jerrymontgomerybolt stop problem on mod 70
I took apart my 300 H&H for re-barreling, and removed the trigger and bolt stop for shipping. After putting it back together the bolt stop will not stop the bolt altho it moves freely.
Can't figure this one out! My long-time hunting buddy says I'm too old to be doing things like this.
Any ideas?

You forgot the spring or didn't connect it correctly.

jerrymontgomeryNo, I didn't forget the spring, and I don't see how it could go in incorrectly.

jerrymontgomeryThe actual bolt stop is a sheet metal strip, spring loaded, that is pinned in the receiver. The part (a separate piece) that you depress to slide the bolt out hangs on the trigger pin, but I can't see a connection between them altho there must be one.
When I removed the trigger (and the bolt stop lever) prior to sending it off for re-barreling I was very careful to put the parts in a small bowl and put the bowl in the top of one of my safes. I can't imagine how anything got lost. The inner, actual boat stop was left in the action. If there IS a missing connector part, I can't see where it would be attached to the action or to either of the sheet metal parts.
I'm taking this rifle to Africa in three weeks. Maybe.

jerrymontgomeryAfter further inspection , the inner spring-loaded part that I thought was the stop is not a stop; it simply rides in a groove in the bolt and is maybe a stabilizer.
So- the actual stop needs a spring. I have lots of springs, but where does it go? I can't see a receiver hole in the slot in the receiver nor on the lever, and I can't see any wear in the bluing which would be there after many years of use.

The spring loaded part is the ejector blade. The bolt stop protrudes up through the left ise of the action and is the same piece as the external button you push to remove the bolt

jerrymontgomeryOf course! The ejector- I should have known that.
So where does the spring go on the bolt stop? I understand how it works; lacking a spring I can work it manually, but where does the spring go? Possibly I can simply put it in the slot and it will find it's own spot. I'll try that.
Thanks.

You can see the ends of the spring at the arrows. There's only one way to get it together so it works.
That appears to be a post 64 action. Pre 64 has a hole drilled in the back of the L side receiver that a spring and plunger goes into. You did not specify if pre or post 64 action. Hope this helps.

That's a good catch - I only have newer ones so that's where my mind went. He must have the plunger style.

jerrymontgomeryBaxter came up with the solution, about the hole in the receiver that the spring/plunger fits in.
This is a pre-64, but a late one (the earlier ones had a larger spring/plunger than my '54). I have a couple of suppliers looking for the springer and plunger. At least, my confusion is over, at least regarding this matter!
Thanks for your help; without it I'd still be scratching my head.

Looks like pre64win.com has the parts. Wisners has the spring only. Spiff it up with one of Jim's checkered bolt stops levers, very nice.

J WisnerI just made some of the bolt stop plungers # 3170, early this week
Thought I had updated our website, but will check

squeezenhopeI wonder how many times someone has had to chase that plunger???
To Mr. Wisner, thanks for the Pre 64 parts you make!

Jim KobeThe pix show a post 64 and mention a pre 64. What is it? They have two different spring mechanisms!
