When can you plant in Dustin, OK?

Zone 7b

Around 03/24 is the usual last spring frost, about 208 days away. The first fall frost typically arrives around 11/09, about 229 frost-free days later.

Dustin sits in USDA Zone 7b (5 to 10°F average annual minimum). The dates above are NOAA's 1991-2020 normal at the nearest reporting station, a 30-year average, not a forecast.

How much risk comes with planting early here

03/24 is the middle of 30 years of NOAA records, not a promise. Plant by 03/05 and you're betting against frost in roughly 9 years out of 10. 04/10 is the safer bet, historically only a 1-in-10 chance of frost that late.
