I have this #7 shell holder; think it might be a Redding because of the knurl. It fits all my presses and various 275 Rigby / 7x57 brass including my latest batch of RWSI have issues resizing 275 Rigby brass (7x57) on the conventional presses (I’ve yet to find a shell holder that accommodates 7/57 brass - and have them all but none fit)

First , I should say I wanted one for many years and I have no experience with them . However, as with all Forester Products I am sure it is of excellent quality. The reason I don't have one is the over head leaver to actuate the press and the universal shell holder jaws.I am considering moving to a Co-ax press for reloading, are there any real world benefits?
Naturally the first instinct is Forster, but are there any major differences between that and the Frankford version?
i stopped using my RCBS hand primer for small cases for the same reason. I still use it for .308, but have a Frankford one for .223.The reason I don't have one is the over head leaver to actuate the press and the universal shell holder jaws.

I much prefer a shell holder to the universal jaws. In fairness I haven't tried the jaws but my experience with other things that have " universal" fit just hasn't been good.
The Turban 120mm is now selling at 810,00€ plus shipping here in Germany.I have had a Forster Co-Ax for about 14 years now. It’s a great powerful press and the jaws make producing ammunition very fast. I knock the completed round into a bin I position below the press. Although not too far below.
The arm is comfortable to lower l, I do have the short arm with ball. But the standard arm was just as comfortable and in hindsight the short arm really not needed.
However it’s situated in my detached garage. I tend to use my hand press for everything as currently I am not producing huge amounts of ammunition as target shooting has taken a back seat.
The $1 million dollar question being would I swap to a co-ax if I already had a large cast press. The answer is no.
Even the very basic Lee press I got in the anniversary set produced ammo goo enough for me to shoot in the .1’s all be it the rifle was a custom 6mmbr made by @Ronin but also consistently in the .3/.4 in a tikka T3 .308 factory rifle and my 7-08.
If I really wanted something fancy now I would be going for one of the Turbon presses. They just look like precision engineering where as the Co-Ax looks like cast iron junk from the last century![]()
I use the RCBS no 3 for 7x57 and no problems.I have four presses (Dillon, rcbs, harrel, k & m)
I have issues resizing 275 Rigby brass (7x57) on the conventional presses (I’ve yet to find a shell holder that accommodates 7/57 brass - and have them all but none fit)
I could resolve by buying arbour press dies from Wilson
Or simply get my friend with a Co Ax (Forster) to use my dies and re size
That’s a huge benefit to the Forster with the sliding jaw arrangement

That is an excellent article Laurie. That would be good reading for anybody looking at new presses.I'm a fan of the Co-Ax, so much so that I have two of them, one bought used on SD. (One has the universal shellholder jaws permanently switched to their 'small' (223 etc case-head diameter); the other turned to suit 0.473" - 0.550" case-heads. Quicker to swap presses than dismantling the shellholder and turning the sprung plates with the risk of losing the springs.)
Here's a comparative test I ran in 2015 using three makes of fired 7X57 cases on the Co-Ax, then new RCBS 'Summit' and current Rockchucker Supreme presses. Note all prices quoted are from 2015 and are a mite (!) higher now.
I was very taken with the Rockchucker for heavy duty full-length sizing, and can see why it's such a favourite even after so many years. For bullet seating, decapping, and sizing smaller cartridges especially if fired in tight chambers, the Co-Ax is a 'winner'. If like me, you load multiple cartridge models, the Co-Ax design is a huge plus with the universal shellholder and snap-in die holder. Throw in Forster's superb dies, especially with the Ultra Seater and its micrometer top if loading multiple bullet models, and very good results are the norm.
