Re: 6.5 140 Hornady SST
Not the best of days to be shooting but what the hell, better than sitting in front of the t.v.
Started out with the 139's. Had a 10-15mph head wind again from 12:00-12:30. I didn't set the Chrony out to check velocity because the wind was suppose to pick up somethin fierce. But from the last couple of times of chronographing them it has been pretty consistant at 2790fps 14ft from muzzle.
I got my 100 yard zero and proceded to check my drops.
By the time i was ready to shoot and check the 1000 yard drop the wind had started to shift to 1:00 but to shoot the 1000 yard i have to turn slightly to my left which makes the wind coming from 2:00-2:30 at 10-15.
Cleaned the gun up for shooting the 140's(sst'S) and after getting a 100 yard zero the forcasters were right today , for once.
The wind had picked up to 25-30mph from 12:00-12:30
The wind was blowing hard and i was shooting by myself and didn't think i wanted to try 1000 and try and spot my hits.
The last loads i had for the 140's were clocked at 2762 at 14ft from the muzzle. I bumped up the charge by a .5grain today. Didn't chrony these either but i am sure this load is close to 2790.
First time doing load work up with these i had a 1.5gr spread at 100 that all three were acceptable so i picked one.
I also shot 4-5 rounds at each distace once i got to the center. Each group averaged 1-1.5 moa out to 1000 and 660(140's). I wish I had saved some 139's to test in the heftier wind to compare but i didn't.
Seems like the calm days are in the middle of the week when it knows i can't get away but i might have to play hookie one of these days to really see what the differance between these two bullets are but i still believe the 140's have a b.c. of .6 or higher. It is not the advertised .5 that hornady says.
I am also thinking of checking the 140's for consistancy to see how they are. They can't be any worse than the sierra's
