Agree - the old Rolling Block triggers are the worst.
My .45-70 Pedersoli/Navy Arms Buffalo Rifle has a three-pound pull. Granted it's not an original Remington, but either Pedersoli, Navy Arms, or a previous owner got it right.
With the exception of the 1891 Argentine, I installed Timney's in all my Mausers, and the lone 03A3. The two Swiss
K-31 triggers were ideal, and may have rivaled pre-adjustable commercial triggers.
I've never fingered a Savage Accu-Trigger, but the Ruger American's is nice. I changed the factory return spring with one from a ballpoint pen, and dropped the pull to two-pounds.
I only shoot charging sabre-tooth targets, so two to three pounds works for me.
