I did take along a small spiral note book, and a big black paper clip, to keep the wind from blowing it shut.
Every hit was logged, but was sometimes, the shooting was too hectic, to log in all the hits. I would use the 4 vertical lines with a slash , for every 5 hits , but when I would get a mound, with 2 adults, and a bunch of younger ones, I would shoot the 2 adults , and then pick off the young.
I got a couple of these a day, where I would get up to 16 hits on one mound, and one of these was early morning, calm winds, no mirage, and at 401 yards.
I was using 10 rd. magpul mags, as 20 rd mags get in the way bench shooting, as far as I am concerned.
I could not get the 2nd. mag in fast enough, and a couple would always escape.
We used 12X12 pop up tents, for shade, and the guy under the tent I was shooting from, was accusing me of spray, and pray, till I told him to look at the 400 yd. mound, and all he could say was, ''look at the carnage.''
He was using a Savage 22-250, single shot, and could not get off the kills I did.
I do not have a chronograph, so downloading a app. like shooter, requires velocity in the equasion.
I used a program, put out by a powder mfg. which only asks for bullet weight , gr. of powder, and barrel length.
With the .223 it was real close (within one inch.) , but the 308 was WAY off , ( up to 3 mil dots at 700 yards)
Most of the shooting we did, we had a (guessed ) 10 to 20 mph cross wind, and I was holding one full mil dot for windage.
Before next trip , I would also like to buy one of the hand held wind velocity gauges, and log that also, but the day I was trying the 400 to 100 yd shooting, I used 3 ft long steel rods, with 2 foot of surveyors tape on them for wind flags, and it could be absolutely calm at the bench, but the flag could be horizontal at 700, and straight at 1000.
So if I can watch the flags next to me sometime, and determine app. how many degrees the flag is flying at, and them measure velocity, I will have a better guess as how much to hold to allow for it.
This trip, it amounted to firing a shot, and see how far I was off, and compensate.
The great part of shooting out there was we could position ourselves in a''bowl'' ,and have 360 deg. shooting with safe backstops from the hills all around.
The only thing in the way, was the truck, and the poles on the tents.
