Sorry if this is not the proper section, but I have a TON of 30-06 brass so I am formimg 7x57 brass from it.
So here is my question. What is the quickest was to trim (cut) the neck length down. I was think of making a jig similar to an arrow cutting jig.
Any ideas?

Trim die and a hacksaw.

I used a hacksaw blade and left my cases a little long then stuck them in my case trimer.

Put a power drill on a normal case trimer makes short work as well.

Trim to final length I&O diameter chamfer and possibly neck turn, depending on the brass manufacturer and chamber tightness. Some where in there annealing might be a plus. roger

I have made a lot of 7X57 from 30-06 with a Redding trim die and a hacksaw.

I'm sorry you felt it necessary to take exception to my answer. The question was how to quickly trim the brass not what was needed to form it.

I saw a minature chop saw that somebody was shortening cases with. Don't remember where.

THANKS - that is exactly what I am looking for!!!!

I have done it by making a jig and running off the extra length on a linisher. Simply a block of hardwood with apropriate holes drilled with the shoulder dictating length of exposed neck. A quick push against the linisher with a course belt has it done then a finish trim in case trimmer. Done 30-06 to 7x57 and 223 and 222 down to 221.

This is what I use, its a been a life-saver, and so much cleaner.

This is not what you asked, but I'll throw it in here anyway.

I trim my semi-finished "7x57 from .30x63" ('06) brass (usually with a 32 tooth hacksaw and a file/trim die (followed by an electric-powered Wilson trimmer) if I want a length shorter than what just the trim die provides.

Then I neck ream it to make sure the neck is uniform thickness for its full length and has no "donut" from sizing down the brass at the base of the neck/top of the shoulder of the parent '06 brass.

Then I do my chamfering.

That isn't all necessary in most chambers, but as I have this 50+-year-old old RCBS 7x57 neck ream die, I sometimes do it anyway. Doesn't seem to hurt anything, and I only have to do it once, so if I have the time and am in the mood, I do it.

and then there were those that had a good ideal, they chambered their 7mm57 chambers to 280 Remington, then went to the range and road tested their new creation only to find the 280 Remington reamer did not clean up (remove all) the old chamber.

most got over it or got used to to it, not the same person with the 7mm57 but others with 308 W chambers that wanted a 30/06 chamber, they went to the range and discovered part of the old 308 chamber at the shoulder left a ring around the case after firing, that left them with a few choices, 30/06 Ackley Improved or 30 Gibbs to mention a few, the few I know got over it and continued shooting, I thought it was handy when determining brass stretch and or flow, the ring around the case served the same purpose as a skid mark, if that is what brass does.

I use the trim/form die with the hack saw then file, I also use the aircraft countersink, avoid hitting the die, once the case is flared, lower the ram and the excess neck pops off.

When I make 30 Herrett cases from 30/30 brass there's alot of trimming to be done. I make the first rough cut with a fiber reinforced cutting wheel on a Dremel tool. I then deburr the case mouth and finish up with my case trimmer. Make sure you make the rough cut long, since it will be anything but square. Your case trimmer will square things up.

that's me -- made a "tail stock" with a piece of L shaped delrin (walnut will work fine) and a screw to set depth ...

note: this is DANGEROUS in operation.. high speed saw, brass, fingers, blood, ER, BE CAREFUL

went from minutes per case to a couple seconds.
