This always turns into a 30 cal vs 7mm thread. Ive started them and researched it till I couldn't retain any more information. Ive always been a 30 cal guy and still hunt with them, but my long range gun is a 7mm Mag. Based on the criteria that I established, ( 1000 lbs of energy on impact and still supersonic, with no muzzle brake
) the opinions I got here, and the research that I did, led me to the 7mm choice hands down.
** Im not trashing the 30 cal here guys, or arguing the effectiveness of putting meat in the freezer, just my train of thought on my recent purchase.
Here's some of my reasoning:
1. Recoil -- to push a 30 cal bullet at the initial velocity needed to meet my criteria, I feel would have produced a rifle that was not "fun" to shoot, and therefore my level of proficiency would suffer due to not shooting as much. I dont want to have to use hearing pro in the field, so the muzzlebrake was out for me.
Energy/ velocity -- Run the numbers on a .284 168 Berger out of the 7 mag, and will retain more energy and velocity than the .308 180 Berger from a 300 win. ( I know the 300 Ultra and 30-378 will get them there, but remember my muzzle brake criteria?)
I guess the deciding question is how long of a shot are you wanting to take? If its past 700, i say go with the 7, otherwise, the 30 cal has served me well thus far out to 500.
Goodluck and let us know what you decide.
