Htr welcome to the forum. It appears as though you're on the right track with your Optima. I take it you're using the Cheap Shots to save a couple bucks (based on your post in the Traditional forum).
If you decide on a different bullet that isn't all that costly you can go with a Hornady XTP in either .429" or .451" and then purchase the appropriate sabot. I like the green Harvester CR sabot for the .429" or the black one for the .451". As for powder I'm having good luck with Alliant Black MZ powder. It burns clean and you can get it at Sportsman's Warehouse for $9.99 a pound. If you do use this powder it must be compressed tightly for best accuracy. I started using this powder last fall with a 300 grain XTP and so far I've taken 2 hogs and 2 deer and all but one deer was DRT.
