Need Info on RL450

I'm an avid user of the Square Deal B for my pistol reloads and now wanting to go progressive with rifle ammo. I know the Rl450 hasn't been made in 30 yrs. but I have a few questions.

1) What is the largest rifle caliber that can be reloaded on the 450? I want to be able to reload .223, 300 AAC, .308 and 7.62x39.

1a) Ram length? Ram diameter? Solid or hollow?

2) Has any bullet measurements been taken of a reloaded 450 vs. 550 as to concentricity runout, OAL, etc? I've read the Redding T-7 is highly precise but watching videos I see a small amount of deflection in the turret while seating / crimping (which bothers me) which is why I want to stick with a closed frame Dillon 450.

3) Can someone provide me some additional specs or a manual?

Thank you.

RE: Need Info on RL450

The RL450 is the predecessor to the RL550B machine. They use the same caliber conversion kits, and the rams are the same. You can load up to a Remington Ultra mag, 416 Rigby, or 378 Weatherby-based cartridge on it.
No idea on the length, but the ram is solid steel.
Because of the floating toolhead on the RL550B, if you set up your dies correctly, runout can be less than is on the RL450.
The primer feed and powder measure on the RL450 were manually operated, however the current automatic primer feed and powder system of the RL550B will readily attach to the RL450.

You can do upgrade a 450 to almost everything a 550 does except the quick change toolhead.

RE: Need Info on RL450

I just stumbled on this thread. I bought a 450 new back in the 80's and it was all I used until a few years ago when I bought a 550.

I set the 450 up for .308 and it works superbly for that! I agree with the above post in that there is a tighter tolerance with the fixed head of the 450.

I have loaded a LOT of ammo on this 450 and other than occasional clean and lube there have been NO issues with it. I'm keeping it!
