243 win, 260 rem & 7/08 rem

Dumb Question

I currently own a 243 win and considering acquiring a 7/08 rem as well.

Just wondering if it is smart to own both, just because of the general similarity of the ammunition.

I know we are ALL extremely careful, BUT is owning some combination of 243 win, 260 rem & 7/08 rem just asking for trouble?

Will any of these cartridges accidentally chamber in the wrong calibre?

I don't want to risk such a stupid, stupid accident - it might be better to step-up to a 308 win instead of the 7/08 rem.

What do you folks think? Does this happen in the real world with these three calibres or is it all in my safety-conscious head?

It happens more than you might think. A friend of mine has two identical savage rifles, one in 30-06 and one in 25-06. He grabbed the 30, thinking it was the 25 and fired several rounds at a target before he realized something was wrong. Luckily, there was no damage to anything.


I think the key is to not have two rifles that look exactly the same. If you can easily tell which rifle it is which, then it should not be an issue.

Just my thoughts.

That is, of course, if you are diligent about checking which ammo you grab.

Thanks for response Trace.

We're always careful but Murphy gets a vote too eh?

One moment of inattention because you were tired or some other (should have known better) dumb human mistake that we'd never make under normal circumstances and;

>K A B O O M<

Yeah. That 308 win is looking better and better.

I have not mixed up any ammo so far and hopefully never will, knock on wood and I hope I didn't just jinx myself Lol

It is good that it is in your head, it helps to be aware of it.

My wife and I have identical 7mm-08's but they use different loads with several bullets. However we know how to tell them apart and I also use different brass for each one so we don't mix up the ammo. Also, I neck size so the ammo from one doesn't fit the other.

As far as the cartridge selection I'd go for the 7mm-08, I've been using it for 30+ years and it gets the job done as long as I do my part. I use bullets from 100gr to 168gr depending on the need and game being hunted.

Hope this helps and stay safe

In theory you wont be able to chamber the 7/08 into either of the smaller chambers, or the 260 into the 243... so the only way you can make a mistake is putting a smaller caliber into a larger bore... this cant be dangerous to the shooter.... just wont shoot effectively.

I have mistakenly chambered the wrong ammo but slightly different than what you have talked about... I was testing two rifles one was a 7mm saum and the other was a 7-08. After testing the 7-08 I put the rifle down and picked up the Tikka T3 7mm saum... a friend interrupted my for a chat, and when I turned back to the testing I accidentally chambered a 7-08 round in a saum chamber, as fate would have it both the saum and 7-08 have very similar head space so it chambered perfectly but without the support of the right chamber when I pulled the trigger the case ruptured, the mag blew out the bottom and the plastic bolt shroud blew off the back of the bolt... lucky for me I was wearing safety glasses etc.. So the projectile was the right size for the bore but the chamber was not the right size to properly support the brass. Lesson learnt....

I currently own rifles in .243, 7-08, and .308. I've never had a problem using the correct ammo in each. If your intention is to broaden the size/weight range of game you can hunt; then adding an additional rifle is a great way to do this; and have the pleasure of having a "new" rifle to work with. If you want to simplify, perhaps you could consider selling or trading the .243, and getting a really nice 7-08. The range of bullets available in 7mm is phenomenal, and you can literally cover ground hogs to elk with the 7-08. If I didn't already have thousands of .308 cases, and a wide assortment of match and hunting .308 bullets (from years of target shooting and hunting); I'd be happy to sell my .243 and .308 rifles in favor of the 7-08.

Hi Dumb Question!
In terms of your alternate choice you have the same issue, the 308 has the same parent case as the 243, 260 and 7mm08 so any of the smaller diameter cartridges will theoretically chamber in one of the larger diameter bores. Different bullet choices / ballistic tip colours would maybe help as well as neck sizing to fit specific bores but ultimately this comes down to attention detail.
Agree with Luiz here, all cartidge choices are compromises but I chose the 7mm08 for bullet range, you can load down to 243 level with light projectiles at high velocities for small game or load up for big game to 308 levels with heavy soft bullets at slow velocities, either way used responsibly at reasonable ranges it's a winning combo

Re: 243 win, 260 rem & 7/08 rem
Thank you all for your valuable responses.

I love my 243 win & funnily enough Trace - she's a Savage - in model 12 LRP.

I freaking L O V E this absolute deathstar of a rifle, and she's being used for deer at close range.

She is awesome on Fallow under 200m with 95 gn projectiles, but legally she's not enough for Sambar in Victoria.

I am based in NSW where .22 short is legal for Sambar, but want to be as humane as possible - but sadly I can't tolerate recoil - due to super-soft ears - (hanging my face in shame) - we are not to be trusted with moderators over here.

I can easily handle my 243, so I'm assuming the 7/08mm rem will be just that little bit more of a GOOD thing.

I also need the bolt on the correct (left) side of the rifle. Thinking very seriously about a Tikka Lite Stainless in 7/08 rem in LEFT hand action unless you can suggest better (Yes have the books).

Re: 243 win, 260 rem & 7/08 rem
go the big brother of them all...with same case.... .35 calibre projectile has to be just that little bit better for the big deer.
if you went 7mm its only a little bit more than 6mm the .308 is 7.6mm so go the 8 option and have best of both ends of spectrum...not counting the .22-243 of course.
if you cant suppress and have sensitive ears...see if longer barrel is option.

Hi, DumbQ. DumbA here. If you're intent on hunting sambar in Victoria, then you must get something legal. If your personal comfort-zone is <=200m, and your quarry is up to 50kg, you might as well get something that's not just marginally capable. If your hunting will be limited to NSW, I'd follow Nathan's advice in the 243 knowledge-base article - a copper bullet for the Sambar (for penetration), and a cup&core bullet for the smaller deer. Your death-star is more than capable for Sambar within 200m. A guy in my elk camp last year shot a 50kg elk bull at 30m 4 times with a 308. Shot-placement was not his forte. One broke a foreleg. Within 200m, your gun is fine. Past 200, I'd look at something with some authority.

Re: 243 win, 260 rem & 7/08 rem
Hi DQ, it is important that you understand that recoil is as much relative to the stock design as it is to cartridge power. A .30-06 wearing a Clive Judd stock shooting 208gr bullets at over 2600fps produces no more felt recoil than a 7mm-08 shooting 162gr bullets at the same speeds from a Tikka T3.

There are now many plastic stocked rifles which produce considerable recoil. Until you have experience with different rifle designs, you cannot really make a suitable cartridge choice with regards to your perceived recoil tolerance levels.

As Mike said, the .358 is a good choice for Sambar. It will however be a build rather than a buy (along with a suitable stock).

Re: 243 win, 260 rem & 7/08 rem
AS you say that you are concerned about your hearing, as well as felt recoil, you may like to consider the 308 ?

The report of the 308, loaded with 2206H/H4895 in a 22/24 inch barrell will be far less vicious than that of the 243. Unpleasant blast and noise adds to our perception of recoil.

As has been said, stock design has a lot to do with it also. I have used two rifles that are almost identical ballistically (velocity,charge weight, etc) except that one uses a 15% lighter projectile and weighs at least 1.25 pounds more.

Guess what, the heavier rifle, with the lighter projectiles has far more felt recoil, and a very different stock design.
