Home Forums Reloading Big Game Rifles 7MM Remington mag. and 140 gr. Partitions

I toyed with the idea of building a 280AI but why get a wildcat when I can get a paltry 50 fps more using easily attainable factory brass and just might get even more with the heavy bullets. Then I also have a 270 and a 7x57.

What a bunch of nit pickers... Its all in your head if you think that a 140 is better than a 160 or vise versa.

Get yourself a pound of RL22 and start punching paper. BTW, I'd go with a 140 Accubond, and get the "BC" of a 160, and the speed of a 140. They seem to kill animals alright.

Mark:

Maybe you shoot at game at 4, 5, and 6 hundred yards, and maybe that is a responsible thing to do, for you. I consider 300 yards as max, and if I misjudged and it was nearer 400, there's only 2.8 inches difference.

At hunting ranges, as defined by me, there really isn't much difference in trajectory.

I wouldn't want to have defend myself from a bear with a 140 grain bullet in a 7 Mag., be it a Nosler Partition or whatever.

160 grain NPs in my 7 Mags. always go clear through Caribou. Maybe a 140 would too.

I seldom shoot anything past 200 yards I just happen to buy a 7MM Remington magnum that I like and want to use with a bullet that I can confidently use on deer to a max of 250 pounds from any reasonable angle. I might even use it night hunting feral hogs at very close range but mostly my 35 Whelen will pull that cart. I like the idea of the flattest shooting combination because deer a lot of time don't stand there waiting for me to come up with a rangefinder.

rickt300:

If I wanted to use a 140 grain in a 7 Mag. It would be the NP, like you were talkin about.

I may not have as much experience with the 7 Rem Mag as some on here, but I've been using it with 140 and 160 Partitions since the late 70's, along with a host of other cartridges; and when I don't mind lugging a 24" barreled rifle,and want to shoot something at (my definition of)long range, which is out to 500; the 7 mag and 140 Noslers Partition gets the nod.

I agree with Mark and Journeyman who have stated that the 140 @3200-3300 is flatter than the 160 @ 3100, as well, though not by much. I zero the "old way" with the 140 @3250 or so, which is 3" high at 100 yards; the 140 is POA at 300,and down 7-8" at 400; mid range at 200 is only 3.5" or so. I have had no problems "overshooting" with this combo (gimme a break)at mid range, and it hits about 2 ft low at 500.Recoil is moderate.

Today we have range finders (which may not work ALL the time, so I use 'em but do not rely entirely on them), but JO'C once wrote that the best range "finder" may be a flat shooting rifle zeroed for the longest point blank range that will not cause mid-range misses;even with all the high-tech assistance today,not bad advice. The 7 mag-140 Partition does the job as a long range outfit of ample killing power,and moderate recoil; I would not hesitate to use it on anything on the continent, cept' of course the large bears.

There is certainly nothing wrong with 140 partitions at 3300+, and a lot of game has been taken with that load up this way. However, yesterday I loaded up some 160 Accubonds, just to see how they shot.

Tried three different loads and they all went into an inch or better, at more than 3000 fps, from my old three-lug SAKO L61R. The fourth load was a tad over 3100 fps. Re22 is amazing stuff!

I may just give these a try on moose this fall.

Ted- if you get to using that 160 Accu on game let me know what you think.

That is one bullet I'd like to give a run in my 7 Mashburn.

It shoots well in my gun with 7828 but I've not beat on any game with it yet.

Yet...grins

Thx

Yukoner: That RL22 is good stuff. Goes to show what a shot of nitro will do for you........

You bunch of troublemakers, I chewed it over for a while and ordered 400 160 grain Partitions. I'll run them puny 140's in my 7x57.

That should last you. From SPS I hope?

RickT,
She'll hammer you a little harder (with the 160's) but 140 NP or 160 NP in the running gears and you'll need rubber gloves. I am with Bob on rifle zero. As far out (if you are hunting long range) but not too far as to cause a mid range miss and you can hold on at any reasonable range especially with the 140.

Yeah SPS has a sale right now on em.

Long as its a 140 Partition or TSX runnin at the 3300fps range...Id say you can do most anything a 7mmRM will do with that...lesser bullets might not hold up to high speeds and heavy game.

Agree with a couple of others...in a 7mmRM I'd go 160 at 3000+.

My experience with a Wby Mk V in 7mm Wby and using a variety of 140 grain bullets (including Partitions) was poor. One shot in particular at over 300 yards that hit an animal wouned by my buddy convinced me to go to a heavier weight. The shot hit the animal in the ribs just behind the shoulder, went down the middle, hit the offside hip and smashed it, then was found under the skin on the opposite ham! Started using 160 grain Partitions, far less meat damage, bang flops, even at 300 yards plus. For me magnums exist to throw heavier bullets, but that's just my .02!
Have a Great Christmas Guys!!!

Sounds like poor performance to me, hit the ribs, down the middle and smashed far hip and was found under the skin. Absolutely pathetic bullet performance!

No, not really rickt. Too light that's all. Too much speed, not enough mass and weight. Nosler Partitions are still my "go to" bullets.

Do what I did.
Push a 150 Partition at 3175fps and call it a compromise!

I don't usually post my experiences/opinions more than once + one followup on a thread EXCEPT for posts on knives and the 7mm Remington Magnum. Again, as if it makes a darn for most...I started with the 7 Mag "seriously" in the mid '80s and have used it now in the USA, Canada, Mexico and Argentina in the Americas, Scotland, England, Sweden and Norway across the pond, RSA, Zim, Namibia and Cameroon in Africa, and finally in Australia for over 40 species, not individual animals (best I can figure some 230ish of those) from roe deer, duiker and and dik-dik to water buff, sambar and eland, with a dozen and a half different bullets..and the 140s are THE TICKET in this chambering...period.

That pic above is of my 21st elk and probably 80thish or so whitetails with the 7 mag, and unequivocally 140s display better "killability" than any other despite bc, sd or xyzwqrpwhatever....and with no apologies that's just the way it is...

Merry Christmas...

Journeyman:I'll swing with you;only bullet that I've seen better than a 140 Partition is a 140 Bitterroot;just because of a wider frontal area and higher weight retention.It has a high DRT track record, but they're no longer made,so its moot.

The 140 at 3200+ is a great load for about anything,and I am not surprised at the results you've had in your extensive experience with the load.
