Not at all needed for "power". But is it a wild hair, to use a mini arbor press ta seat gas checks square & even?

A fellow in Portland Oregon made a tool to do this 20 plus years ago.it didn't work any better than using the gas check seater "stop" in lubrasizers.in a reloading book from the 50s they show tapping the bullet with a wood stick to seat the checks!

I devised a "swing-a-way" plate for the Lyman 45, for use as a GC seater.
The Lyman factory GC seater thingy does work better than a plate (like I made), but the factor thingy doesn't work on the 45 :(

Worked on a 44 seating gas checks

I wasn't talking about 45 caliber bullets, I was talking about a Lyman 45 lubesizer.

Could you trap the Lead bullet in a collet puller and fashion a flat "cap" to place over a reloaders Ram and get square that way?

I have a couple Lube sizers.
I have used a 1/8" thick small piece of steel and "pressed" checks on. It works. Might be cheaper and just as good if I weld a "peg" to fit in where sizer would go...

I also have the NOE sizer kit with the gas check seater. It uses a shell adaptor with a hole to use top Punches upside down with a flat plate to push and seat. Kinda what gave me the idea.
I have wanted a small arbor press for a while any how. Aughta be easy to make a adaptor for a top punch and use it easier then the reloading press..... Just kinda thinkin alowd. Now I seat with fingers and tap tap on mount to seat. 98% it works fine but fatigue is becoming a issue with arthritic hands. That small amount that dont seat right would be beneficial with the press/arbor.

how's about a top punch in a small arbor press.

I just press them into place similar to how Jon does it, only I use a star sizer and a flat plate of metal instead of a 450.
I guess if I wanted to make 100% sure I was ''straight'' I'd use some sort of blind die with a top punch to get them back out again.
but then again I could just push the core into a copper wrapper in one of those and not worry about it so much.

That was my thought. Change the bottom star plate with a 2" sq of 3/8" plate with a hole to take a top punch.

But thinking thru, I too have used a scrap of 1/8" steel on top of the sizer in my 450 to seat an occasional stubborn check. Maybe I just make up a "plate" with a peg on the bottom to center on the 450. Maybe something useful for others too. Should be easy peasy even outta scrap at my shop.

An aircraft rivet squeezer works very well until the bullets are to long to fit in the jaw .

A guy with a lathe would have no difficulties in making a couple of generic nose punch rams for such a tool .

It works fine on mine.

The gas check seater works on my 45, too.

Ian,
My 4500's instruction/parts list shows the seater installed the other way round, and that's how I use it.
Is there a particular reason why you install it that way?
Obviously, it prevents the ejection rod from moving, but don't you want the rod to move a wee bit to eject the bullet?

You do want the ejector to move a wee bit and it does. A Hornady check gets about halfway crimped with my setup (tapered H-die entrance) and requires the ejector rod to pop the bullet back out without tearing the check off. The reason for turning the seating stop the wrong way is that it will mushroom the threads on the adjustment thimble if turned the way you would use it on the 450/4500.

Okie, dokie. I removed the 45 from the bench, but if I ever re-mount it, it won't be used for seating gas checks.

I use the Lyman check seater thingy AND flare the Hornady checks with the NOE flaring tools to "take up slack" between fat shanks on Lyman bullets and too-square form on Hornady checks. This seems especially prevalent on 30 and 35 caliber Lyman moulds. Checks seat squarely, and life improves. My more recent mould acquisitions are not of gas check design, though. Funny how that happens.

I'll have to thoroughly re-look into this, as I never tried the insert upside down.
BUT, in the meantime, even though I don't have a 45 mounted to the bench right now, I grabbed one this morning and put the GC insert in there, it didn't want to fit, but I wiggled on it for a while and it finally slide in. There was no moving the "I" part of the die with the insert in place. I bet there is some simple mod I can do, to make a little movement?

I just checked and it will go on either way but to keep it from falling off I put it on upside down and rotate it 180⁰ so it doesn't fall off. Loosen the hollow adjuster screw to let the seating stop fall down and give the ejector about 1/16" of vertical movement.
