G'day! I was hoping any of you guys could me tune my 22lr. I have a Fieldman Naughton which is Australian made and very similar to a Ruger bolt-action. The trigger has adjustment for creep and pressure which i have altered both but I would still like to wringe a little more out of it if i could. The gun itself has a 161/2 inch barrel made of aluminium with a steel sleeve. the barrel is of the same size as most varmint barrels if not a little thicker so i can only think of bedding?,or something similar. Any help would be appreciated!
