7mm
 

Hey guys. Just wondering I shoot a 270 win. I"m looking to get a bigger rifle such as a 7mm rem mag. I'm looking at the browning x bolt. I was just wondering is there a big difference in recoil between the 270 or 7mm. Just wondering.

I dont think my 7mm rem mag remington cdl kicks any harder than my rem 7400 30.06! And it shoots great!

I just moved from Tikka 270 win to x bolt 300 wsm. Recoil is almost the same. Some practice and you'll be fine.

It will mostly depend on how well the x bolt fits you, as well as the grain of bullet you use. Make sure you position the scope to give you 4+" of eye relief and let her buck!:D

I went from a 270 to 7mm rem mag last year . more barrell lift and bang but recoil wasn't really a problem. Then again I also shot a lot of .303 down an old enfield and that one kicked like a mule so I may have been comparing it to the 7. I am shooting the sps with a cheap stock

If your going to make a move up.. MOVE BIG!!

300 RUM!!!

Good luck
Jamie

If you're going to make a move;
Move this thread to the "Guns and ammo" section where it belongs.

Just a question but other than on the tables and numbers can anyone tell me first hand that game goes down any quicker when shot with a 7mm rather than a .270? I cant see any evidence that the game notices a difference between a 30-06 and a .270 and the 7mm is only incrementaly superior to the 30-06 in killing power, just asking.

Thats where it is yah dink:lol:

Thanks Robin:wave::lol:

I really think that this isn't a huge step. However I think it is a good step. The bullet selection for the .284's is incredible. Especially if you are a reloader. Great ballistics for these bullets may have a desirable appeal to some that may want to try their hand at the longer stuff. Recoil is stiffer but with a good fitting stock and a decent pad it isn't crazy. I like both but give the edge to my 7 Rem.

I have the x bolt hunter in 7mm rem mag and recoil isn't an issue. The recoil pad that it comes with make the recoil a non issue. Great rifle, I am very happy with it so far

I used to have both. The deer and moose can't tell the difference. It's not enough to make me move up, but shooters split finer hairs than this. I would go 300mag and never look back.

According to the math the 7mm rem mag will recoil 33% more than a 270 in equivalent wt rifles.

Having chronographed numerous rifles in a pletoria of calibers I can tell you your not making much of a move going from 270Win to 7mm Rem. Mag.

I would have thought with all that extra powder the mag would be a bit faster

A bit is the operative word.
Not a bunch or a lot but just a bit.

Put a 24 bbl on a 270Win, and stack factory up against factory, paying heed to the sectional densities of similar constructed bullets, and you'll be amazed.

Reloading widens the gap a bit more, but then again with the advent of newer and better pressure trace technology has found the 7RM is prone to wild pressure spikes and variations, so staying within SAAMI spec on pressure has further erroded the once wide gap between the 2 cartridges.


I think the passage in the last few Speer manuals spells it out best

"Seldom will either handloads or factory ammunition match nominal factory ballisitcs in a sporting rifle and there is a great deal of velocity variation among sporters in this caliber." pg. 400 Speer #14 Reloading manual

For a substantial move up in the "bigger" category...I'd suggest moving up to .338WM.....but that's just me.

with the 26" barrell compared to my old parker 270 with the shorter barrell , I noticed quite a difference but mostly in noise and barrell lift. what would the difference in fps be between 270 150 grain rounds and 7mm rem mag 140 grain . approx.

270/7mm
 

x2

I shoot an x-bolt in 270WSM (which I understand to be very, very similar to a 7mm) and recoil is definitely not an issue due to the stock configuration and the recoil pad Browning uses on this model. I find the x-bolt to be a great shooter too - one of my "go to" guns.

Well your using two varing bullets in your analogy the Sectional Density of a 277" 150 gr. is 0.279 while the 140gr. 0.284" bullet is 0.248
The on game performance of the two will be totally different.(given similar constructed bullets)

Try comparing a 130gr. 0.277" (SD 0.242) and the 140gr. .284". Likewise the 150gr. 0.277" SD roughly equals that of a 160gr. 0.284"bullet.

7MM RM 140's in factory and a 24" bbl. I'd suspect real world velocities of about 3000fps.(never chronied 140's, but I have on 150's and 160, and 175's)
270Win velocities out of a 24" bbl, with 130's expect a real world velocity of about 2950fps.
Hmm lets see what that gets us for trajectories.
130gr. .277" Nosler BT @ 2950fps and a 200yd. zero.
300yds -7"(1565ftlbs) 0.343sec TOF
400yds -20.5"(1322ftlbs) 0.477sec. TOF
500yds -41.5"(1110ftlbs) 0.624sec TOF

140gr. .284" Nosler BT @ 3000fps same 200yd zero.
300yds -6.5"(1843ftlbs) 0.33sec TOF
400yds -19" (1590ftlbs) 0.460sec TOF
500yds -38" (1366ftlbs) 0.598sec. TOF

I guess if you feel a couple inches less drop and a couple hundred ftlbs constitutes a big enough difference to you then the 7mm RM is a big jump past the 270Win.

IMO it aint a big enough gap to haggle over, moving to a 30 cal mag from the 270Win is a bigger and more noticable difference, but alas that is not without it's own shortcomings.

good info thanks , really not much difference there. Doesn't the longer barrell (26") make any difference?

Sure does it makes the rifle longer.:lol::wave:
Chrono'd factory ammo thru a 26" bbl, equated to only a gain of about 40fps over it's 24" counter parts.

The 270 Win is closer to the 25/06 than it is to the 7RM. Whatever velocities a 270 can do with the 130, the 7RM can do with the 150. Actually the velocities of the 150 7RM will be abit higher although not much.

The 7RM isn't at its best with the lighter bullet weights, it starts performing best starting with the 160 and really comes on with the 168 to 180 bullets.

All else being equal, there is a discernable increase in recoil but it's well within the limits of most shooters.

Nonetheless, the appreciable performance difference of the two cartridges on game is slight on deer sized game. On elk and moose, abit more so.

In short, although the 7RM offers greater performance than the 270, the 7 does not offer a big enough increase to justify buying a 7RM if you already own a 270. As mentioned earlier, if you want a really noticeable increase in power, move to the 338 Win.

If he is asking about recoil the 338 win mag may not be in his near future. If you want a step up without a lot more recoil I would move towards the 30-06 with its versatility (110-250 grain) or a even a 300 WSM at the upper range.

People always bring up the avalability of more bullets when talking about 7mm or 30 cal cartridges over. A .270 can knock down anything that can legaly be hunted in this province with the proper 130 grain bullet, then you have the 140 and 150 incase you want a little more SD so I never understood the relevence of this argument. I havnt seen any difference on moose sized game between the 30.06 and the .270, they both work great but neither has much of an edge over the other. I was just wondering if a 7mm was enough of a step up to get that edge, which doesnt seem to be the case.

The only difference really that I could see with the 30-06 over the 270 is loading it up with 200-250 grain flat nose bullets giving it some real potential for penetration. Gives you a great bush rifle with a flat nose bullet.
Your entirely right, in reality what is the difference really with a properly constructed bullet for most hunting scenarios where you don't really need a high sectional density, get a high quality bullet with reasonable sectional density and you could hunt any non-dangerous game in N.A. from a 25-06 on up.

Why a great bush rifle? Are you meaning that the bullet won't deflect? I thought that was an old wives tale.

Whoaa, don't go putting words in my mouth brother, hehe, it can serve as great bush rifle in the right setup that is inherent in big lead velocity and its trajectory, and having great penetration. I think of bear baiting, bear protection, heavy bush hunting, sitting over a mineral lick type of gun. Attach the scope and your ready for open country.

The only reason one might consider a "flat nose" bullet is for usage in a tubular magazine, which usually comes in .35 Rem, 30-30, .444, 45-70 or .450 to name a few. Bush guns are usually thaught of as the heavier and slower big bores. In regards to the recoil differences between a .270 and 7rem, why even worry about that? Why have a .277 and .284 caliber for a mere 0.007" difference in the same rack? not worth it. Go bigger, way bigger like .338 or .375 if you really want to make a difference.
