really like the vector I messed with ..

Someone ask about Bordin bumps. It's where the bolt body has raised up sections so when the bolt is in battery there is no verticle play in the bolt body. This helps keep both lugs touching when cocked. If you have any slop in the bolt in the rear of the receiver when cocked the seat engagement will lift the rear of the bolt up to the top of receiver. This will put more pressure on the lower lug and lift the top lug off the abutment. When the bolt is lifted and cycling the action the bumps are in the raceway so you have clearence for smooth cycling. Hope this helps.

Joel,
What weight firing pin spring does it have? I have never been able to handle a Terminus action.

No problem. I use Bordin actions whenever I can. They are works of art and precision. I build Bordin bumps into my remingtons bolts when I sleeve them. Learned this from Greg Tannel.

It is to add the bumps to take the play out when in battery.

Do not look at a steeper cocking cam as a bad thing. A shallow cam opens nice, but the down side is cock on close or short pin fall. Personally I like a timed action with no cock on close and proper firing pin fall for good ignition. Dont get caught up in how an action feels. Anyone can make one open easy. There is a reason the guys that know better dont do it.

I live 40 miles from Greg Tannel. Good guy with lots of skill and knowledge. I've talked to him for 45 min-hour at his shop a few times. From what I understand he makes the rollertip cocking pieces for Curtis.. I assume terminus now also but I may be wrong. He also was and maybe still is , doing all of Bighorn's fp springs and if I'm not mistaken the FP itself also. Floating bolt head also takes care of this issue. No matter how square the action is. The bolt will always tip up when cocked and closed. Only way to fix it is Borden bumps. Or super tight riceway( not good for dirt and grit). Or floating bolt head. I just personally like the floating option. Then my one action can be a 204 or a 6.5saum or anything that'll fit a SA. Shoot my 204 barrel out then if I want a 6.5 creed. Put my new bolt face on and away I go.

I would never say no matter how square the action is. A floating head will always have both lugs touching but if it's not square it will still be crooked. Still needs to have equal lug abutments and a square face to the back of the lugs. But it can have a looser bolt fit.

Nobody makes a Kelbly action work better than Alex. He makes them the way they should come from Kelblys.

Yes if the lug abutments aren't square to the action the bolt head will touch on both sides but be out of parallel with the rest of the action. I should have clarified it a little better
