I have 2 R700 builds with another in the works. One is a trued and blueprinted 700 SA in 6.5x47 the other is a factory 700 SA with no machine work in 308. Ive noticed that i can get the trigger on the 6.5x47 a few ounces lighter than the 308. Both have timney calvin elites. If i try to turn the 308 trigger much lighter it will drop the firing pin when closing the bolt. Now the rifle im building a 223 that id like to have a pretty light trigger, around 6-8oz. Probably end up with a jewell or a bix n andy. Is there a trick to getting them to function with a light trigger? Is it in the trigger design or is there modifications that have to be done to the action like in the action timing?
