I'm preparing a load for hunting ibex in Kyrgyzstan in 3 weeks time. The 220SMK, 200SMK, 190SMK, are the pool of hevier bullets I have to choose from. I only have IMR4895, VV N160 and VVN560 to use as powders. I wasn't able to find much info on these weights for loads, so I'd like to hear what people have found works best out to the 800 yard mark. Can I get away with a 180gn bullet for these kinds of distances? Any advice would be appreaciated, tomorrow I will shoot the first batch of 220grainers and see if they prefer one specific powder, if the 220gn SMK's wont shoot then I'll start looking at the lighter choices. I'm running a Shilen select match grade barrel, 1:10 twist, so it should stabilize, 26" long on a trued Remington 700 action out of a Manners stock. Thanks.
