Q's about the energy or a 30-06 and 7mmRM

[Walsh]

How much energy does the 7mmRM have compared to a 30-06 out to 1,000 yards.

I would assume the 30-06 would win because of the higher grain bullets it can accomodate. Am I wrong?

When I rebarrel my 7mmRM, I can't deside whether I should convert to 30-06 or not.

Thanks,

A .30-06 shooting a 200gr Accubond will give you 842 ft/lbs at 1000 yards. The 7mmRM shooting a 162gr A-max will get you there with 962 ft/lbs. The 7mm has higher BC bullets so it retains more energy despite being a smaller diameter.

Ok, let me ask another question, how much energy is needed to make a humane shot on a deer at that distance.

Sorry for the questions, I've been watching "Best of the West" on the Outdoor Channel, and they had a guy kill an elk at 890 yards with a 7mmRM and a 180 grain Berger VLD bullet.

One last thing, how much does a .308 have at that distance?

Thanks,

I dont have the exact data your asking for, however I would say for what you are asking, the 7mm Rem is suitable for the job. I dont think the money spent to change to a 30-06 would give a noticeable difference. Here is a link, check out the BC of the 160 gr Accubond which will be lethal on Elk. I currently own 2 7mm RM loading 140's in one and 160's in the other.

Your 7mmRM has common bolt face with 300 win mag.

7mm RM with 180 Bergers at 2950 fps has 1153 ft lbs at 1000 yards.

30-06 with 208 Amaxes at 2750 fps has 1050 ft lbs.

But there's a lot more to putting a bullet into an animals vital zone at 1000 yards than the amount of energy is has left.

Yes, I have considered the 300WM, but something is pulling me away..... what is the average barrel life for a 300WM, energy?

Yes, I have no intentions of shooting at an animal at 1,000, I'm just asking so I can know more about my rifle's capabilities BEFORE I start sinking money into it.

Again, what is the acerage barrel life and energy at 1,000 yards with a 300WM?

I'm at 1700+ rounds on my TRG 42 in 300WM, and it still shoots less than 1/2 MOA. Most 300WM shooters I know will set their barrel back around 1300-1500 rounds. Some will replace them. I would say around 1500-2000 rounds for a 300WM.
Also, a fast 7mm bullet with a good BC would be a good choice. The 7 Mag is an awesome caliber.

Been reading this discussion, and it's saying that the 300WM out performs a 7mmRM because of the bigger bullets, with the only downside being recoil and barrel life.

I know either one of these mags. will do better than I can, just trying to find which one is better.

It's a Chevy/Ford/Dodge question really. They both are great calibers with high BC bullets. The 300 uses heavier pills to do it. So, if energy was the deciding factor, I'd lean 300WM. A 208 A-max or 210 VLD will hit very hard way out past what most shoters can shoot.

Ok, thanks to all, I think that I will rebarrel to 30-06 just because I love the cartide and it's great history.

You'll have to get a new bolt as well. The case head is a different size. It would be easy if you kept a magnum bolt face, like for a 300WM or your 7mm Rem Mag.

Re: Q's about the energy or a 30-06 and 7mmRM

Yea, I know, I'll just get one from PT&G the way I want it, it's only ~$150. In my opinion, the output for the new bolt will outweigh the cost of the expensive factory 300WM's, or the 7mmRM's, 30-06 is much cheaper.

Right now I don't currently reload so it's only factory for me, hopefully next year I can have enough funds for a starter kit for .30 cal.
