I dont know much about the shooting and or the ammo. 7mm is smaller round correct? im planning on putting a pretty decent scope so either way, accuracy is the same between the 300 and the 7mm? i know 300 packs a more punch? I dunno....
The major difference between 7mag and 300win mag and the ultras is about 14 - 20 more grains of powder. What it really comes down to is when the 7mag and 300win mag are max loaded to point of loosening up the primer pockets the ultra mags are not even stressing the cases.
I've done allot of chronographing of all kinds of rifles. Just like car racing. "When the green flag drops the BS stops!" I would not even own 7mag and 300win mag. I have a wild cat 7 STW and I shot out and sold my 30-378
7mm is .284 inches in dia. It is slightly cheaper to shoot 7mm. With a 175 gr spbt my STW went clear through a nice bull elk lengthwise. It was facing us slightly up hill 185 yards the bullet hit right at the chest and the neck and blew out its high right butt cheek. It knocked it down and did not even move. My 30-378 was set up for 220 - 240 grain bullets and any deer or elk it shot the bullets went right through them.
I am not a one gun person. But if I had the choice of a 7mm or a .30 it would get the nod towards a 7 ultra or 7STW I'm also pro .270 because loaded up correctly I killed a buffalo and the rounds will go through 1/2 inch of steel at 100 yards where your 7mag and 300 win just make impact craters with the heavier bullets
