How many of you shoot 2 or more cartridges based on the same case?

Do you mean like a 270 ,25-06 30-06 or add to that 308 and that line

Or the 458, 338Wmag, 7mag and 264 Mag. Or 5x57, 257R and 6mm Rem.

Or wildcats like the 240, 250, 280, 340, 350, 380 400PDKs along with the 6.5 and 416 all based on a blown out 280 case?

I do. '06/280/270/25-06

well I have an 1886 45/70, a model 94 30-30, a 7 mauser and a 7.65 mauser.
so pretty much anything else I own rifle wise or cartridge wise
is based on those.

yes! several on 308 case, 30-06 case and 375 h+h case.

300 and 375 H&H, 30-06, 35 Whelen and 400 Whelen, 257 Roberts and 7x57.

I shoot 25-6. 270,3006 and 35 whelen all based on the 06 case.

I think that "based on the same case" is a little too broad and a little too vague. It can be argued that every rimless case with a .473" head size is "based" on the 7.92 (8x57) Mauser; or that every belted magnum is "based" on the .375 H&H.

If you narrow your definition, then how narrow do you get? The .270 and .30-06 have slightly different lengths, and the .280 Rem is both longer and has a longer base-to-shoulder dimension than the '06. Of all of the .30-06 "family", only the .25-06, .30-06, and .35 Whelen (and possibly the .338/06) use identical case lengths and shoulder datum points.

So you'll need to better define "based on the same case".

45ACP 30-06

see if some of these would qualify

17 hebee, 218 bee
17 mach iv, 20 vartarg, 221 fireball, 222 rem.
17 ackley hornet, 22 hornet.
223 Rem. 223 Rem AI
250-3000 Savage, 22-250

243, 260 Rem, 7mm-08, 308 win, 338 Federal, 358 Win
257 roberts, 7 x 57
06 derivitaves through 338-06
300 H&H, 375 H&H
6.5 WSM thru 325 WSM

Not many people realize....


Also using the same case is the 270 Newton 30 Newton 33 Newton 35 Newton 40 Newton.

Come on now yes I am talking about like 25-06, 270, 30-06 etc. Im not talking about well this started out as a basic belted magnum case and was shortened and the belt turned off and opened up to where it doesnt really have a neck bla bla.
Thats like saying all cars have a frame.
Im talking for the most part same basic case necked up or down with maybe minor other changes.

For those of you that do have you ever had near accidents nearly putting the wrong cartidge in the wrong rifle? Or go to the range and realize that you brought the wrong ammo with you?

I have a 7-08, 308 and 338 Federal. So far, I've never had an issue keeping my ammo strait.

25-06,.270,.280,338-06
have not made that mistake yet.

I shoot a 270 and a 30-06. I had a 25-06 that I rebarreled to a 6-284.

I have not mixed up the ammo for my 270 and 30-06. I did witness a man checking his scope on his 30-06 and couldn't figure out why he wasn't even close to the target. Turns out he was shooting 270's in his 30-06.

Nope not in the last 40+ years of handloading.

No.


Any that could be confused get clearly marked
and kept well separate. Even to the extent of
marking cases or for the 318WR, scratching out the 30.06.

I also try to avoid taking two guns of similar calibres to the range or hunting, especially if Spotlighting all night when you get a bit tired.

Quite a few of the "blow ups" I have seen here in Aus were the aftermath of a spotlighting night.

I do. 25-06, 30-06, (9.3x62 almost the same); 243win and 260rem (also had 308win); 300wm and 338wm.

I do though mine may not fit in the Medium Bore range.... I shoot 223/5.56 and 300 Whisper in AR's. All of my Whisper brass to date has been formed from 223. Haven't had mix up issues but haven't frequently taken both out at the same time.
I also shoot 500 Linebaugh in a Linebaugh revolver, 500 Maximum (Linebaugh Long) in a Reeder Ultimate Encore, and 50 Alaskan in a Nonneman Marlin M336. This is truly a case of if it fits - it shoots and the Marlin is marked for all 3.

Mat

I shoot more then one Wby chambering. Roy did like the 300/375 H&H case alot.

Ken....

'06 based right now. Next in line 7X57 based.

708, 308, 358
257 roberts, 7x57 8x57
2506, 270, 3006
416, 458, 470 accel
416 rigby, 500 accrel

One of the gun writers - I don't remember who - published an article last fall. I think it ran in the Sporting Classics or maybe Grey's.

Anyway, he told the story of how went out to the range with a Dakota 10 (? - the single shot) in .25-06, and also a bolt action of some flavor in 7mm-08.

He'd loaded Hornady tipped bullets - the red tips - for both rifles.

After a couple of phone interruptions (I mean, conversations) from home, he proceeded to put a 7mm-08 shell into the .25-06 Dakota. Of course, the rifle went

BOOM!

The chrony said something like 3700 fps

He went home, cooled off, and could find no visible damage to the rifle! He took it out again and basically found it no worse for the wear!

He finishes the article by saying he did decide, after all, to re-barrel the action. But the actions is just as sound as when it was new.

All's I can say is: WOW!

friar

I have a 30-30, a 6mm-30, and a 35-30.
I also have a 223 Rem, and a 7mm TCU.
I have a 358 Win but I no longer have my 308.

I have a 270, 280, 30-06 & 338-06. I have toyed with the idea of building a bunch of rifles in calibers all based on the 06 where shoulder angle and such remain the same with the only change being the bullet diameter:

6mm-06, 7mm-06, 8mm-06 and so on.

Why would the chronograph read 3,700??

That makes no sense to me at all, as the 7-08 has less powder volume than the 25-06 and on top of that, a heavier bullet AND it all went into a LARGER chamber. Squezeing the bullet down won't make it go faster!

AND, why would he re-bbl the gun?

DM

I now have tworifles that have cartridges based on the same cartridge. I had a 270 Win, I just got a 280 Rem. Both based on the '06
On firing the 7-08 in a 25-06 rifle. At first the chamber pressure would be much less because of the greater capacity of the chamber, but as the bullet contact the neck of the chamber the bullet will stop. The pressure will increase greatly, well above normal for either cartridge. Swaging the bullet from .284 to .257 would take tremendous pressure. This tremendous pressure would give the very high velocity.
In a situation like this, it just goes to show how good the rifle was built. If it had any flaws it would have exploded. He should thank Dakota for that.
The tremendous pressure from this can weaken the barrel. It may have been safe to use but it might have blown up on the next shot. Rebarreling is much safer than possibly dieing from an exploding rifle.

All .473" case head cartridges are based on the 8X57.

Higher pressure = higher MV.

I have 6mm Rem., .257 Roberts, 7x57, 8x57, and 9.3x57. I believe all of these are based on the same case.

All .473" head cases are based on the 8X57.

Is that the original 8x57j .318 version?

I have had several based off the same case in the past and still several that still are.

I run both the .204 Ruger and 6x47 Rem. I have a .25-06, .270, .30-06, .338-06, and .35 Whelen, and have owned at one time or another a 6.5-06, .280, and 8mm-06. I have as well .250 and .300 Savage rifles. Plus I owned a .303 British and a .30-40 Krag at the same time for a little while, kept the Krag and the .303 brass to use in my .30-40 in a pinch. I have a .358 and .243 as well.

That's basically what this fellow said! He actually shot it a little bit (a season or two) before deciding he'd pushed his luck far enough and had better rebarrel.

I looked on-line and can't find the article. I'll keep digging. It was a great read!

Pressure and velocity only have a rudimentary connection in a firearm.
For instance I can load my 30-06 with different powders - all to the same pressure and get a very large difference in velocity. I can also load say H4895 to a pressure of 50,600 CUP to get 2800 fps and then load H414 at a lower pressure of 48,700 CUP and get 2900 fps.

One could, theoretically load enough bullseye powder to generate 50,000 CUP and get less than 2000 fps - all with the same 165 grain bullet.

The difference is that the pressure is not an averge pressure all the way down the barrel. The pressure measured is peak pressure and the average pressure will be lower with faster burning powders. The time that pressure takes to reach its maximum is dependent on the resistance of the bullet to leave the case and begin travelling down the barrel. In a "good" load the peak pressure occurs between 2 and four inches of travel and remains high enough to accelerate the bullet all the way down the bore. If pressure exceeds a given amount then it peaks very fast and drops off very fast as well. This is why the powder that gives the highest velocity for a round in a long barrel will also give the highest velocity for that round in a short barrel. Detonations rarely give high velocities. The pressures are too "peaky" and do not last long enough to push the bullet very far. You see this when using a chronograph to watch velocities as you increase powder charges. Velocities will increase about the same amount as you add the same amount of additional powder - up to the point where pressures begin to rise very quickly. At this point you notice that the velocites increase less when you add the same additional amount. It is a warning sign that pressures are already beyond the optimal range for your cartridge/gun combination. You can test this by using a very fast powder (for the cartridge) in your own guns. (I do NOT recommend doing it because the difference between a slight over-pressure load and one that is dangerous to you and your gun is really very small)

223 and 6x45mm...

I have 270 and 35Whelen.

Talking of cartridges based on the same case does anybody use a 7X57 and 275 Rigby

I have a .308 and a .243 as well as a .30-06 and a .35 Whelen.
