Forming 7 INT brass
Posted: Tue Nov 12, 2019 6:48 pm
The original instructions to form the 7 INT years ago said to start with 300 Savage. Just run it up into the 7 INT FL die and you then just needed to check OAL and maybe a slight trim.
Well as many of you know trying to find 300 Savage brass can be a real challenge at times or if you find it you pay an arm and leg.
I found another cartridge that is cheaper and easier to find and works just as well as 300 Savage.
I took the tapered decapping stem out of my durachrome 7 TCU FL die and inserted it into my Redding 7 INT FL die.
Lightly lube up a 22-250 case and use some good lube on the inside of the neck and presto you have a 7 INT case.
There is only a few thousands difference in the resulting case but you would probably trim a little just to square up the neck.
I haven't fired any of the reformed 22-250 brass but suspect I will need to blow out the case with a good fire forming load.
Might not be that many 7 INT shooters these days but wanted to pass on a tip to make new brass.
