I've got 66 primes for 15k=1019370495 and n<10000.
Does this imply that this 15k*2^n-1 is a prime-prone sequence?

At first glance it is. Could you provide me these numbers to be added to the stats, so I could plot the curve. n=10000 is low and large gaps can still appear. Some 15k`s have 3 types of curve others have gaps or stairs. keep at it at least to 50000 and then you`ll know.
