Smilin' here....they built the .30 Sneezer....
I don't have any target pics handy for the .30-30 but it is a sub MOA shooter. My other barrel has a .22 short match chamber. Target below followed a serious barrel cleaning in numerical sequence using the red dot sight. CCI CB shorts zeroed for pigs. It runs 1/2" for 5 at 50 yards with the CB's and CCI HVHP shorts. That barrel has slain over 100 wild hogs.
The Sneezer at 50 yards with a red dot sight;
And these bullets; 30:1 183 grains.
I'm considering the purchase of a .25-20 Win barrel just for chitts'n grins. I suspect I might wind up with a Hornet barrel at some point as well.
