I'm shooting a 65 mm (2 1/2) chambered 16. RSTs retail at LL Bean's (closest store that carries them) for $11.95 a box. By way of comparison, regular retail on 2 3/4 Remmmie Express goes about $14. And specialty 16 ga loads are rarely under $10.
The RSTs will kill your game or targets just as dead and at a lower pressure. Ask the phez I shot earlier this week - dead from an RST before it hit the ground.
You're only going to save some money if you reload - you can cook up a box of any kind of load for $6 or less. But if you reload, you can cook up an appropriate load for your gun that will not require cutting metal. If you want low pressure loads, there's a whole group over at 16ga.com (the 16 ga society) devoted to developing and pressure testing low pressure loads for 16 ga guns. They have something like 1000 or 1100 different loads on file.
