I appreciate your opinion, but there are guys who see it just the opposite way. What disadvantage do you see in timney?
They all work and have worked on many many rifles over several decades of use.
ALL have been used as OEM triggers for custom rifle brands in the US.
Chevy, Ford, Dodge debate.
Where the Jewell shines and gets the most press is in the competition application where super light trigger pulls are desired. They work very well in the 1 to 3 oz range.
And yes, a blown primer can send them packing. But then competition shooters tend to be very careful loaders and strive for 100% operational reliability.
Shilen is also very good in this regard but not quite as crisp as the Jewell. At 2oz, there really isn't much creep no matter what brand you choose. For hunting applications, they need to use the safety and bolt release from the orig Rem trigger group. Not so easy now that the Promark triggers aren't easy to strip parts off (don't even think the parts fit at any rate).
These were listed as OEM for Surgeon Rifles in an article I read a little while back so are well regarded.
Timney has served the rifle industry for a very very long time and might just be the oldest of these three. They work, are robust and easy to set up. Their market is not the competition shooter so their options and operations are limited in this regard.
For the average shooter wanting a 2lbs pull, all brands will work. Even a tuned factory trigger will do just fine.
But when you measure pull in ounces, there is a difference and the only way to understand is to use them for yourself.
