Hi Mustard, welcome to the forum and to air rifle shooting.
In answer to your question we were shooting benchrest at our club today and the targets were multiple 4cm targets on a sheet approx A4 in size and they were set out at 50m. Being a tad too windy we were finding it was necessary. to aim off to the right by approx 2" but most of us were able to put in scores of about 120+ out of a possible 250. On a good day we would normally score about 180-190.
It was too windy for our other competition which is a 7" target with a 1" bull at 100yds. on other days we have scored about 110 ex 120. None of us are what you would call exceptional shots and we shoot the competitions for the fun we get.
Hopefully this should show you that anything up to 100yds is possible with a pcp or springer with good results depending on you rather than the equipment.I shoot both Air Arms S400's and Air Arms TX200 and achieve similar results with both at 100yds.
There is so much info available on this and other forums to help you.
Good shooting!
Jim
