Hello again! Does your JCH need a Timney??? Mine was worked on ages ago by a smith when my dad had it, it is much better than my Timneys on other guns. You would be looking for a Timney for an FN Mauser, go on line to Brownells website and you'll find one, but wonder if a good smith can do you right and save you the trouble maybe?
Welcome to the JCH club. Funny, people tend to sniff at these because they say "Sears" on the side, but these are some of the finest rifles ever produced. FN actions, High Standard barrels, I put mine in a McMillan stock..stuck a leupold on it 20 years back and it shoots MOA groups all day with Hornaday Light Magnum .30-06 150 gr Interlock.
Again, congrats on a fine rifle!
