The "bargain" x39 rounds likely won't give you the accuracy you would desire in a 10" contender, or any other gun for that matter.

For supersonic go 7.62x39 if you are ever gonna use a suppressor go 300blk.

From a 10-inch barrel I am not sure your going to actually be able to fully take advantage of the extra case capacity of the 7.62x39. You don't need the capacity for fast powder and you don't have the barrel length to burn the slow powders.
300 BO has such a well developed and broad selection of bullets for super or sub sonic. A 10-inch barrel works very well with many 300 BO loads.
Unless cheap factory ammo is you prime selection criteria I think I would lean towards 300 BO.
A potential middle ground especially if you are sure you not going to play with sub-sonic then maybe look at 300 Ham'r. You can still make cases from 223/556 and you will get better super sonic performance out of it with good .308 bullet selection. Still does not have the case capacity of 7.62x39.

In actions other than semi-auto, 7.62x39 can achieve very good accuracy, if you handload. A 14" would be a better choice in 7.62x39. If you absolutely must get a 10", the .300 BLK might serve you better.

Umm steal case can be very accurate, I'd get the 7.62x39 be nice to try some subsonic loads.

It's a single shot pistol. We don't know purpose. We don't know if there is ammo commonality with other guns the OP owns. For the Encore pistol, use or application (by whatever criteria the OP deems fit) should outweigh ammo cost. Simply holding the pistol steady and the load unload process gets tedious and un-fun within 50 shots per range trip, especially with cartridges that may recoil harder in an Encore vs a rifle or "braced" pistol.
Single shot pistols and rifles extract better with rimmed cartridges. If you have a hot load or dirty chamber, the brass can stick and the extractor can jump the extractor groove in rimless cases after a cartridge is fired, requiring a cleaning rod to physically knock the fired case out.
x39 and BO are too ballistically similar out of a 10" tube to pick based only on muzzle velocity. Application and caliber commonality are the keys to choice. If the OP reloads at all and doesn't care as much about subsonic loads, the 357mag or 357max is hard to beat in a single shot. It's not like you need the extra BC from the .308/.310 bullets for a 10" barrel.
The fact is that we need more information from the OP to further discuss, outside of the only discussion point of cost.

Quick answer: I vote 7.62x39
Medium answer: 300 BLK shines in the AR platform, but if you're doing anything else, x39 would be my vote whether it be AK, bolt gun, single shot, cheap ammo, expensive ammo, handloading....
But that's just an opinion

I have an mgm barrel being built for me as I type in 300blk for subsonics only.
Im a big fan of 300blk, and think, if you reload, its a better choice due to the plethora or bullet choices.

As noted, it depends on what one wants to get out of it.
I bought an SSK .300 Whisper barrel for my Contender several years before Rem/AAC rebranded it as the 300BLK. At the time, factory ammo was available from Corbon, but they only loaded it in batches, usually several years apart. I think I still have a couple boxes somewhere.
But I bought it intending to reload, and to shoot subsonic/suppressed. Some other cartridge having a velocity advantage doesn’t mean much if you only intend to top out around 1000 fps. For me, there was a better selection of .308 cal bullets from 60 gr. up to 240 gr.
I suppose I could have had a .308x39 barrel made and done the same thing. Ruger’s Mini-30 reportedly has a .308 barrel and still shoots .311 surplus ammo ok.
But that’s what worked for my. Someone else might find the x39 works better for them.
