Hello everyone, new to the forum. I have a tikka t3 300 win mag that I am currently shooting. Have about 400-500 bullets through it. i was thinking about trying out a new barrel but I am not component in this area on the capabilities of this action and rifle model. I was thinking about changing the rifle into a wildcat 300wm-7mm which means a 300 case pushing a 7mm bullet. Correct? Am I a fool for attempting this or what. Currently running 2880/2890 FPS at the muzzle with 210gr VLD on 67 grains of 4451 on the factory barrel on my 300 win mag. I still would like to keep the ballistics up enough that 600 plus yard shots are manageable on a elk or mulie. To make a long story short, am I wasting my time and money for what I already have. I want a long range gun. But think I mah already have it.
