Shakari:
Assuming 2150 fps at the muzzle, and sights filed in for 60 yds, the 570gr Woodleigh RNSP is an inch low at 100 yds, 4 inches low at 150 yds, and about 9 or 10 inches low at 200 yds.

If you were to sight it on the money at 100 yds, the mid-range trajectory would be less than an inch high, and only down 2 1/2 inches at 150 yds, and 7 or 8 inches low at 200 yds.

How does that compare? Good enough I'd reckon!

Get yourself a copy of Point-blank, a free-ware ballistics program which is invaluable for this kind of mucking about.
Download it from here:

BTW, I can supply the Woodleigh bullet data for Point-blank's bullet database, if anyone is interested. E-mail me at marrakai577@hotmail.com
