I've seen varying opinions on this and wanted to get ask a few more questions:

1. How well to the Numrich kits work? They also have some sort of metal loop in the picture. I assume that is NOT part of the assembly. Appears odd. See here: http://www.gunpartscorp.com/images/catalog/303560.jpg

2. Any disadvantage to leaving it cock on close? Especially for a DG rifle?

I currently have two actions - one with a standard cock on close and one that has been converted (appears it is the Numrich kit as the cocking piece does not look like the DT piece and the bolt was not modified). I had planned to use the one that had been converted to a occk-on-opening for a 35 Whelen and either use Cock-on close or convert to open for a 458 Win mag.

Thanks

Depends on what your familiar with especially in a DG rifle, chances are should you have other bolts, they cock on opening. Many years ago I converted to a cock on opening (from Brownells I think) simply because I would try to crank the bolt shut as soon as I felt resistance - if you get my drift. I think that ring is just holding the pin back for assembly reasons. FWIW --- John303.

On a Dg rifle you should be operating the rifle quickly from your shoulder. when you are doing this under stress you will never notice the cock on closing feature.

Got mine about 40yrs ago,still in 30/06 and works fine. No misfires.
The loop in the pic is a staple that hold back the cocking piece so you can screw it back into the bolt.Mine came tht way.

Thanks for all the replies - all questions answered! Thanks!

After operating cock on open actions for years I find my one cock on close to be a little akwards.

Maybe I need a litle bit more time on its bolt.

Personally I perfer cock on opening.

There's no game more "dangerous" than this one....




And for that the Enfield system seemed to work just fine!

I grew up on Enfield No4 rifles and can truly say that over five rounds rapid it was quicker than any and every Mauser!

It does seem you could work a cock on close a little easier from the shoulder since you are not lifting up to cock.

However, I've used my Ruger 375 H&H to hog hunt and I can crank it like a semi-auto without ever losing my scope picture and it's obviously cock on open.

I think it has something to do with what you are used to, and not having to under stress or emergency, rethink something that should be natural and second nature to you with out having to think about it. I've converted several just for the main reason as now they operate just like the rest of my rifles. There are advantages and disadvantages to both systems, depending on what you are used to using.

Watch the chap shooting the Enfield, about 20 seconds into the video.

Thanks for that KURTC...I'd seen it before, but like so many things forgotten where!

Here's waht the British Army eventually got:

In my opinion, the cock-on-close has one other advantage...which one should never need, particularly for DG, but it has it anyway.

That is, almost all the effort on opening the bolt is at first contributed to primary extraction...none of it is spent cocking the striker. That's only important if one has a sticking cartridge case and needs to get it out of there in a hurry.

But the tropics and facing DG is where you really can once in a great while use that advantage of the cock on closing action.

True a guy shouldn't be using ammo on DG if the casing is possibly going to be sticky to get out, but then there's lots of things we should all never do.......and sometimes we do them anyway.
