Re: Anyone own a 7mm 300 Win Mag?

How dose Boss 300WM 215gr 3030fps .696 BC on elk stack up to the 7mm-300WM, knowing the 300WM dosn't need any special reamers or fire forming?

    I will always give the heavier bullet a thumbs up for elk no matter if the dia. is .284 or .308. This is why I am still shooting the 300 win. But out to 800 / 900 it might be hard to tell a difference. The difference will surely go to bullet placement. At 1000 plus I will give it to the 300 win and a 215.

    But things could easily change here. When we get to testing the new 195 Berger. A 7mm-300 with a 195 gr bullet at 3100 plus, and a BC of close to .800, well that just is not something any medium bore lover will want to look past.

    At 1000+ wouldn't a nice, fast 338 be the better choice?

    They duplicate the 7mm dakota in performance, only down side is you will require a 3.9" or 4" box mag from wyatts to seat the bullets out where you need them.

    Haven't had any issues with them yet on the 700 Rem or the Mark V actions. The 3rd one I did was with a DM.

    My 7-300wm is throated for 162 Amax's and it fits in a standard 3.68" Remington mag box with loaded rounds at 3.61" OAL. With 180's you'd need a 3.8" Wyatt mag box to seat the boattail junction at the bottom of the neck. The 162's, 168's, and 180's are all really close to 1000yds so I chose the easier path and used lighter bullets that fit in the factory mag box.

    They definitely don't need the long box. Have built several of the straight 7-300WM's and they fit well inside the normal 3.8" box and still have the performance.
