I dont use them[in my Omega]for that reason if you dont have a good broadside shot the lack of penatration is a problem. My Omega shoots them very accurate but only with max loads so I dont use them when I E-mailed the co abot it the responce was that they are designed to be use with 70 to 90 gr but they say you can use the new Platinium up to 120 RS.
If you feel the need for that much powder try 250 gr 0r 300 gr Speer Gold Dots or one of the Shock Waves their are some others like the Nosler or Barns but they are priced high. Lee
