Changing calibers in the Red Wolf!

I had a bet with myself you would do this video!

I heard Frank in the background. He was not happy that you didn't allow him to supervise ;-)

Very nice Tom!, straight forward vid. Excellent job, Thank you! I was thinking of adding a .177 hp barrel assembly? 

Thanks Tom. I had no idea about changing the probe. It’s interesting that Daystate doesn’t push this as a selling point for the gun. As you say it doesn’t look to be much more involved than changing the probe on the Impact. 

I had wondered whether the port in the gun itself may have been caliber specific. The port directly under the TP in the barrel? Be interesting to see with the higher power Safari if they make the TP larger in the barrel.

Having a lot of these guns I can confirm a few things;

1) The TP in the breech block is indeed different for the calibers and power levels availible, half a mm can make a huge difference in power output, I swapped a couple of mine about and observed this.

2) I understand the valve core "may" be different also in HP versions.

3) The other main issue is that each gun is set up individually in the factory on the programmer so they aren't all the same.

A .25 HP-Safari purchased would probably be the way forward, then the .22 HP version could be made from the .25, this way the TP would be the closest with regard to each other, buying a .30 cal gun and then expecting a .22 to work well would not be the case I think, perhaps a .30 to a .25 would though.

If you use a large breech TP in relation to the barrel TP and a low power program setting you can end up with an inconsistent gun.

If you have a HP and a non HP RW you will see that the screws that hold the barrel in are different on the two, the HP gun having bigger screws because the breech TP is drilled at the same time, then the barrel retaining holes are tapped afterwards.

This is great to know considering the cost of the rifle and not having to purchase another just to shoot a different caliber which was the appeal for myself towards an Impact. Maybe someday I’ll have to add a Red Wolf to the collection....

Hi Mark. Thanks for that information. I was thinking because these guns operate at such high pressure the transfer ports would have a bearing on the expansion rate of the air. 

When are we going to see some pictures of your Safari? 

That is great information Tom.Glad that well kept secret is out.

Thanks for sharing.

Awesome video Tom!

@Spray1mark: are the TP’s for the .25 versions (HP and non HP) different that you know of? I am asking as I got a second hand RW .25, that turned out to not be a HP version, but it was reprogrammed into one.(there was a sheet with the original settings and info showing that it was originally something like 18 fpe or so) I don’t kniw if it has a poly barrel either as I have never dissasembled it. (Serial # in the 1400’s)

Hi Martin, how odd, who reprogrammed it the dealer or the previous owner?

Did the sheet say it was always a .25 as I have no idea why a .25 18FPE would be sold?

Anyways as far as I am aware the .25 was always "automatically" classed as an HP version, only the .22 originally was availible with 35FPE & 50FPE HP versions.

The SAFARI of course is different to the old .25 HP, using a different board and barrel.

I dont know if the old .25 barrel was always poly for sure but I think so, I can find out.

Can you measure the TP in the breech of the gun & the barrel TP? to do the breech just remove the barrel and the rear barrel screw on the action, use the shank of a clean drill bit in the hole to confirm the size, the same with the barrel TP.

Let me know.

Just checked and the .25 has apparently always had a poly barrel fitted, but the SAFARI now comes with the updated type of ART poly barrel.

Hi Mark,

Thanks for your replies!

The gun was reprorgrammed by the previous owner, with the settings (and the programmer) he got from the dealer. (That’s what he told me anyway)

The info on the side of the box showed it to be a .25 from the factory, but as I got it from a Spaniard I guess it must have been for their local market with the energy restriction of something like 23 (or so) Joules...

I am away from home right now, but when I get back over the weekend I’ll measure the TP for sure! (And try to get a view of the rifling as well).

Okay great, that makes sense.

So I can change my .22 HP to .177 without any worries or problems? Does AOA have the parts that are needed readily available?

I wonder if you can do this on a Pulsar also ? 

So I measured the TP on the barrel of my .25 and it measures 4.35mm. The TP in the action is the same size, although it seems that the upper part is slightly larger.

I inspected the barrel rifling and I’m not sure, but it seems its a poly barrel. I tried to make some pictures of it, under certain lighting and viewing angles there is a clear hexagonal pattern visible on the breech or the muzzle end. When I tried to get a feel for the inside of the barrel with a wooden skewer, there was no resistance like when you have sharp edged lands and grooves.
