My son just killed a whitetail with his 7mm-08 at 280 yards dropped it in its tracks his first deer, he's 12 years old. with factory remington premier accutip 140 grain ammo but I don't like factory ammo so I will load for his gun I think I can do better.Its a thompson encore with a 24 inch barrel.Some of these loads I will try.It sound like some of you have done well with this gun or caliber.I just think it will do well with a heavyer bullet because he was shooting a little less than 1/2 inch groups at 100yards
