All lead bullets.. you could try some Buffalo Bullet SSB's if you can find them in 375 grain. 405 grain powerbelts are not too much for deer. I shoot a 500 grain all lead conical with 70 grains of powder. I will plant that deer where it stands. You could also try some T/C Cheap shots. Load about 80 grains of powder and try them. They are all lead and they are a good deer load. Put them in the right spot, and they will get the job done, I have read.
