I AM USING A WINCHESTER PLATNUM TIP BULLET.IT IS A 260GR PTHP. I LIVE IN OHIO.I WILL BE SHOOTING FROM 50-100 YARDS.I HAVE TRIED 150GR - 100GR.POWER CHARGE.AT 50 YARDS I AM ON.ALMOST HIT THE SAME HOLE.BUT AT 100 YARDS I AM AROUND A 3 INCH GROUP.
That Winchester bullet is an excellent bullet. I beleive you will really like how it performs for you.
If I could I would make this suggestion to you, as soon as you are comfortable shooting your rifle make the switch to loose powder it is far less exspensive and usually you will be able to taylor your loads to you gun and your bullet. I would also suggest T7-2f powder as it is cleaner and less corrosive. I shoot the same weightbullets for deer and I am shooting 100/110 grains of loose T7 - this is a very good load for me. I normally shoot a Nosler Partiton 260 grain HP which is very simular to your Winchester, but the cost of these bullets has gone sky high so I am making the switch to a Speer Gold Dot - 250 grain Bonded bullet. Lot less money and a proven performer + I can afford to shoot it at paper.
In my book a 3" group @ a 100 with open sights is right where you want to be... and the more you shoot the tighter it will get.
