If I could run numbers I wouldn't need books and the internet.Get a fast twist and run the numbers on a 131, 133, 134, 135, or 138 around 3200-3300 and then get back to us...
Speaking of the I-net, mine shows 115gr bullets sighted in at 200 yards with a MV of 3400fps drops about 48 inches at 400 yards. Is that about right or is the book wrong?
