Drift?

Wow! What a cool word for improper beeding.

I am sure it occurs for some rifles. You must know where Mechanical Zero is for your rifle at a particular distance.

last time at 1000

My F-T/R rifle "lives" w/ a 600 yd zero and I lob 175/.30 at about the speed you mention. My 600 yd zero is +15MOA at 100, which I can check pretty easy at the nearby state range or even in my neighbors hayfield.

Last time I went to 1000, I put +23MOA (+38 at 100) on the rifle, which is what my log book called for, and shot my first sighter. My spotter advised to come down 1 MOA, which I did, (for +22, +37 from 100) and shot again. An "X" ! Man, I thought it was my day, two sighters and in the X ring!

I never shot another darn x the whole day, 40 rds for record (two relays) and a good handfull of sighters the second time up. Some times I just wanna quit.

But yeah........I think you get the wind right, or close,and a good squeeze, and you should be on paper with +40MOA up at 100. Maybe a tad high.

Could not follow.

I need an additional apprx. 25 moa adjustments, up, from my 600 yard zero to my 1,000 yard zero depending on ambient temperatures.

Where I come from we don't get sighters.

Get yourself a Rav-Vin micrometer.

These are close copies of the P.J. O'Hare, which are very collectable.

I have both, my Ray-Vin is tighter

There is no way you are going to make any sort of decent elevation adjustments, particularly at 1000 yards with an 03 without this micrometer.

A 1000 yard target frame is supposed to be about 8 feet by 8 feet, but in actual practice it is about 8 inches by 8 inches. You don’t have to be off my much to miss the darn thing.

If the sticker shock hits you, just wait when they go out of production. I have not seen new P. J. O’Hare micrometers since the 60’s. And I don’t think they were made past the 40’s.

sorry

Sorry for confusion

100 yds- minus 15 moa
600 yds- 0
1000yd- plus 23moa (22 in the conditions on day in story)

Total of 37-38 up from 100, to get on at 1000

I'm punching paper, guess your not
