Greener GP Martini Action Question

[Ben Bowyang]

My first post here.

I have had a .32-40 rifle built on the 12G Greener GP split receiver takedown action.  It's currently having the stock work done.

I don't think it is an issue with my rifle, but I'm wondering what sort of pressures these actions can take?

Ben, the 32-40 cartridge as loaded for schutzen shooting usually takes a 200 grain plain base bullet and the powder charge is about 13.5 grains of 4227 or slightly less with 4759. At one time I believe winchester did offer a high velocity loading with the 165 grain jacketed bullet somewhere in the area of 1800 feet per second. That loading is no longer available of course.
if you want you can go to british militaria forums @yuku.com or the assra.com web sites for more information. There is a gentleman that goes by the handle on the british militaria site of Double D. He is way more qualified than me to give you a better answer. They live and breath british firearms there. Frank

Frank, thanks for your reply.

I will also go to those sites.

The split action GP is a shotgun action and should not be used beyond standard shotgun pressures.

That being said 45/70 are often built on the action.   It's not a strong action and the split action would NOT be my choice for a target gun.  I do have a friend who shoots a split action in 450 Musket No.2 in long range shooting competition and does quite well.

Help me out here, how does a "split action" differ from the Martini-Henry action?

[Frank46]

Joe, haven't seen one in the flesh but I think it has a cut on the bottom front of the receiver and a screw for removal of the barrel. Maybe Double D would come to the rescue with a picture to help you and me out. Frank

Big mistake in my post above I would NOT recommend the split action for rebarrelling in a rifle caliber or as a target gun..

Here is Greener actions.  They were used in sporting rifles, but primarily Greener made shotguns on them



This is a Martini Henry action.



They two different rifles and are not interchangeable in any way.

[coyotejoe]

I still don't understand what defines a "split action", what is split?  I've never encountered that term before.

[Double D]

If you saw it, you would know it.



The lowerpart of the receiver is split to facilitate take down, not conducive to strength or accuracy.

Thank you, that is the photo I needed to see.
