KTW winchester rifle upgrade

[Mels]

Hi all,

 

So I have a KTW winchester rifle and would like to change the spring for a bit more power. Has anyone changed a spring in one of these? I can't seem to find any info about these.

 

I'm thinking I'm going to have to get a spring made up?

 

Thanks

First ask yourself WHY you want more power.

What are you expecting the extra power to do?

[Rogerborg]

Sorry, no idea, it doesn't seem to be a gun that people tinker much with.

 

Given the cost and the unknowns, I'd be very hesitant to put extra stress on the components, and would focus on the hop and barrel - again, unknowns.

 

Actually, I'm seeing it quoted at 117m/s with 0.2g, or 1.36J, which at most sites is going to get it treated as a sniper with a MED, for little if any extra range over a well sorted 1.14J gun.  I'd be tempted to drop it down to under 1.14J, to de-stress it and lose the MED.

 

I'd do that with a chrono to hand, using the intended weight of BBs, and (depending on how long it take to disassemble and reassemble) by cutting one coil and re-flattening, then repeat as necessary.

If I was going to push power limits on a KTW Winchester I'd be looking at Volante Airsoft's green gas conversion. It should allow a significant boost in power without putting extra stress on the gun.

Thanks guys, I think I'll end up going the gas route, power is around 275 on a .2 at the moment. Ideally I would like that to be on a .3. I'm looking into barrel and hop options at the moment. I'm hoping with a combination of all three I could squeeze a bit more range out of it. 

 

I'm under no illusions this would be cheap or even give significant gains. But its a nice project.

 

This is the exact model for anyone interested.

Thanks again.

Oh, that's disappointing (except to TM owners).  UK sellers to seem to reckon about that muzzle energy, while others sellers say 117m/s / 384fps on 0.2g.  Neither is really ideal for the UK.

 

Given how much that lovely walnut version already costs, it does make a reasonable argument for dropping more into it to make it all that it can be.  Officially jealous.

It is a lovely bit of kit, If only I could find some half decent Western revolvers to go with it.

 

Speaking of which have you seen the new TM single action army? Such a shame about its laughable power (90-100 fps on .2) as it actually has hop!

 

They do have an interesting design if you haven't already seen them

Wow, that's almost German levels of "because we can."

[EDcase]

So it just uses the kinetic energy of the hammer transferred mechanically (with the parts in the shell) to the BB?

Hmm, yeah not very efficient.

I can't stress this enough, the ASG Schofield is amazing. Shoots amazingly well despite having no hop-up. Very accurate.

You'll have to use these. ASG never made power down shells for the Schofield for some reason. These 3D printed shells are of very good quality and are very affordable!

I'm necroposting just to say putting 0.3s in a KTW Winchester will likely tear the hop rubber with the amount of adjustment needed. Keep them on 0.25s, if you tear the rubber there are no spares. 

Having had the volante and the original, just leave it original.

Can you elaborate on your thoughts on the Volante? I've previously only heard good things about it and have on order myself.
