Got to agree with "shenners" on his choice of scope, I have the same Simmon's WTC on my HW100 and it dose,nt miss at thing form 10>45 yards, as for the pellet's I use the same pellet Hull cartridge set's the HWs up with at the factory...H&N FTT and let me tell you they are the biz in my rifle..... ( sorry the scope's are covered up with a protector but they are the WTC 3.5-10x50 ).
Good luck with whatever you choose....regards
