First go at forming 7-30 Waters brass

[Blood Trail]

Buddy I hunt with asked me to reload him some 7-30W. Having never fireform any brass before, I thought I give it a try.

I neck sized the 30-30 brass(annealed first), loaded up with 12 grs of Red Dot, added flaxseeds until it filled the case right at the neck, and stuffed a 22 cal cleaning patch to plug it.

I didn’t want to use bullets in this ordeal. I felt it would have been a waste trying to convert 150 30-30 cases, and I’m sitting on about 15 lbs of Red Dot.

I have two sleeves of slight corroded large pistol primers for the bang button.

All in all, they turned out pretty good.

Do you shoot them straight up in the air- and does roasted flaxseed smell good?
The reason I ask, I recall roasted Maltomeal smelling ok when I blew out some 30-30 to 38-55…..
My 7-30 shoots the fire forming loads pretty good with whatever bullet I’ve tried.

All I smell is gun powder and a lot of it. One shot fills a three car garage. I’ll have to finish the rest at the range. I tried rolling on of my wife’s brand new beach towels over the muzzle so I wouldn’t have the Neighbors calling the law. Blew a hole straight through it.

I’m in trouble if she finds out.

Blame it on the washing machine!

Looks like a big old moth to me, james

Looks like you now have a nice stack of semi disposable dishrags. Cut it up.

Looks good to me. I got into T/C Contenders back in the the later 90's. Not sure what inspired me to get a 7-30 Waters, but sure glad I did. A few whitetails would beg to differ, great cartridge for the size deer and the territory I hunted with it.

Fireforming, I was on my own with zero guidance. I just read what I could online and went from there. There wasn't a lot of 7-30 Waters brass to be found in my area, loaded or new. I'll admit the first time I pulled the trigger to fireform one, was one of those grit your teeth moments.

my dad (RIP) had a 7x30 Waters in a 14" muzzle brake Contender back in early to mid '90s. he bought a hundred cartridges of 7x30 factory ammo. then a few weeks later, we are at a gun show and i bought 500 cases. i didn't know at the time, that Dad bought 500 more cases. there was no need to reform 30-30 cases of which i had a plastic grocery full of 30-30.

the 7x30 is a really good deer gun, but i despise the muzzle brake. this year i'll take a 10" Contender in 30 Herrett as my deer gun. i have somewhere around 100 once fired 30 Herrett cases (made from 30-30 Starline brass)

Actually, I've found that all I need to do is run cases (W-W Head stamp) in my 7-30 Waters die and I get good cases after I then fireform them. But, had very poor success doing the same thing with new Starline .30-30 brass--crinkled shoulders on 70%. With the once fired W-W brass I had 97% good production.

I have a 7-30 JDJ barrel 14 inch. From what I can find out it is a 7-30 Waters that was rechambered by JD Jones with a sharper neck. I have a couple sets of 7-30 Waters dies but they do nothing for the neck. I am trying to fire form 30-30 cases to the 7-30 JDJ. I am looking for some kind of formula for the starting load. I have all the stuff to do it but just need some guidance on coming up with a powder charge. Any feed back would be appreciated first time fire forming and working brass this much.

Email SSK and ask them to send you the load data. They sent me data when I purchased dies from them.

I agree about the data from SSK, I’d do that too.
If you run the 30-30 case into your 7x30 (or 7-30JDJ) die slowly, you will form a false shoulder to headspace the case. Your Contender should close with some resistance when you’re at the right place. Set your sizing die for that measurement.
Load those cases with cornmeal or whatever;
On my 7-30 Waters single shot, I just used some bulk fmj bullets over mild loads and they turned out just fine.

Hey. Brother. Assuming the 7-30 JDL, I would assume the process is the same as what I did, with the exception of using 7-30 JDL to neck size first.
