300 win mag vs 7mm rem mag for deer. I mean the only difference is the nomenclature. Have been using this load since i hunt somewhat close to houses. Velocity is typically 100 fps faster than the 270 win which is not bad but the 7mm rm uses lots more power to get there. Which is superior in the 7mm vs 30 caliber argument.
Shoots with jaw dropping velocity power precision and bone shattering energy on impact literally. Launched at maximum velocities for each. In the 7mm vs 30 caliber debate which reigns supreme. Three shooters that joined me at the rifle range with a 308 a 762 and a 300 win.
If youre going to burn lots of powder and make lots of noise you might as well do it up right. 110gr sp 580 gr. But according to my handloaders manual of cartridge conversion the 7mm mashubrn super is a 300 win mag necked to 7mmcase length samesame shoulder angle is samesame. A reader recently requested a ballistic comparison between same weight bullets in a 300 win.
I have used both for deerit depends on what you plan on shooting with the rifleif you plan to do a good share of elk hunting i would suggest the 7mm magif deer sized animals are the primary target then either will doi am a bit partial to the 264 myself but thats my preferencei killed a fair amount of the local deer with a 7 mm mag shooting 154 gr hornadys at about 2800 fpsmy dad on the. 3228 win lr. Load data for the 270 winchester. In the real world theres not enough difference to matter much.
But thats just me. With either you can easily exceed that magic number of 2850 fps and with the right bulletload combo head north of 3200fps for varmint hunting where flat shooting makes a big difference. Never had any interest in the 7 rem mag at all. In looking at the reloading data the 7mm is pretty anemic for a mag.
300 win hands down imo. One veteran gunwriter weighs in on the subject. It is the second or third most popular hunting caliber for lots of reasons including moderate recoil. Pardon me for pointing this out.
