OK guys, I need some help. I have been shooting Hornaday 120 AMAX out of my 6.5 RPR (factory barrel, 1500 rounds). I have switched to factory Hornaday 140 ELD (they shoot great). My problem is that I have limited access to a 1000 yard range (4 hour drive) so I haven't been able to get there yet. My ballistic program (set at 29.5 baro, 80F, 60% humidity, 0 wind 500 ft elevation) calls for 8.6 Mils. No, I have not run the 140's through a chrono, but I did chronograph the factory Hornaday 120 AMAX and they came in about 8 FPS slower than the factory rated velocity (2910) with a SD of 10 FPS. My question is, does anyone have 1000 yard DOPE for factory Hornaday 140 ELD's? I know every gun is different, but what is the trend that you have seen? More than 8.6 or less? I have a competition coming up and could use real world data even though it is not my own. It is better than nothing at all. BTW, gun has a 100 yard zero and an APA brake. If you have MOA info please respond and I will convert it.
Thanks,
Bang
