Has anyone ran slugs in the .25 cal. 250z yet? If you have what size did you have luck with? Thanks.
Barra Slugs in the 250z

Good morning everyone… thought I’d share a little early morning action using @JFranco fantastic slugs. If you haven’t tried them yet you need to. Best slugs I’ve shot out of my Barra.
This is the same rabbit. I’m zero’d to 75y so you’ll notice the huge hold under on the first shot which the rabbit manages to totally matrix his way out of…. Second shot is 85 yards and if you have the sound up you can clearly hear the slug hitting him…

@Cantona256 How did you open up the transfer port on your 250z? From what I could see the only way to access it is thru a threaded hole in the bottom of the block and it’s already as large as possible. Unless i would rethread the hole for a larger bolt.

Yeah the little air channel defo needs to be opened up too which I haven’t done. I did the transfer port on the valve assembly and the exhaust port in the intake sleeve… since they a matched it would stand to reason that the Venturi effect causes the air to accelerate through there and the pressure drops subsequently.. not sure what happens when it hits the the 4.4mm exhaust port. All I know it’s that the gun feels a lot better this way and I’m getting 65fpe while still getting about 25 a fill(as long as it’s warm outside haha)

It’s definitely not a full port and polish but it’s been really effective for creating a “medium tune.” Should have the plenum mod installed in the next month or so which will make my current numbers super easy to achieve?
If you want a plenum I have the guy’s email.

So I did some asking around and the answer to the question is to drill the block out to just a hair below the size of the threads so you don’t have to rethread. I probably won’t do that yet as I’m already really loving how it shoots and I wanna see how the plenum does. Plus he’s working on some poppet Valves and dual ports for more power increases as well.
