Is this referred to as timing? Is there a way a novice can adjust?
Timney for quite some time made triggers with sears that effectively shortened pin fall by .050”. They did it to give a nice smooth bolt close. What it really did was cause a ton of failure to fire issues because of too little pin fall. Surgeon actions with these triggers were the worst. It was so bad that Timney offered a “long” sear for a Surgeon. Anybody that knew any better would request the long sear to start with for any Remington or Remington clone. There were other issues with the earlier Timney’s that could be fixed but after awhile there were better options. Timney finally saw the light and quit chasing the short sear, easy bolt close thing. If this is what is going on I’d learn to live with the harder bolt close of the Shilen.
It may be a cocking piece/sear height binding issue with the Shilen. BnA on several triggers offers three different sear heights to work with various actions. You might head over to Bullet Central’s website and take a look at the chart. Measure your cocking piece height and see where it stands. They have videos showing and explaining how to do it.
