Mine is a commercial mauser 98 (Husqvarna) .243 purchased in 1958. My dad used it in Shutzen events off and on for some years eventually replacing it with a Sako. When I got it I initially accepted its accuracy problems (thrown 6th round) as a limitation but about ten years ago I decided to work with it. It had an adjustable trigger and a terrible set of rings on it. I carefully cleaned and lapped the bore then cast it to take a look at the chamber throat. I knew that the rifle had always been cleaned from the breach so I was not worried about the crown. After determining that the chamber was not eroded I used a Sinclair OAL guage to find the absolute length of the chamber and noted it for load development. Using Sierra blitzkings the rifle almost immediately became a one hole shooter. The rifle likes Varget and Hornady ballistic tips most with one ragged hole in the eye of a CQB target at 100 yards. I am able to hit the UPC code on water filled plastic bottles at 300 yards all day long with this rifle. Now the rest of the story is that this rifle is a sporter weight barrel, the original. It outshoots my custom 22-250 with its bull barrel. My go to gun for coyotes.
