Out of all the MLers I have owned over the years, this little Impact has to have the tightest bore of them all. But I really think the munchkin will really like it. My granddaughter is already chomping at the bit to shoot it as well. Looks like the munchkins little niece is going to be her shooting buddy Just have to get loads developed that they can handle the recoil as well as not have to stand on the short starter and jump up and down on it to get the bullets started
