Sounds like the whole process was a great time. I live a couple hours East of Canadian where the real wind blows. We have the highest average sustained windspeed in North America, hey though when its windy its windy it don't really matter where. My father and I were shooting pdogs out in it last weekend and, like they say practice makes perfect, and I need more paractice.
We have shot targets out to 794 with some of the same loads in my 260 AI and I am wanting to move on out more in the ranges you were talking about. I enjoyed the article so much I forwarded the link to several of my shooting buddies. You are encouraging and inspiring us to reach farther, and by the way I am old enough to think the shooting mats are not a bad idea prone but its not so much the rocks as the stickers and cactus and ants and...
I look forward to more good info.
One real question, on your rear slide being parallel to the barrell, do you see that being an issue on shorter ranges too(500-800 m) or does that only come into play when you start reaching out to the mile? I pinch my rear bag and adjust it with my weak hand to settle for elevation and windage hold when I am shooting prairie dogs so when I move to the longer targets I had done basically the same while prone on the bipod. What I am wondering is, am I getting myself into a bad habit that way and not assuring a consitant slide in recoil? I use a slightly tapered stock shape that I could easily modify to straight but I wouldn't have the elevation adjustment you have on yours.
