Stetson

I blasted them all into the same target at 50 yards without much regard for making a tight group... It's just a big hole so there's no pulling out the 30 grain load.

This is a "by inches" rifle and I'd suspect (later to test) it'll shoot to 2" or so at 100 yards as it did with the 27 grain load. The receiver peep hole is ~.120" and I have a larger ~.180 for dark wood hunting.
