Exactly my point.the 140gr tsx will work fine for moose and elk as well.here is a link from another site where a fellow from saskatchewan(skeeter 7mm) used the 140gr to take both elk and moose this fall.You might want to read the results for yourself.Go to the bottom of the page.

Let me answer that question.Actually I have taken five elk and a moose with 140gr partitions out of my 7mmstw's with great results.However the muzzle velocity was 3500fps not 3250fps.
One of my hunting partners has taken two large elk with the 140gr partition out of his 7mmremmag with a muzzle velocity of 3200fps.
Last month another of my hunting partners killed a large bull moose with a 140gr accubond out of his 7mmremmag.The bullet penetrated the shoulder and the moose simply dropped.The range was 50 yards and the muzzle velocity right around 3200fps.
If I was still loading for my 7mm Mag I'd opt for the 140 gr. TSX for elk and moose, and for deer I'd like to the try the 120 gr. TSX-BT, should be a real good killer at high speed
you don't need an overly heavy bullet with an X design, they don't need it for penetration

I don't reload(yet) but I did come across some factory 160 gr Imperial for my Swede, my gun shot those rounds like a tack driver but sprayed 130 gr Hornadys all over. Norma offers a couple of different 156 gr bullets for a 6.5 as well as factory cartridges if you have the$$$$.ratherbefishin said:

I understand. My question though, is how they work compared to the 160 gr load? I am interested in knowing what others have experienced using the heavier bullet. That is why I made a point of telling manitou210 I was not flaming him.
I have killed several tons of really big game using 130 gr bullets at 3200 from a 270 Winchester. Have also shot several more tons using 150s and my impression is that the heavier bullets have killed the heavier animals a bit quicker.
When I say really big game, I mean really big. Most Alaska-Yukon moose bulls weigh in excess of 1200 pounds. Mountain caribou bulls are the size of mature elk, some of them over 800 pounds.

In short go with the 160's they will penetrate better than the lighter bullets. The Remington Ultra's are the worst penetrating premium bullets out there, they consistently expand down to the base in high velocity calibers and are not as effective as other premiums. If they are available in 175's they would be my first choice in that bullet design knowing their tendency to overexpand. A 160 partition will do all that is asked of it for your needs.

When I am getting quick clean kills with the 140gr,does it really make sense to change to the 160gr to see if the animal might die a second quicker?Besides almost all of the 140gr bullets exited so no more penetration is required.Furthermore if you are so concerned with killing the animal as quick as possible,why use a 270win when much more powerful cartridges are available?
Why Not I just used my 7mmwsm last Sat on a 200lb field dressed white Tail I gave my friend my gun to shoot, 3 bucks together at 330 yards in field, his first shot hit buck behind last rib in stomach, buck was hit second time in anters, he kept his head down and shook his head, then started toWhy not? said:
go at a fast walk he handed me gun and I hit him behind shoulder at 420 yards with a 140 gr nosler partition it floored him, this shooting was done off hand, I have had two different .280 Rem and the biggest bullet I have tryed is 150gr partitions

I like the 160gr and the 175gr. I have also loaded up 140gr bullets, but have not shot game with it. Other than shooting a little flatter I don't see the point. Remember that the 7x57 was a giant killer with 175gr bullets at 2300fps.
Plus the 140gr 7mm RM will net you maybe 100-150fps over a hot .270 with 130gr. bullets. Not that great of a trade-off considering how much more powder you burn.
Using the 150fps difference that you provide, the 7mmremmag will deliver over 400ftlbs more energy than the 270win at the cost of about 10grains more powder per shot.In other words about 7 cents more per shot for the extra powder used by the 7mmremag if you handload.I don't think that it will break many budgets.
140's :?: :lol: ....160's :?: :lol: .....?...I think I'll use 150's :shock: 8)
good reading guys, but is it really going to make that much difference?.... :roll:
or maybe I'll just use the Whelen with 225's...oh wait, they don't shoot "flat" enough....I'll just get closer. :?

i would use the 160s like others have said they pentirate better.
talk to ya all later

Who said anything about cost?
You said your buddy's 7mm launches the 140gr partition at 3200fps, right. My22" barreled M700 Mountain rifle in .270 launched 130 XBT's at ~3160fps. Lets have a comparison:
.270 Win 130gr. XBT
PBR 311 yards with 264 yard zero
400 yards -12.2 and 1631 ft-lbs
7mm RM 140gr Part
PBR 312yards with 265yard zero
400 yards -12.1 and 1728ft-lbs.
Virtually identical performance. What exactly is this advantage you are talking about?

Wholesale sports sell Seirra 160's in 6.5, so does Bashaw soprts, and Higginson powders sells Hornady 160's I believe.ratherbefishin said:

Do you really think that noone would notice that you chose bullets so that the 270 win would have a much higher ballistic co-efficient? :roll: I could do the same thing and compare a 130gr .277" round nose and a 140gr 7mm tsx to give the 7mmremmag a huge advantage.Additionally,my partners load is very conservative at 3200fps while your load is very hot.You are the one that gave the 100fps to 150fps difference and coincidently most reloading manuals have differences in the 100fps to 150fps range.In fact nosler lists a maximum of 3100fps for a 270win with a 130gr bullet out of a 24" barrel while they list well over 3300fps for the 7mm using a 140gr bullet also out of a 24" barrel for a difference of well over 200fps.When you sober up try comparing the same bullet design with both loadings at the cartridges design pressures and you will see that the 7mmrem mag does indeed offer an advantage over the 270win. :lol:
