What’s the barrel length??. The 139 Interlock flat base doesn’t take up much room in the case so you can fill it with your RL17. The Sierra Pro-Hunter would also be good. Both will work really well. Anything with decent BC will take up case capacity in your mag length and no real difference for the distance you mention. Sounds like you are very familiar with the 284 anyway.
I got up to 57gns of RE16 with the 139s in mine with a long OAL so safe for me but it fills the case so your RL17 will be better. W760 is also pretty good for case filling. Again in mine I got up to 55-56gns but not as fast as Reloader
Looks a cool rifle - will be interested how it goes so post your progress please
