Take the time to read the article on (Ken Brucklacher 1000 yd score record).
Set at the Original 1000 yd benchrest club Williamsport PA. in 2009.
Read the article written on Accurate Shooter.Com.
Checkout how he prepared his cases for a new world record.
There is also a new member on this site, who is the only man (ever) to have won the year end aggregate award at Williamsport 2 times.
That award is given to the person having the best average group size for all the matches for the entire season.
He used a lefty Savage action by the way, and also never annealed a case in his entire life.
But I'm sure if these guys had access to the internet, their methods might have varied? lol
