Take the leaver off, I used a large leather mallet, and give it a Whack! theres been a fellow on here that did that and it did break the leaver, but hes bigger than the average fellow is! its a trial and error Process!

So I’m trying to keep up here. Roy, are you saying the bolt moves up into a wedge and not square shaped recepticel? And Plab are you saying that tightening the arch of the lever will only result in lowering the height of travel the bolt can make?

I'll not comment anymore until I get home late tonight and study on my bare action a bit. I suspect everybody is right in their own way.

We're just talking it thru, and I'm with you, I need to study this more. This is how it gets done guys. Thank you for the civility.

that's correct but it's very slight. a 99 shoots better with a tight lever. because your taking some of the movement out that the lever allows the bolt to move. who knows how it gets to the loose lever ? wear and tear I would assume . and yes the rear of the bolt and the mating surface are angled .. I think I read somewhere it was 6 degrees but I'm not sure .

Ok, so now you have the knowledge to tighten your lever drop. Do it and see where you are at. Likely you're done and happy.

Take the rest of the comments with a grain of salt.
As gnoahhh states, others may all be correct to some degree, but may not have anything to do with your rifle.

Anyhoo,... a picture is worth a thousand words. Here's the parts involved.

Interesting and thanks. So another consequence of tightening the lever arch is a slightly loosened lock-up. Personally, I think some 99s just got out of the factory that way. My fix would be to add some metal to the friction end of the lever arch and refit it. But I’m not a welder and don’t know if the heat could be controlled that good. Or I guess you also could play around with other levers until you got one that gave you good lock up.

I read where Colburn nixed the 3006 because the 4 degree pitch on the rear would not contain the pressures. I think I read that .

HI Everyone
I am new to this forum.
I know this is an old thread, but found it very interesting.

I recently bought a straight grip 303 savage 1899 at auction. It had this drooping lever issue to the extreme (I did not know this before I bought it). When the trigger was pulled the lever would drop open about an inch. The firing pin tension was the only thing holding the bolt in position until it fired. Needless to say, I will not be firing it in this condition. I knew the stocks were garbage and so it is now a complete redo project. The condition of the rifle led me to this discussion.

Not counting my time I expect the total rebuild cost to be about $400 CAD or about $300 USD (obviously nothing for my time ). I know it does not sound like the best investment, but when it is done I hope to have a unique custom firearm with one of the best lever actions around. I have a fairly nice 99 in 300 savage so this was meant to be a project. I will admit it will be a bigger one than originally anticipated.

I have ordered a new lever from Numrich (Gun Parts).

I will be re-barreling it to 30-30 win (original barrel is a sewer pipe) using a Green mountain 7.62x51 (1:11.25 twist) barrel. I am toying with making the barrel an octagon about 20".

I have ordered a stock blank from Gunstocks INC. (who are closing down) and will whittle up a new forend.

However returning to the lever issue I would like to recap what has been written above based on my studying the lever issue. I am not trying to say anyone is wrong (because this would not be true). I am just collating it and hope to get confirmation from those more familiar or possibly introduce a point not fully covered.

The 3 critical points on the lever in my opinion are the following

1/ The lever pivot pin. If this is excessively loose it may affect the performance of the next two points. but is likely less critical to function than #2 or #3.
A loose pivot pin will allow the lever to move forward reducing the contact tension with the locking surface (which I will call the frame lug). The lever is held in tension or lockup with the tension between the frame lug and the pivot pin. When the hammer method of tightening the "C" is used it may just be correcting for some of this play in the lever pin as well as wear on the lever end and frame lug.

2/ The end of the lever which contacts the frame lug. In some cases can be corrected by closing the C. If the wear on either the lever locking surface, or a loose pin, or wear on the frame lug, is minimal. If there is minimal wear on the surfaces mentioned then percussive adjustment as mentioned will "likely" not affect my point #3.

3/ The cam follower and race. The cam follower (non rotating) is the round locking protrusion on the left side of the lever about 1" from the end of the lever. This protrusion/cam follower engages the angled cam race in the bolt. The race in the bolt is angled to allow the follower to drop the bolt and guide it backward through the lever stroke. At the last moment of closing, the follower will locate on the forward point of the cam race, which is a small horizontal flat. When the lever is closed, the left side follower will locate on the flat area and hold a small amount of tension upward against the flat which is caused by the frame lug/lever interaction.
Looking at it in another way, the force of the closed bolt against the receiver, is transmitted down through cam race flat to the lever, and this forces against the frame lug to lock the bolt in the closed position. It is a delicate balance. Too tight and bolt will be hard to lock but harder to unlock once the fired case is pushing back against the bolt. If the lock up is perfect the lever will close and lock the lever in place on the frame lug and the cam will hold the bolt in the full upward position with a little bit of tension. When fired the bolt will be pushed back against the frame. The angle at the back of the bolt will start to apply pressure downward. At this time it is imperative that the cam follower nub is resting against the flat at the bottom of the race or you will have the issue I have of unlocking. Proper interaction will position the lever to absorb the downward force and will allow only minimal (if any) movement. An excessive clearance between the cam follower and the flat portion of the race will create a variable headspace situation upon firing. As the firing pin hits the primer, the expanding case will push back and any movement will allow the case to stretch back changing the headspace.

I believe the correct interaction of these areas is vital to maintaining a safe firearm and possibly increasing accuracy. So If you tighten the C to improve lock up watch the clearance or amount of vertical movement of the bolt. You will absolutely need to be sure that the cam is still interacting with the horizontal flat area. One method to check that it still properly locked is to us a soft face mallet to tap downward on the bolt to mimic a shell firing. If there is a small vertical movement of the bolt but no unlocking you are probably safe as long as the lever remains solidly locked. Keep in mind that if you can push the bolt vertically up or down this will translate into a variable headspace situation which may affect accuracy.

Sorry for the long winded comment.
Let me know if that is the way you see it.

Two other comments. Yes welding the contact locations (cam follower and end of lever) and machining back down will likely work but you may want to re case harden after.

The other comment about 30-06 and pressure does not make sense, since the 308 works at the same pressure, it is most likely, that the action, is not long enough for this cartridge and similar ones.
