Target System tuning/pimping

[Romeyo]

Hi folks!

I'm currently working on an savage target action what gonna be the heart of a tubegun project i'm running. I thought to to share that work since some of you might find that interesting

So here we go...
First thing was cutting off the bolt knob, filing the remained stub round to accept a thread and then turning a new bolt knob. The one I made turned out to be pretty massive somehow, but I kinda like it and since i've got the thread on the "bolt knob stub" I can turn any shape I like anytime i like...

Sorry for the bad pictures, mobile phone, you know... but you probably already guessed that..


The next steps will be a bolt lift kit. However I'm planning to use a small diameter ball thrust bearing instead of just one ball, but I will do the "conventional" 357mag case type system first to be able to tell you if using thrust ball bearings would improve characteristics any better.

I also plan on giving the accutrigger "real" 2 stage trigger chraracteristics by adding a new trigger lever that will replace the old one, but it still will have the accutrigger safety function. I somehow like the characteristics of 2 stage triggers more than 1 stage triggers, can't exactly tell why, it just feels more comfortable to me.

I also plan on cut trough the bottom of the action for mag feedind. I know some people might hate me for that, but I got several reasons for modifying a single shot action.
I plan on using either AICS or AW magazines I will cut the breach as tight as possible, perfectly fitting the mag to keep level of stiffness loss at a minimum.
However, I'm having a hard time to make a decision which one to use, AICS would be more compact overall, AW would be longer but also allow ~1/10" more OAL.
Whats your opinion? Both are center feed, however AICS mags are staggered. I don't care about mag width, in fact I think AICS mags would fit overall design better then the super thin AW mags, but 0,1" OAL gain might be a good reason for choosing AW mags... ???

"Been there...done that". There isn't any advantage using a thrust bearing over the singe ball. The purpose of the ball in the "lift kit" is to reduce the contact area between the bolt assemble screw and cocking piece sleeve resulting in less friction between the two operating the bolt.
