I picked up an Aspen Seneca on a whim at a pawn shop that had seen some use...but it held air and after testing it some I decided to try some heavy 22 Eunjin 28 grainers out of it and shot a .5" group with it at 50 yds., and have now found that it likes all the heavies i've fed it. Best 250 $ I spent in a long time.
