Calculator burn assumption
0.60 lb/hr at 225 F. Planning number only. Not a lab test.

Hopper hours and pellets per cook

A 12 lb brisket at 225 F plans at about 16 hr 30 min, but in winter a full 15 lb hopper runs only about 11 hr 38 min, so an overnight brisket needs a refill around hour 11. In mild weather the same cook uses about 10.3 lb and finishes with about 4.8 lb left.

How long a full 15 lb hopper runs on the Recteq RT-B380 Bullseye, after the 0.35 lb startup pad. Burn starts at the 0.60 lb/hr assumption at 225 F and scales with set point and weather, the same math as the calculator.
Set pointMild (about 60 to 80 F)Winter / sub-freezing
225 F24 hr 25 min at 0.60 lb/hr11 hr 38 min at 1.26 lb/hr
250 F21 hr 31 min at 0.68 lb/hr10 hr 15 min at 1.43 lb/hr
275 F19 hr 11 min at 0.76 lb/hr9 hr 8 min at 1.60 lb/hr

Same 15 lb hopper elsewhere in our database: the Pit Boss Lexington 500 (about 19 hr 32 min), counting a full hopper at 225 F in mild weather on that grill's own assumed burn rate.

Pounds of pellets for two common cooks on the Recteq RT-B380 Bullseye, startup pad included. Cook time is the calculator's planning estimate for the meat and set point.
CookPlanned timeMild (about 60 to 80 F)Winter / sub-freezing
12 lb brisket at 225 F16 hr 30 min10.3 lb21.1 lb (more than a full hopper)
8 lb pork butt at 250 F10 hr 42 min7.6 lb15.6 lb (more than a full hopper)

Those pounds include the startup pad and assume a full hopper at the start. For how meat, set point, and bag size change the total, see how many pounds of pellets a smoke really takes.

Each pellet figure opens that cook in the calculator with the Recteq RT-B380 Bullseye already picked, or run the winter brisket for this grill in the calculator and change the weight, temp, or weather yourself. Wind, wet pellets, and a leaky lid are not in the math, and they usually burn more.

Notes

Small grate, 15 lb hopper. Pellet math is friendly. Rack space is not.

PelletDeck did not run this grill in a lab. The burn assumption exists so the calculator has a starting point. Override hopper size if your unit differs.
