Difference Loud 7mmRM vs 270w

7mm RM should be a bit louder than 270 if in the same barrel length, but even firing side you might not truly notice a difference. If a 7RM is uncomfortable for you, I would challenge the 270win likely will be as well. A linear compensator on either might sufficiently reduce your experienced concussion such you would be able to better tolerate either. That would be my first step before buying a new rifle.

The real answer, the real solution, however, is that you should be using double protection for these highpower rifle cartridges. Plugs and muffs, always. Three rounds of any rifle cartridge can and will cause ringing in your ears, and can and will cause irreversible hearing damage.

Be grateful your ringing stopped after two days. Mine hasn’t stopped for 21 years so far, I’ll have my wife email you when I die, so you’ll know when it finally does stop as a data point for your consideration.

I agree 100% with what @Varminterror posted. Many years ago when I was first getting into hunting with a handgun, I took one shot in the field with a Thompson Contender chambered in .35 Remington with a 15-inch barrel and a muzzle brake. It was Saturday afternoon. First and only shot ever with that gun without hearing protection. My ears immediately hurt, and the ringing didn't stop until late Monday. I was sure that I had permanently destroyed my hearing.

In God's providence, the ringing did stop, and my hearing does not seem to have suffered permanent damage (a dog barking a block away can still wake me up at night). But the Monday after taking the shot, I ordered a set of Peltor Tac-7 electronic ear muffs (a new and expensive item back then) that I have worn every hunt since if hunting with a handgun, and most hunts with a rifle. I always have hearing protection of some sort with me, and don't like to take even one shot in the field without protection of some sort.

Hearing protection always. At the range, double up: plugs and muffs.

I hope you're wearing ear protection. If you are, wear better ear protection. As Varminterror said, double-up on your ear protection. Either that or pay for it the rest of your life - hearing loss is permanent.

I'm not familiar with the SportTac model. The Tac-7s have stereo microphones, so sound is directional; no problem telling where sound is coming from.

I also use the Peltor Tactical Sports for competition in pistol sports. I add in a set of disposable foam earplugs if I get the big rifles out.

After getting my ears rung by the brake on my 450 Bushmaster when hunting I started hunting with ear pro too when using the 450 BM. For hunting I bought a pair of Walker Silencer Ear Buds. So far they are pretty good, the overall sound quality is not as good as naked ears but still pretty good while giving you sufficiently good protection. Despite the slightly worst sound quality, in someways, they are better than naked ears as they do amplify sounds. I was able to hear a squirrel climbing on the bark of a tree at nearly 80 yards when the wind was calm last winter.

You can also use them as Bluetooth headphone with you phone too.

Earpro!

My hearing is very good for my age, but my right is noticeable degraded from a single cylinder of .357Mag in my early 20s.

In my experience, good plugs inserted correctly are enough. I've never experienced discomfort or ringing from my own rifle.

That guy with the braked .17/BMG Eargensplitten at the next bench calls for muffs over plugs. . .

Buy one of those cancelling noise ear protectors. You can hear what’s going on and shoot all day. I’d keep the 7mm.

Thank you very much for your quick reply. I am starting to use "peltor spor tac", they work well but hunting with air it is difficult to find the place of the sound. I hope it is until I get used to it.

Some info for you.

• A 7mm Rem Mag should be expected to fall somewhere between 157-160dB.

• Your Peltor SportTac muffs have an NRR of 26 - this means it will reduce noise by 9.5dB [(26-7)/2 = 9.5].

• Sounds over 120dB can cause immediate and irreversible damage to your hearing.

158-9.5 = 148.5dB, which is still greater than 120. THOSE MUFFS ALONE ARE NOT ENOUGH.

Ear protection! But modern hearing aids are a lot nicer that the old ones. Your choice.

Hello friends, I currently have a very accurate Sako 85 in 7mm RemMag, but I am very sensitive to noise, I find it very loud, do you think that with a 270 Winchester the difference will be great? With the 7mm when I shoot 3 times in a row my ears ring for a bit. I once did a round of 10 shots in a row and my ears rang for almost two whole days, since then I became afraid of the sound.

thanks!!!

Is a suppressor legal where you live?

You'd still need ear pro, but it tames down the noise and concussion quite a bit.

I would recommend plug and muff on the range. NRR plugs at 26-32 and muffs at 26 should make the shooting much more enjoyable. The noise cancelling plugs or muffs are fine for hunting in most cases

A few years ago I was hunting with a 3006 semi-rifle, with 22 ”barrel, and I can assure you that I have noticed the change, but the 7mm is fabulous, it would cost me to get rid of it.

Electronic buds or surefire ep3s for hunting, add muffs for target practice.

I use those spring loaded plugs that hang on my neck. They don't work as well. But they are always there and easily put in.
I too had issues with tracking sound direction using electronic muffs.

Suppressors are prohibited in my country, but maybe try other peltor, and maybe buy a 308, for shooting and hunting, so I can see the difference.

Noticibly quieter cartridges would be .30-30, .303, .30-40, 7.62x39, etc. Can I tell the difference between a .308 and a .300 win when I pull the trigger? Sure, can I tell the difference between it and either of my buddies' .270s or .30-06s? Nope. I'm not saying there isn't a difference, but too loud is still too loud, my 20" non braked .223 is the nicest blast I currently run regularly, when the wind is at my back with ear pro in, I almost don't notice it.

Put in ear plugs under those electronic muffs. You’ll attenuate the pressure sufficiently to reach a safe level for your hearing.
