The FX Impact's Slug Power Kit comes with a pin probe. I like the idea and it does provide additional 10-15fps just between using it versus the stock Impact pellet probe, even after opening up the stock FX pellet probe's opening. But this thread is not about more power, but about ammo chambering consistency, which leads to accuracy.
When using the pin probe, every now and then(5-10% of the time), I get a "rough" chambering, which then leads to a flyer. If you want to shoot a good group with the pin probe, when you get a "tough and rough" chambering, shoot the shot away and ONLY shoot groups with a smooth chambering. With the stock FX Impact tube/cylinder probe, this almost never happens since the stock tube probe is able to seat the pellet evenly all the way all the time using the outer skirts.
So, am I the only one experiencing this with the pin probe? Or this is common knowledge and that all the great shot groups that were shot with pin probes are shot only with chamberings that are smooth? I am using 34gr JSB MK2 pellets, but with the shape of slugs, I can imagine this getting worse.
Just the idea of shooting a known "bad" chambering away bugs the hell out of me. What if one is hunting and loads a bad chambering round?
