May 1997 issue of Precision Shooting, in an ad for Krieger Barrels, Inc. that showed an actual-size copy of a 20-shot group shot at 800 yards by Bart Bobbitt with his Krieger Barrelled PALMA rifle." Now this group has a .942" mean radius, with an extreme spread of 3.325".
On May 10, 1997 on a usenet gun forum, rec.guns, Bart explained, "I used a .308 Win. with Sierra's 155-gr. Palma bullet with 45.3gr. of IMR4895 and RWS Primers in full-length sized WCC60 match cases. Had a 20X scope on the English Paramount action and shot prone with a bag under my front hand to steady the rifle. It was about 6AM in dead-calm wind conditions.
A painting of a picture of Bart is the NRA icon for accuracy.
Bart says that David Tubb is the best person at wind doping he has ever seen.
--------------------------------
I have a 308 reamer, more than my weight in 308 brass, and a dozen 308 rifles.
I have never had the accuracy with a 308 that would have me shooting at deer beyond 400 yards.
But with a 7mmRM loaded hot [not BS 7mmRM published loads] I can hunt out to 500 yards.
I am not a Bobbitt nor a Tubb, so I need every advantage I can get, so I do not hunt with a .308.
And since May 10, 1997, I have tried to shoot on low wind days.
