FWIW,that press is held in high regard by people who pursue extreme accuracy.Its known for producing concentric,straight ammo.
It will work very well with Forster dies,which are designed a bit different,and also produce straight ammo.
Once the lock ring on your die is set,the die just loads in the recess.No screwing it in. You have a universal shellholder. Up at the prime station,too.
Even if you buy a Dillon 1050,its always good to have a single stage press on the bench.Thats a Cadillac press,something (generally) advanced loaders step up to.
I suggest you try loading with it for a year or so before you make the decision to sell it.
If I may ask,if you sold it and had the $,what press do you imagine you would rather have?
I like having two single stage presses on my bench. You could have a size and prime press,a powder measure,and then a seating press. They can be mounted so you can run all of them from one stool.
If you have several loading blocks,two guys can safely "tag team" two presses and make some production.
One guy can be pulling brass out of polishing media while the other trims and chamfers .
Followng that,media guy switches to lubing,trim guy starts sizing/priming to a block of 50.
Lube guy moves to powder measure.Pulls uncharged brass from his left,charges,puts in a loading block on his right. When that block is full,powder level is visually checked under a good light.
At some point,all the brass is sized/primed. That guy moves to seating.
Powder charge guy moves to wiping,inspecting,boxing.
I've had my Thumbler's Tumbler a long time.Its older than some here. It still works fine.
