I just recently bought a Remington 700 sps Varmint 243. win with a 26" bull barrel, im going out to pick up a Vortex Viper 6.5-20x44mm tonight i believe and im hoping to get some load work done this week and test it out this weekend. This guns primary use is for coyotes, targets out to 500-600 yards, ground hogs and crows. But mainly coyotes. I was thinking of running the 75 grain V-Max or the 87 Grain V-Max. Which do you suggest for coyotes at ranges 400 yards and closer. I will test both out to see which gives better accuracy but in terms of better bullet for the job, which do you suggest? I also dont know which powders to use? I have the H4895, H380, RL-22 and RL-17. I think the H380 and the RL-22 might show the best results?
