Ok, I have narrowed my choice down to the 7mm RUM and the 300 RUM. I am leaning towards the 7 RUM, I have always been a fan of the 7mm's. I know you shoot as heavy of bullets, but was wondering if with better ballistic coeiffent, if it is still the better choice. Do you think the 7RUM is a dying cartridge and the 300RUM is better. Any help on this would be greatly apppreciated, just getting into long range hunting.
