Day at the Range
Wed. was a cold blustery day in Central PA. We were set up in a field trying to ring some steel. It was about 21 degrees with a head on of 10-15mph winds at the bench and 8-10 with 10-15mph gusts left to right at the target. It took me about 15 shots to walk it in to the steel. 22.25MOA up and 6.5MOA to the left put me on and was able to ring it consistently with my little 18" custom. I was using 48grns RL17 with a velocity avg. of 2612fps. They were up and down with about a 30fps spread. It was very difficult to figure out the right wind velocity at the target.
When it was warmer the spread is more like 15 to 20 fps. The RL17 is very temp sensitive. Anyway with those click values put us at a LRF distance of 695 yards +/- 5 due to conditions. We had some empty helium tanks that we hit right around 705 to 710yrds. I could really tell the speed variance at this distance. Some would drop short, some over, and a few dead on the target. All in all, this was the most successful shooting outing I have had to date with a .308 at long range. I do have a couple of hits at 1060, but that was with my 300WSM and it was not consistent at all.
My cousin with his Lapua had hits all day long. He only missed when aiming at the Helium tanks. Well at least we thought we had missed. The were passing through the back of the tank and thought we were shooting high. Oh well, lessons learned.
