Of the loads available in stores, does anybody have a recomendation for a brand I could use for Texas deer and hog hunting?

I preffer heavy bullets. Have just target shot with 240gr Mag Tech, 180 gr UMC and 200 gr Fiocchi. My rifle groups best with Mag Tech, but the first three boxs I bought required re-zero with each box change. There was not a change in the loads. Just differant boxes. I did not like that.
