What subsonic straight wall cartridge for whitetail? Not 45-70 or crossbow

[Bluefish]

Sounds like what I'm after, is there a name for this cartridge?

I have an an encore and enjoy it so it would be ok to get a new barrel for it. A friend has a 357 max barrel for encore and has used it successfully for whitetail

I have a couple .475 Linebaugh, which is a 45-70 case shortened to 1.4" Due to the taper of the 45-70 case the inside dimension at that point fits a .475 bullet.

I would use maker expanding copper subs 400 or 500g in the 45-70. The bullets are so long that a shorter case should have no real effect. Could probably just cut down brass and use in a regular 45-70 chamber. Note Hornady already does this a little for the ftx bullets. Brass is shorter so they can keep the 2.55 oal.

For encore I would look at the 360 buckhammer. Although due to twist you are limited to just over 200g bullets.

I just discovered Maker's has subsonic all copper ammo in 450 Bushmaster and 350 Legend.

425 gr 350gr, 250gr for 450 Bushmaster, and 220 gr for the 35 Legend.

I've got a 350 legend and a .357 mag that both may fit your needs. Thinking about going suppressed but haven't gotten there yet. The 357 mag is a deer killer with fast XTP bullets, no idea how well it would do suppressed with heavy bullets. 350 Legend is okay, the 357 mag impresses me more.

I've used 357 mag 158gr XTP with max load of H110 out of a 6" revolver with success. Not sure of the velocity as it was before I owned a chronograph.
