I'm planning on resizing some 30-06 casings to .270
do you guys scratch out the stamp or sand off the base of the casing or just police really well where you put your resized cartridges?
I dont own a 30-06 any longer but do hunt with people that do, just want to avoid the confusion.
 
Leave the head stamp alone. If you remove any off the head the primer will sit high possibly causing a slam fire. You also can’t make up for it by reaming pockets deeper as the front becomes too thin. 270 brass is easy to find why not just us 270. You could also trade so that you would have the proper cases.
 
thank you, trading may be an option, buying? ahh im cheap, got few hundred cases of once fired by me from when i had a rifle in that caliber,
Ill just police the ammo when in camp with them 30-06 chaps
 
You may discover that your re-formed cases are a touch short in the neck - the parent case for 270 Win was the 30-03, not the 30-06 - but I believe 30-06 has been resized and used as 270 Win since a long time, by many people. As you note - any time you form a case from something else, almost always end up with the wrong head stamp - and sometimes they even chamber and fire in the original chamber - I made some 7x61 Sharpe and Hart from 7mm Rem Mag that do exactly that - the head stamp says 7mm Rem Mag, not what the thing has been re-formed to be - part of the "challenge" of making cases from something else, I presume, or relying 100% on what that head stamp says.

Murphy could make an ammo switch happen - but only if it is a shot on a world class trophy buck.

It is not a major concern. If a shot is taken, not much will happen, except a shot about equal in power and accuracy as throwing the bullet by hand.

If your ammo is in your own ammo box, and is clearly marked as 270, not much chance of someone else using it in a 30-06.
 
Although I think Ganderite is correct that "not much will happen" if a 270 Win is fired in a 30-06 chamber, other instances might be a bit more lively - we found a number of "weird looking" 308 Win that had been apparently fired in a 30-06 chamber - whatever that guy had been experiencing while shooting was not "normal". And I do not think you will loose eyes or fingers by firing 300 H&H in a 300 Weatherby chamber, or 7x61 S&H in a 7mm Rem Mag, and I know for sure nothing untoward happens when a 30-06 has the neck opened up, .366" bullet is seated, and that is fired in a 9.3x62.
 
I Have made 6 x 45 brass from .223 Remington, and what I do is blackout the headstamp with a black sharpie

Yes, it would rub off, eventually, but my thinking is that if someone were to pick it up and look at the headstamp, they would see the black, and think twice (at least i would)

I do a lot of wildcats etc, and I dont think I would bother with 06 to 270. 270 brass is very common, why go through the effort? - dan

im cheap, i got press, i got lube, i got time,

I have no doubt that i will accumulate .270 brass with time, but at present i have lots of 30-06, kind of overspent lately on my hobbies, and am definitly not going to use this ammo for any shooting competitions, plus it gives me something new to learn
 
When I was reloading 308, anyone at the range looking at my ammo would see head stamps from 270 and 30-06 (yup, I cut them down ) as well 243. Now I shoot 338-06 so, clearly, head stamps don’t matter.
 
I have 458 Lott made out of 375 cases not to worried about those and put black felt tip marker on the cases that are resized and all is well. Was common for guys to use 303 Savage in a LE also. I say just do it and be safe.
 
Based on my experience in hunt camps, the danger is not someone using your ammo in error.

The bigger danger is them deliberately buying ammo, but the wrong ammo for the rifle. For example:

One guy thought he had a 30 ought 8, and was shooting 308 in a 3006. It worked fairly well until one day someone noticed that his empties looked like rimless 444.

I have seen several instances where guys had M94 rifles and assumed that they were 30-30. Nope. 32 Spl.

And one guy insisted he preferred 303 Savage because it did not kick so hard (in his LE).
 
that is funny

an idea is that the rifle this ammo is for will be a young lady’s first gun, so considering how i keep on stressing on my kids to always check that ammo is correct to the gun, i’ll make sure to have a proper stamp casings by the time kid gets to shoot it
 
I have used lots of .308 Win brass for my 7-08 and dropped one outside our moose camp and someone else picked it up and gave it to the only guy using a .308. He sat there for a few moments looking at it as he knew it wasn't his brand and it looked funny. Finally it twigged on him what this shiney round was. Of course up came the what if he fired it in his rifle question. I said probably nothing but wait till the camp is packed up to move out in case he had to pry a split case out of the receiver. He said maybe in someone else's gun!
So I guess the answer is to check your ammo before loading into the firearm for any defects. Except in desperation when you are digging in your pocket for more rounds after you have emptied your rifle.

Think I wohld just trade for correctly labeled brass if you dont want to confuse the kids. - dan
 
The 270 out of 30-06 brass is no big deal, you fire them in a 30-06 they will just turn into 30-06 again.

I hear you on the kid thing though. When I got my daughter her 7/08 I was going to make brass out of 308 and a bunch of quality 243 that I didn’t need. She was the one who pointed out the head stamp would be wrong; and when I pointed out that it didn’t matter she said it might not matter to me but it mattered to her. Rather than argue with a 12 year old girl that had just finished her safety course, I used the 7/08 brass I had. Even 50 cases lasts for a long time if you’re not hot rodding them.
 
Most experienced guys can have ten cartridges sitting on a table and can name them all from 15 feet away. Having that said, I converted thousands of 30.06 brass to 8x57. I mark the boxes and I know the difference to see them.
