thanks for the info. I have been looking all over the internet, trying to find some loads for the 243 with the imr 4350, but i'm not having much luck. I am going to try that load to start, and if i can't find what i like , then i may change to a different powder and go with the 58 gr. vmax. If any body has a good suggestion for a long range varmint load with the vmax bullets, i would like to hear them.
