Today at the Bench.....

Finally finally finished that 30-06 brass, at 25 a day, it took the whole week last week. Now I’m started on 7x57. Ive got three batches I’m working on, FC, RP, and mixed PPU S&B and Hornady. These are all range brass and shoulder measurements are all over the place. My 7x57 is borderline excessive headspace, so I’m sizing this brass to where it chambers but is not a true FL size. I’m thinking about necking it up and then back down in order to form a false shoulder, and fireform like you do with a wildcat. I may try 5 at first and see how they do.

I took my 12 year old and his friend and dad to the range last weekend and let them all have some fun, now I’m out of my 9mm, 45 Colt , and 357 levergun plinking ammo. Now I’ve got an excuse to fire up my new lee classic turret press. I’m excited for that.

Ive never heard them called a standardcat. Makes perfect sense though. That got a chuckle out of me.

I coined that just now .
It goes with the .270 dia 6.5 and the .318 7.7 and 7.62 .
An AI makes the case bigger , so does stretching the body ......
Mildcat fits too , I have a deliberate .007 neck up I use standard dies with the crimp step removed from the seater .

Out of all my 7x57 brass, the Hornady is the shortest at the shoulder. There are only 7 pieces, so I figured it would be the perfect starting point. I necked them up to 30 caliber, the started sizing them down to 7mm. After every small adjustment I checked for fit in the rifle. I finally got it to where there was some resistance closing the bolt but was not tight or hard to close. I’m hoping that after annealing and forming the false shoulder, I’ll be in business.

This is a great way of doing this! I have used this method often through the years in multiple circumstances. A little time consuming, but I always felt very confident in the results.

Just as a point to note. Today is a good day to be at the bench in SE PA, lol. A wet sloppy day all around.

Now I just need to settle on a load to use

Those are the best bench days. What will you be working on?

A little off the beaten path, but my bench also includes a 3d printer. I am setting up to print a component separating top for my Hornady powder drops. It is really a kind of sickness, this 3d printing thing, lol.
