I am sighting in my 1973 T/C .50.
I notice that, as I shoot T/C maxi hunters (320 grain) that I have great difficulty hitting the target after shooting several rounds.
It would seem so far that I can get good groups with 80 grains of Pyrodex RS but am conerned that that load won't be good enough on elk. When I go up to 90 grains and 100grains my rounds won't group.
The Pyrodex is about 3 years old and has been kept in a cool dry spot the whole time.
Would appreciate some suggestions.
Also, how often should I clean the bore at the range?
Should I shoot a few rounds and let the barrel cool considerably before shooting again.
Thanks in advance.
