[QUOTE="Jud96, post: 1794544, member: 69478"] I have tested and shot my .243 a lot with 87gr VMAXs. The best powders I’ve used so far are IMR 4350 and IMR 4451. I prefer the IMR 4451 because it’s temp stable. I shoot 44.3gr of 4451 for an average of 3370fps from a 26” barrel. Groups are very good, around 1/2” with a factory 700 Remington. I would start at 42.0gr and work up. My load is hot but doesn’t show ejector marks. I have also tested IMR 4831 and it was too slow. I started getting pressure around 45.0gr and velocity was 3300fps. Anything faster than IMR 4350 I don’t recommend. Max efficiency and performance will be achieved with any powder in the 4350 burn rate. RL16 and H4350 are both excellent powders, but i have not tested them in a .243 with 87s yet. For 95+ grain bullets I would use anything in the 4831 to H1000 burn rate range. [/QUOTE]
