Picked one up today after reading about it. My plan is to kill one bird with it and then take a pic with the gun and retire it until my grandson is ready to hunt it (he is 18 months). A few other young'uns in the family ahead of him that may use it.
The place I bought it (local gun shop) had the Federal TSS 9s. After sighting it in (came with optic) with some game loads in close, I shot it at 30 and 40. Did not take pics. The 30 was pretty good and the 40 would have killed the bird, but not the nice even pattern I am looking for in a kid's gun. I did not count the 10, but I would guess about 100 or so at 40.
My plan is to polish the barrel and then give the stock choke and the Federals one more try. If I am not impressed, I think I am going to try the Nitro ammo and choke. Saw one on here that had 9x10 that looked most impressive. I am not chasing numbers, just want a nice even pattern in the 10 with no holes and probably the 130s as a good starting point.
