i bought a .300 jarrett from kenny in 1989. he did the load development. it arrived with 1/2" targets at 100 yards with 200 grain nosler partition at 3005 fps and ballistic tip at 3350 fps (i never shot the bt, always stuck with the partition. Shot my first dall ram in the ruby mtns (yukon) at 450 yds, and then ate it when 911 stranded us in the back country for 2 weeks. shot a grizz off the horses to save us and them. Killed all my elk in the river-of-no-return wilderness in id. Never let me down. Seems to me all the .300 mag stuff/horserace really never has matched the .300 jarrett in efficiency and effectiveness. The jarrett never failed. Kenny, as you can see in the photo really grumped about putting that barrel band swivel on, and also providing an emergency peep (all sighted in of course at my insistence) in the butt cap. 5 below in the pic below. After 400 rounds in 20 years, reloaded with all the same brass (8 mm mag), still shoots 1/2 - but I put on a new swarovskii z5 with ballistic turret, typed kenny's load into the swarvoski ballistic calculator, and am hitting the gongs out to 700 yards at the white sulphur springs range. So I get it about hot rod rounds and their inconvenience, but I went through so many failures with off the shelf rifles, that when kenny told me at sci that he would guarantee the rifle's accuracy (this was in the day when that was unheard of - and believe me I at that time was over the "ohh ittle shoot -" I was sold.
obtw, wayne at AHR just recently went through the jarrett drill for me and delivered this .404
