Now that big game hunting is over, perhaps I'll have more time to develop some AI load.

Re: 270 Winchester build

WOO HOO...gotta love this!!

some argue that it's a 3 shot group...others argue that it's a 5 shot group....

so I decided to go with a 5 shot....

this is off of a bipod, and using my hand and an ammo box as a rear rest....

Range is 200 yards....

so, it's either 0.5MOA with 5 shots, or <0.25MOA with three shots....either way, it rocks!!

went to 700 yards with the 130 grain noslers...works real nice...was about 3" high.. my DOPE is a slight interpolation at the elevation and temp for the day...so not a big issue.

then stepped it out to 1000...used the 165gr Matrix VLDs...

wind was moving between 5 and 10 MPH, from 3 and 5 o'clock...really screwing with me...

first shot, 1 foot to the left...dialed in 0.5mill right..

next shot....1 foot right...

then felt the wind kick up...

stopped to let the wind die back down...

next three shots were all about 6" high, but all within the 1' center.

DOPE was reading 7.4 mills of elevation for the day.

Target is about 2000 feet in elevation, I was at about 1800 feet in elevation...temp was ~35 to 40F
