True big bore reloading

[15meter]

I was asked to look through a client's gun collection recently and it appears that he went through a love affair for big boomers. I know that some of you have extensive experience in this department - how different/ more difficult is it to reload for cartridges such as 577 NE, 600 NE, a whole slough of Jefferies cartridges...etc?
The biggest thing I reload is 50-90 - and that's in black powder!
Is it feasible to load these down for a more pleasant shooting experience? Does anyone cast for these? Is it possible to use a normal reloading press?
I must admit that I am intrigued by this collection!! And I'm sure at least one of my kids doesn't really NEED to go to college!
I'm sure this is going to be the first of many questions that I ask about this venture.
Thank you all in advance.

Curious, did you ever load any of the boomer stuff?

In re; downloading the big stuff, I have loaded for a .458 Lott to the levels of "hot" trap door level 400 grain boolits. What a joy to shoot. Retina detaching level loads no longer hold much entertainment for me. YMMV

I've done a lot of large caliber reloading, 400 Nitro Express, .416 Rigby and .458 WM. I have shot all 3 with full power loads, and don't particularly enjoy the recoil. All 3 of those calibers are in Ruger No. 1's, and all 3 are relatively light for caliber. RCBS Rock Chucker fits them all.

Loading way down with Trail Boss and cast boolits makes it a lot of fun, without the pain. Arthritic right shoulder determines current recoil tolerance.

I load for the 577 Snider. I use the standard RC press with the thread bushing removed.

I bought the Lyman Orange Crusher when I started loading for 3 1/4 cases.

The Lee classic cast works great for the 470NE
