I'm a new member, but I think I can offer a bit of knowledge here....
I've been reloading since 1973, have worn out a couple of firearms with reloads & should have been able to deduct Remington & Winchester a few times as dependants.
That said, here goes:
Current loading presses on my bench, left to right, calibers/tooling avaliable.
Lee 1000, dedicated to 9mm
Dillon SDB, 10MM & .45ACP
Dillon XL 650, 10MM, 40 S&W,(mm, 38 super, .44 Mag/Spl.
Dillon 1050, .45ACP, .44 AutoMag
Dillon 550, Rimmed revolver cals, varmint cals & CF rifle up to .375 H&H
I currently reload for a 4 man IPSC team; 9mm, 38 Super, .40 & 10MM, we just got to agree on something one of these days !
All of the presses I own have good/bad features, no one press is "perfect", not even the Dillon 1050. The new model, the Super 1050 might come close, as it can handle up to .30-06 & .45-70 size calibers, but won't do the real big stuff.
In a single station press, the Reddings are what I'd now chose over the RockChucker, but they wern't avaliable when I started loading.
I use my Co-Ax for case forming & heavy de-capping, it's stronger than the 'Chucker, not much, but it has a bit better leverage.
Sorry this is so long..I could keep going !
I'll try to answer any loading/press questions I can; My experience may as well keep someone from making the same mistakes I've made !
