Finally the cattle are out of the pasture and i can tend to shooting my 338 Lapua. Went out last weekend to get some yardages with my GPS to see how far i can get. I can get 1 mile(+,-). With my setup for my rifle i am 19" high at 100yards. Ran the numbers in Sierra Infinity and came up with about 850yard zero. I had a chance yesterday to load a few rounds with charges and shoot through the chrony to get some speeds and see how hot i can go before to much pressure. There is a tall rock formation at 1400yards(+,-) that i set up on. Ran some numbers for 300gr. bullet at 2850(as that is my target goal), cranked in 22min. of elevation and 2min. of left. Zero wind. I haven't had these kind of conditions in a LONNNNGGGG time.
So my question is ...
I was roughly .5mil down from point of aim and 1 mil right.
I have a nightforce 8x32x56 NXS. I was shooting on 16x
For correct mil ranging it should be on 32x.
For 16x 1 mil equals (roughly) 7.2" at 100. So at 1400 yards it is 100.8"(roughly)
1moa at 100yards is 1.047" and at 1400yards it is 14.658"
So on my rough calculations i should dial in 3.5moa up and 6.8moa left. Am i doing the math right?
We are suppose to have another day like today tomorrow. 40 degrees no wind and sun shinin. I am going to load 5 rounds of each charge that are safe and shoot at my steel target at 1400 yards. I know, why are you testing at 1400 and not closer? Well i haven't had days like these and i want to take advantage of them and see how they shoot way out there and then i can fine tune the load tomorrow to try and tighten the group up while i have the conditions good. Hopefully i can remember to take my (crappy) digital camera along and photo each group so i can post them to have you guys give me your input.
This will be the first attempt at 1400yards and my target is 4'x4'. With conditions like they are i hope i can find a load that will do 2moa or less. I think if i can find a load that will do that i will be tickled and can look forward to shooting more and fine tuning it.
I haven't had the time to work with this gun like my Rem. 260. So now that hunting season is over i am devoting my time to the Lapua and finding the load. I already know my load for the 260 and might try to shoot it to 1400yards and see what it does in these conditions.
Thanks
Matt
