I load for 4 different 243's, all Remington 700's. I have found that W760 works very good in all of them. I've tried other powders, and IMR4350 and IMR4064 give good results, but overall 760 just works better. All of those rifles will shoot the 85 grain Sierra HPBT extremely well, and if I could use only one bullet, that would probably be it. But, I also use the 58 grain VMax, 65 grain Berger, 70 grain Sierra HP, 90 grain Nosler BT, and 95 grain SST's. For some reason, I can't get 100 grain bullets to shoot anywhere as consistently good as lighter weights shoot. I'm going to deer hunt this year with my 700 LVSF, using a 90 grain Nosler BT with 44.6 grains of 760. It's scary accurate.
