Does anyone know of a gunsmith that has done a lot of work on Model 99's ? The wife has one in 250. As with most of these rifles the chamber is a bit generous in size to say the least. The 99 ,with it's rear lockup, will always be a brass stretcher. Setting the barrel back a thread would help with brass life. Also ,since I have a custom 250 on order, it would help with reloading if both were headspaced correctly.
