May I suggest using lighter boolits in
lighter weight rifles?
Powder coating and paper patching allow
the use of 45 ACP type boolits, since either
method will enable you to bring the diameter
of the boolit up to .460. There are lots of
threads on this site with the 'how to'.
While it's a short range proposition, a 200 gr
SWC, patched or coated is instant death to
Ohio ground hogs. And don't forget the
'collar button' boolit used by the troops of
the day for indoor practice.
Talk about fun -- these will touch your giggle button!
