What would be a better choice .284 win or the 7mm rem mag for 1000 yrd elk hunting and bench Shoting I've had a 7mm rem mag but I don't know nothing about the 284 and I'm considering it for a new build please help
Well at that speed, it is possible for sure. That is over 300fps over the book max though, but I am sure the 30" tube helps.
also gotta remember with the 284 that if you have .188 freebore set up for the 180bergers like the bench guys you can run the 162's way out before they touch the lands letting you add way more powder without the pressure. My last .284 (I am building another one this winder) I was running the 180 berger hybrids @ 3033FPS with no sticky bolt and no blown primers.
