Anyone using 120gr Hollow Points in 7mm-08?

Wondering how they perform on Deer and Coyote. Ballistics are practically identical to the 25-'06 using 120gr PSP's on the Remington charts.

i use 120 sierras. work fine, i guess. haven't had enough time to do extensive testing, though... once we get out of winter i'll probably start in on the 500+ yard stuff again and get some ballistics data gathered.

Try Hornady SST's :evil: (or Nosler BT's.)

120's Seirra took out 2 Texas deer a few years back. They work fine.

I reload and use the Sierra's 120's in my 7-08. Not one deer has moved anywhere but down. I have shot 8 shots and 8 deer. I love them. I am getting 3000 fps with them.

I'm not sure if the other fellas are recommending the 120 gr hollow point or not, but I'd advise against using a hp on big game as they open up very fast and can cause some very explosive damage on entry. A 120 gr soft point would penetrate very good and kill any deer though. I used to use 100 gr soft points from a .243, and 120 soft points from a 25-06 and they killed deer great. I've heard the 140 sp works equally as well in the 7mm/.28 cal on deer too.

FWIW - my FIL runs plain-Jane Rem. CoreLokt through his 7mm-08 and his freezer is full.

The 7mm load does not have the same ballistics as the .25-06 load. Although the bullets weigh the same, and have similar initial velocities, the 257 bullet is heavier and longer in relation to it's caliber. The .257 bullet has a higher ballistic coefficient and will retain it's velocity better over distance.

All that doesn't mean that the 120 grain bullet won't do the job. It most certainly will for deer and coyote at most any reasonable range. A 140 grain bullet will however retain enough velocity to actually be travelling faster than the 120 at some distance between 300 and 400 yards. It will also drift less in the wind. Couple that advantage with the extra weight plus superior sectional density. That's why I usually prefer the heavier bullets in a given caliber.

I don't have the foggiest idea where you came up with hp for the 120's sierra's.
They are SP.

a..yeah duh ...

I guess I actually read the part at the beginning of the poster's question that went something like this...

oops-Sorry for trying to direct someone straight without knowing off the top of my head what weight and ogive every manufacturer makes.

I'm told that the 120 NBT is tough enough for deer, one local hunter/gunwriter even shoots elk with them when he's on mixed hunts. He says he gets full penetration, and these are big Roosevelt elk. This is from a 280 Imp. He's a straight-up guy or I wouldn't repeat this.

Try the 120 TSX too, but there's nothing new or surprising about using light for caliber TSXs.

I guess I should have mentioned that I only use factory loads. It seems that all of the factory 7'08 offerings are in 139 or 140 gr except Remington, which offers a 120 gr hollow point. I've just picked up a 7mm-08, and I'm not all that familiar with this caliber other than all the good things I've read about it. I'll likely just use the 140's but wanted some feedback on Remingtons 120gr HP's. Thanks

90gr flat based hollowpoints drop whitetail just fine from a 6mm Remington. I can't see why a similarly constructed 120gr HP wouldn't work in a 7mm caliber at similar velocities.

The 7mm load does not have the same ballistics as the .25-06 load.

According to the Remington ballistics chart, both are very close.

500 yds.....Velocity....Energy.....Trajectory

25-'06..........1825........887........-44.1
7mm-08........1778........842........-44.9

Difference = 47 ft/sec...45 ft/lbs... .8

At 500 yds, that's practiclly the same to me. The shorter distances are even more closely matched. :)
