Does anyone know the diameter of the Pro Target barrel?
Thanks

Hi and welcome to the forum.
What parts did you need to convert from one to the other?

Same here, check the forums every 2 or 3 days, comment if I can help.

Here you go.

There are some brass ad-ons on eBay if you have no luck here.

Can anyone with a pro target check something for me please.
When the rifle is loaded, how tight is the breech block on the stub of the barrel?
Is there any play forwards or backwards?

Can't remember the make of my pull through but it is a bit stiff, still flexible though.
I have pulled through the barrel of my 500 a few times without removing the stripper.
Most of the time I only fire 3 felts through if the accuracy goes.

Cheers for the replies.

Cheers Tony.

I'm going to experiment. I will try the pot length 1st - longer and shorter, to see what difference it makes.
I have not measured the length currently, just followed Ray's guide.

The sweet spot on my 177 s200 is from 155 to 110. It goes from 770 to 790 and back down. Will just increasing the hammer then using the venturi allow me to extend it and make it flatter? I would like it to go from 165 and have a less fps variance.
Or do I need to increase the pot length?
