I will be hunting deer with my new 243 this year, I do reload and I have on hand some Sierra game king 85 gr hpbt, and some speer hot-cor 90 gr spitzers. Would these bullets be sufficient, adequate, or very good? Should I go heavier? I will be hunting from a stand taking only broadside shots out to 200 yds. I have loaded and shot both of these bullets and I am getting 1.5" groups @ 200 yds.
