take 99 problems, and adding more drift to it certainly aint the answer.Lots of little things compound into a big fat miss..But we all know that

I watched a mule deer get plowed tonight by a 7mm 168 VLD at 500 yards in a 10mph wind, and I guarantee you that the dude shooting wasn't wish he was packing less BC around, especially after he stuck it right behind the shoulder. But WTF do I know... Smart guys opt for less BC I guess.

Now your down to 2" hotshot. I know you're a big time guide now, but you might wanna check yourself before you wreck yourself. But a smart guy can spot a kid at the cusp of making an ass of himself, but I still think you're a decent dude....

I think we're losing sight of the most important point here ... as 99 so correctly noted, the higher BC bullet will have more ricochet. clearly none of us want that ...

Paper ballistics are one thing. Actually shooting another, I promise you the advantages are pretty obvious in real life.


That pretty much says it all.

If wanting a 7mmRM "mountain rifle", I would go 700, stainless #2 or Rem Sporter, in an Edge MR handle (ADL) with Limbsaver. I'd likely top it with a VX3 3.5-10 with B&C or turret. Should go about 7.5lbs and I don't think I'd want one any lighter.

This one runs 7.75lbs
A M70 but set up like you were thinking JPro. And, it was/is slinging 168 VLD and yes... I like the BC. grin

168 VLD .619 @ 3,000 FPS
500 yards 10mph drift=13.3"
500 yards 15mph drift=20.0"
Velocity at 500=2,269 FPS

Margin for error, 6.7"


150 ABLR .543 (Litz)@3,000 FPS
500 yards 10mph drift=15.4"
500 yards 15mph drift=23.2"
Velocity at 500=2,178 FPS

Margin for error 7.8"

Difference in margins, 1.1"
Difference in velocity, 91 FPS

Unfortunately the "paper ballistics" apply the same to both and it assumes BC's are accurate since I believe Litz measured both and the ABLR didn't live up to its stated .625 in a 1:10. But doesn't take into account elevation, ability to judge wind, shot angle, atmosphere, shooter ability, soundness of the chronograph, range finder, each rigs particular capability, scope, yada, yada....but we'll just assume everything is equal.

Have at it..........

Unfortunately I only allow a 7" margin for error so the 270 would be out of the running on this one. grin

Looks to me like things sure do get dicey past 500 no matter what you shoot... smile




The 280 Remington is overbore.

The 7 Rem Mag is over bore.

ricochet factor ("RF") goes off the charts

If you run a faster twist barrel it can. There are some .277 cal bullets with that high of BC. You might run into some COAL issues depending on the magazine in your rifle.

Seriously I don't know why you want a sub 7.5 lbs magnum rifle. I think a 7-08 would do 90% of what the RM would do without all the recoil. I'm not recoil shy and realize that this isn't a shoot often rig at the range but a hard hunting rifle.

I have a M70 EW .270 in a M70 FWT Edge stock with a VX3 3.5-10X40 CDS mounted in Talley LWT it weighs in at 7 lbs 13 oz. It's fun to carry and pleasant to shoot as long as I'm not pushing 150's too hard. 2900+ with Mag Pro is reachable but 2790 shoots pretty nice and isn't as hard on the shoulder, but I stick primarily to 130's.



my Rem 700 lh 7 mag weighs 7lbs 4 0z. scoped, slung and 3 in the belly of the beast

I really like that rifle but wouldn't want one much lighter, I find recoil on it comprable to the .338, so not bad, but it does recoil

now the 7mm-08 in 5.5 lb. package.....suhweet lil pussycat

and she's kilt the last two moose I dropped

My Ruger M77 in 7mm RM was my only bog game bolt gun for 20+ years. Didn't know until I got on the 'fire that the rifle and ("Hit 'em again") cartridge both sucked.

Once the girls were out of college I started acquiring other rifles chambered for other cartridges. The number of elk I killed skyrocketed compared to the years before when I was using the 7mm RM.

That, of course, had a lot to do with the way I hunted and additional time I spent in the field and nothing whatsoever to do with the choice of rifle or cartridge. Nonetheless, the 7mm RM has languished in the safe, going after deer but not elk for over a decade now.

Yesterday I took the M77 in 7mm RM and Ruger MKII's in .30-06, .300WM and .338WM to the range. While all shot well, the 7mm RM shot the best, with both 140g and 160g North Fork bullets turning in sub-MOA groups.

Today I'm headed back to the range with my hunting buddy, who won't be able to make the trip this year. We'll spend a little time at 100 yards before heading to the 600-yard range. Still haven't decided which two rifles to take but am leaning heavily toward the 7mm RM as primary with backup still a toss-up. The long range shooting will help make that determination.

The 7mm RM is such a bad cartridge I don't know why it is still offered. laugh

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.

A good .30-06 is a 99% solution.

You guys Crack me up.

I'm sure at what ever range your flinging bullets at you will not squeeze the trigger if there's a chance you'll miss.

It is pretty funny at times, and while I'll never argue a 7mm bullet isn't better on paper than a .277. That said my largest mule deer should have never crumpled at 560 yards to a .436 BC Sierra GK according to some. In the real world of hunting there is no real difference between 7mm and .277 bullets as long as the shooter knows how to shoot his chosen rifle and cartridge.

However, the OP knows what cartridge he wants to shoot and is just trying to determine platforms that'll reach his goals. I can't argue against his choice the 7mm RM as it has proven itself time and time again in the field. Now I have my doubts about me ever wanting a 7.5 lbs all up rifle launching 180 grain bullets at 2800+ fps. It just doesn't sound like fun to me, I have a 7 lbs 06 and 165's at nearly 3K gets old quick at the range.
