Im thinking of buying a new barrel for one of my savage rifles. I would like it to be a target first then hunting second rifle. I would like it in the 6mm/243 caliber. Right now i am leaning towart a McGowan 30" in 243 Ackley Improved. Are there any other calibers out there that i should consider. I am wanting to shoot the heavy 115grain bullets. I already have a 6BR and 6.5x284 so those calibers are out. I have read that the 243AI will almost match the 6.5x284 when shooting the heavy 115g bullets. Anyone own the 243AI and have any pros or cons to it. Thanks for any and all help you can give.
