7mm Rem Mag vs. 300Win Mag

[model 70]

Long range DEER hunting. Which out perfomrs the other and why?

[rem 700]

7mm Remington magnum. Why? It's outstanding long range accuracy and flat trajectory making range estimation just slightly less important than that of the 300 magnum, and the tighter groups. The sizzling speeds sustained at long ranges, and the energy that is close to that of the 300. Less meat damage: the 28 caliber bullet won't cause as much damage as the big heavy 300 magnum bullets more often used for AT LEAST elk sized game GENERALLY, making the bullet selection for proper deer bullets minimal.

Sp providing the hunter can do his part, what are the outter limits of the 7mm Rem Mag? Say....shooting 150gr. slugs?

[rem 700]

Oh, I would trust a 7mm mag @ 600 yards definitely, even more depending on condition of wind and angle of shot, and the expertise of the marksman. What bullet type in 150 grains would you intend upon shooting in a 7mm?

[Evan03]

at 500 and beyond on lar game id use amax or nolser balistic tip, so that there was atleast some kind of expsnsion.

[model 70]

Yes, 150gr. Sierra BTSP's or Ballistic Tips would be my choice.

Take a close look at the long range ballistics of a well shaped .30 cal. 200 grain bullet from a .300 mag.

My .300 Win will start them at 2960 fps. With that muzzle velocity they become a very serious long range threat. More of everything, actually, than you can expect from the 150 grain 7mm in my opinion.

[rem 700]

Be careful with 150 grain BTSP's. They're not a long range round: they make massive energy deposits under 300 yards though. As for those massive 200 grain bullets from a 300 winchester magnum, they are made more for heavier game than deer. The expansion from the bullet is more suitable for heavier animals where first the bullet must pass through heavy bone and muscle, and then expand for the vitals: with just deer, over long range, that quicker penetration is more important for the clean kills: the vitals penetration is already there with either of the cartridges.

[model 70]

what makes the 150gr. BTSP's not suited for long range? not looking for a fight. just curious.

[rem 700]

BTSP's are an okay long range bullet, but something like a BST or an Accubond bullet perform slightly better. Go ahead and shoot the BTSP: I would definitely trust it for long range deer hunting, but I find other bullets will put the bullet closer to your crosshairs and expand more reliably under the different velocities it will encounter.

[Evan03]

from what ive found tougher premium hunting bullets like the nosler partition wont hardly ever exspand as well as any other no premuim bullets at any and all velocities.

in my mind core lockts are 100% better deer bullet. ive recoverd probly 4 of these from deer.

ive used nosler partitions tp put pin priks through deer each and everytime well i think i may hve recoverd one mushroomed 277 150partition from a deer. but i know for a fact that when tougher critters like elk are concernd the partition and the 270 go hand in hand.

i shot my elk more than once, umm more than two times and recoverd all mushroomed 150 partitions.

i like heavy balistic tips. theyre basicaly a big hollow point with plastic cap over the cavity in the nose of the bullet. upon impact with the critters fur the plastic tip is drover into the body of the bullet to initate rapid and uniform exspansion.

ill pick the 7mm due to haveing hopefully alittle less recoil than the 300win.

First off, you have to define what "long range" is to determine which caliber will suit you better. If you're talking under 700 yards you're not going to notice a difference between the 2 rounds when shooting deer. In fact you won't notice the difference in many rounds under 700 yds. Recoil will be a little stiffer in the .30. Shooting past 700 is another consideration. You have to look at bullet selection. The Hornady 162 AMAX has the best ballistic coefficient of any of the major mfgr's .284 cal bullets. You have to go into "custom" type bullet makers to get a better b.c. and you're looking at $1 per bullet (yes just bullet). The .30 has a better selection of high b.c. bullets which is vital to long range trajectory and energy retention. Both will run 180g bullets at similar velocities so if you're looking at that the 7 will win every time because of the better b.c. If you don't want to shoot a 200 or heavier bullet out of the .30 I wouldn't bother.

In reference to the btsp vs. "ballistic tip" question, it simply revolves around the ballistic coefficient of the bullet. Simply put, it's the shape of the bullet and how well it retains velocity. Polymer tipped bullets of the same weight typically have a higher b.c. therefore will shoot flatter. Again at "normal" hunting distances you will never notice (maybe 1" more drop at 400 yds). That being said, ever notice that most winning match bullets are hollowpoints? You can go to Sierra's web site and find the bc's of any of the bullets that they make. Hornady's site you can also.

If you're looking to shoot deer beyond 700 yards, stay away from Nosler ballistic tips. Believe it or not, they are too hard! They will not expand reliably at lower velocities. Most long range shooters are shooting AMAX or Sierra Match Kings or JLK's or other custom bullets on game beyond 700.
