I am looking for other loads for the 243 with some 62gr varmint grenades. Anyone used hornady superformance or varget??

I have tried several powders with the varmint grenades and sadly I have yet to find anything that shoots satisfactory in my Rem 700. They will not group under 1.75"-2" for 5 shot at 100yds. Shooting 100gr Sierra Game Kings I can shoot .75" 5 shot groups.

I have a few more loaded up with Varget and if these don't shoot I will abandon them. The same goes for the 75gr Hornady Vmax. I am not happy with them either. I just picked up some 55gr. ballistic tips to see how they work. Hopefully better than the other two.
