Home Forums Hunting & Shooting Long Range Hunting 7Mm rem mag. 140 or 150

I have a rem sendero in 7mm rem mag. It is the old series with blues barrell. I have shot both 140 and 150gr nosler ballistic tip with equal groups. It will shoot either load around .5". I have shoot a few group of each that is better than that. I plan on this being my long range deer gun. 500 or 600 being my longest shots. Do any of y'all have any experience with both or either to recommend which bullet to go with. The bc on the 140 is 485 and the 150 is 493. Any experience or advise would be appricated.

I have a ton load of experience with the 150 NBT (not much with the 140). I hear rumor that the 150 is built a bit stouter but it may just be rumor.

Not much in the world I wouldn't take on far or near with the 150 NBT.

I have shot the 150 in another 7rm but I was wondering how much better if any the 150 would handle a crosswind.

For the past several years those are the only 2 bullets I've hunted with in a 7 mag. The BC's are too close to make a difference. In my experince I think the 150's are a little tougher but I think 140's kill a little quicker on behind the shoulder shots. Basically flip a coin IMO.

That's about where I am. A flip of a coin. The point of impact is 1" different with horizontal being the same. I guess I could try both and see which one works better. What do you mean tougher. Hold together better? I prefer to shoot deer in the shoulder, would the 150 do better with this?

On shoulder shots they both pass thru, I think the 140's may do a little more internal damage and perhaps a better blood trail, but it's not much difference. I mean really not much difference.

I shoot 154 grain Hornady "bonded Blems" I got off midsouth. Have yet to kill something with em, but they are accurate and fly good. Plus they were cheap. I think the BC on them is .525 and we were busting rocks at over 500 yards with em with ease.

Enrique, I think those are their 154 Interbond offering.

The 154gr Interbond (bonded blem is a perfect description) worst accuracy bullet ever in several of my 7mm's (lot#04-022)
OP was interested in Nosler.....the 160 Accubond is IT at 531 BC

Leave it to good old rockchuck.

I use the 150 BT in my '87 ADL/FS 7 Rem Mag. Load is 63 grs of H4350 with the 150 BT exiting the muzzle at 3100. Not a fast load but very accurate in this rifle.

I was skeptical of penetration until in 2010 I shot a 140ish buck at 160 yards. He was quartering towards me at quite a severe angle but had shown signs of leaving the area twice in the previous few minutes so I took the shot. Hit him in the middle of the rib cage and that bullet exited about 8" ahead of the tail taking a 4" chunk of spine with it. About 3 feet of penetration. You can see the exit behind the grass just ahead of the tail.

Rockchucker I couldn't get the 168 Berger to shoot. Wonder how the heavier 160 ab would shoot. The higher bc would defiantly help with the longer shot. I hope to try and stretch it out in practice soon. 5 or 6 is as far as I intended to shoot deer.

Rembo I shoot rl 22 in the 140 gr at 68gr. 3100 is about all I can get out of it and remain accurate. I load IMr 4350 in the 150. Have not chrono them yet but I don't figure they are doin 3100. I seem to have trouble making book max speed out of any of my guns.

I also shoot Rel22 under the 140 TSX in this rifle. 70 grs gets me 3300. Some barrels are faster than others.

Rembo,I took the same shot on the same size buck in Montana a few yrs. ago with 160 TSX @ 3000 FPS.I killed the buck but he ran about 100 yds. where I found him bedded with his head up, sick, but very much alive.

Since switched to 160 Accubonds with quicker kills.I know many love the TSX but the deer I shot with them acted almost like they were shot with a bow.

Never a problem with the 150 ballistic tip either.

The 154's shoot very well in my rifle, but to each their own. That's why all guns are different.

As far as the 150nbt go, I did have a client a few years ago when I was still guiding, that drilled a mule deer buck on the Kaibab at 425 yards. The deer dropped like a sack of bricks. Shot went off and the buck dropped.
If I remeber correctly, he was using 7828 behind the 150s.

140 and 150 kill the same in my experience. Some rifles will perfer one over the other.

I may have to try the 160 Ab. I don't know if it was the bergers or the heavier bullet but my sendero didn't like it. The best I could get was 1-1 1/4" groups.

Huntnfish- I shot barns in a 270 wsm last year and it wouldn't knock a deer down. They all ran 75 to 150 yards with no blood trail. I did shoot one at 60 yards downhill that went through both shoulders and came out neck, it fell. That's the Only one that fell

NMSSHOOTER,try 70.0 RL-25 with the 160 Accubond for starters.Several rifles seem to like it and you will right around 3000 fps.Seems to do a little better than IMR-7828.Maybe the TSX's we shot did not open up quickly? The accuracy was great I'll say that.

I like the 140BT or AB for a midwest farm where my longest shot could be about 500ish yds.

Wouldn't hesitate to use the 150 on elks...
