This is a question beyond my pay grade but can take an educated guess.
I would have thought you needed less powder, as the longer barrel gives more time for the burn to propel the bullet through the barrel.
Someone above said Unique 5gn - which is close to the max in the Hornady table (at a 4" barrel). Perhaps start at the low end of the table (600fps) which is 3.9gn of Unique, and chrono it. Does your range have a max energy requirement? Do the maths - and see where you need to be fps wise. Every gun is different - so you will need to make some test loads and find what works best for you. This published Hornady data is tested - so it is a good starting point no matter what powder you use.
Also - please do get a consensus from other shooters before trying any load rather than relying on a single rando like myself. While I do understand the principles behind it - i'm still no expert.
I'd be interested to know how you get on as i'm getting a 38/357 under lever sometime soon. Personally i'm going to be using N340 once I start reloading this calibre. I've pretty much stuck with Vhit powders for all my reloading as it is "European" and i'm confident will be available in the future
I use red dot for both taurus and Henry rifle, use 158gn for the rifle and 148gn wc for pistol.
Would advise to use 357mag cases rather than 38sp. So you don't get carbon build up in the Chambers.
Pm me if u want recipes. Red dot quite easy to get in gunshops.

Crosman Rabbitstopper- .22, Chinese XS36-1- .22
Have a look at a powder burnrate chart to see what is close to N310 etc.
Have a look at Ramshot and Lovex powders.
Vectan BA10 or AS are great for 38 special if you can find some
