OK, I necked down some 30-30 brass to 7-30. I necked it down till I had to snap it shut, false shoulder or so I thought. After firing about ten rounds I looked at the brass. Shoulder and neck looked fine, but there is some what of a brighter ring from the rim up to about 1/4".
Is this anything to worry about? The 7-30 brass that I fire formed before did not do this.
Should I leave the false shoulder a little farther forward?

I have some 700X that I used with the cornmeal trick. But I can't remember or find my notes on how much I used. Any one?

I don't believe that you have a problem. If you go to 1Bubba's website & look at Don Shearer and the Shearer/Bellm Index. You'll see your answer better than I could explain it.

Check your shoulder to head chamber fit with the barrel OFF the frame and allowing for excess distance standing breach to end of breach end of barrel.

Sounds like you are OK but may be worth a check with this method though when forming cases.

I believe that you just have expansion at the expansion ring at the web due to pressure. It couldn't hurt to check it further as Headstamp suggests

Jeff I make all of my 7-30 Waters from 375 Win. Brass it turns good and it is better brass for hot loads

I load for the Imp. version and I`d just use startingloads instead of the messy cornmeal stuff !From your description I`d say you have too much pressure , but that on the other hand is difficult to judge without seeing it !

Paul Dustin, why not just use factory 7-30? Or is the 375 brass some how better?

OK guys, let me ask you this, fire forming load what kind of powder charge are you using? I used 30.5 grains of IMR 4895 with a 140 FB bullet, is this to hot to fire form with??

JMF, yes the cornmeal is some what messy, but it made excellent brass with no problems when I tried this method.

Jeff

Jeff the 375 win brass is better brass you can load it hotter then factory 7-30 and I do not like the factory brass. I use the 375 win brass for my 30 & 357 Herrett

what kind of steps if any do You have to make to get the 375win down to 7-30
Trckr

TJ,

First, Welcome to the Board!

Second, we are not telling you.

Seriously, you could try a one shot deal with the 7/30 sizer or use an intermediate step with say a 30/30 sizer adjusted only so deep to position the shoulder in approximately the right area and then follow with the 7-30 sizer. An Ackley 30/30 sizer would be very good but cost prohibitive.

You also MAY have to neck turn.

What I did is to first adjust my sizing die with once fired factory brass and my gun. I locked down the ring and then I simply ran lubed .30-30 cases up in the die and loaded. Fireforming provided good practice. Result, .30-30 formed to 7-30.

However, I actually use the proper factory 7-30 cases in my 7-30 barrel. Don't like to mix headstamps when it isn't necessary.

JSH...while i really do respect you opinion VERY much.I do not understand WHY would you even think about forming your own 7-30 brass.....unless you were doing so from a stronger brass(375) for HOT loads.
Ebaco has the 7-30 brass so cheap and avalible.
Maybe you just have TONS of 30-30 brass laying around??
Do you just like forming brass??
Just wondering

FIREBALL

FB,

From what I read on their website, all their brass is formed from 30/30 brass, including their "375 Winchester" brass which is necked up.

One of the easiest forming jobs is making 7/30 from 30/30.

As you say, if you have a load of 30/30 brass, go for it.

Regards

Fireball, if you don't have half of a grocery sack of once fired 30-30 brass laying around you are living in the wrong part of the country. I have a bunch of 30-30 brass though, a lot of the guys I run around with shoot a lot of it and save the brass for me. But I do have a lot of brand new brass that I bought a few years back for under a nickel each. It might not be the best but I do have a bunch of it. Now if you want a laugh, I have about a hundred once fired 7-30's that came with the barrel, plus another half dozen boxes of new loaded ammo.
I am using the 30-30 brass just to see what powder, bullet, and OAL length is going to show some promise.
BTW, a fellow shooter here says the 30-30 brass is what his barrel seems to prefer over the 7-30, and 375???
Jeff

Hey Jeff
I have close to 100 pieces of Federal 7-30 brass. They are yours if you will pay postage. I also have a set of dies.
Rich
rbartman@dslextreme.com

Where is the new federal 7/30 brass coming from? I'm not finding it at midsouth or midway or any of the places I'm looking. I have 100 pcs of Eben Browns re-formed 30/30 brass. Am waiting on a Bullberry 7/30 imp. and Fred suggests new brass, but where the heck do you get it? I've got a couple of boxes of federal brass once fired from my current 7/30 (soon to be an anchor or a horse shoe stake). Any body have access to it I'd buy a bunch of it. Thanks, Jim......

You might try www.armsandammo.com, he has some once in a while. It usually goes pretty fast. I think that they manufacturers make a few limited runs a couple of times a year. I have seen him have 375WW, 7-30, 300 Savage etc.. on a limited basis. You might call midsouth and see if they would put you on a list, or check with them every other week or so for the 7-30 brass, I have seen it in their flyers that they mail out, but the last time I called them on some stuff they were already out of a lot of it. Bottom line on the flyers through the mail, if you see it and want it you better jump.
Jeff

BTW, this is for everyone. Why in the H--- does it seem that a lot of the calibers that work so well the brass is so hard to get? And if it is easily found how come so pricey?? It seems that if just the bunch here is interested in it that there would be a little more to go around. If 90% of us shoot this in a handgun form how many rifles are there around for some of the various chamberings, standard and wildcat varieties?

Maybe the rifle guys are smarter than us???? Don't hardly ever see any of them looking for brass to make a 7.62 whatchamakallit super duper whopper stopper??

Mike B had brought up the thought of a few individuals making various parts to assemble some barrels. Looks like at least one of us better tool up for die making and stocking some of the various brass.
I have blabbed enough on this, but I think the next time I see some 375WW brass or 7-30 brass I will get what I can afford just to help some of us out that need or want it. Not looking to make a profit, just so we can get out and shoot more, instead of looking for components.
Jeff

Poppy09,

Before you make a boat stake/tent anchor out of that 7-30 barrel let me know its story and what you might want for it. I might have a "project" it would be suitable for, if the price was right. thanks, Mike

Here how you do it. You start with a 30 Herrett form Die turn it down 8 turns in my RCBS press. You need a 5/16 neck so you will need to ajust for your press. Then you go to a 7-30 Waters FL die and run it in now you are done. no fireforming needed. make sure you use Imperial sizing die wax and not a lot of it.I just form some more up today and it may me think of this posting

Thanks Paul,

I'm assuming that is for the 375 Win brass?

Regards

Just received 200 pcs of new 7/30 Federal nickel plated brass from Beickrich Ammunition, Rockester NY. 585-248-3660, ask for Casey. He's still got a bunch of it at $30 per hundred. Nice folks, delivered as promised at the price agreed upon. They're giving discounts of course for larger purchases. Thought you'd like to know, Jim.....

Headstamp Yes this is with 375 Winchester brass. In the 2 7-30 Waters I have they work fine no neck turning is needed. I like to do it this way so I do not have to fireform them. The 375 Winchester brass cost more but you are not using powder and bullets to fireform and it is better brass then the 30-30 brass
