Nosler RDF 22 Caliber .224 77 GR Hollow Point Boat Tail HPBT 500 Box. 224 77 GR Hollow Point Boat Tail (HPBT) 500 Box - Bullets with a high Ballistic Coefficient (BC) will generally shoot flater groups than those with a lower BC even at the same distance. This is due to the boat tail reducing the drag of the bullet as it travels which results in the lowest wind drift. However since the wind causing factor is so low at .22 caliber care must be taken to avoid undue wind drift which can wreak havoc on a low BC bullet. To assuage drag the Nosler RDF 22 Caliber .224 77 grain HPBT 500 Box features an extremely slim meplat. Because the Meplat is so small there is no need to trim or point the Nosler RDF 22 Caliber .224 77 GR Hollow Point Boat Tail (HPBT) 500 Box requires absolutely no bullet prep or trimming and is a viable option for target shooting as well as hunting.
