The 740 is a slide action rifle, so I assume that you operate the action smartly to promote proper function. What is the nature of the jam?
1) Spent cartridge not removed from the chamber - extractor system failure
2) Spent cartridge not tossed out of the rifle - ejector failure
3) Cartridge won't feed into empty chamber - magazine alignment failure.I must add that the Remington model 740 is actually a semi-auto gas feed magazine rifle.I would seriously consider that the rifles gas system(piston,and gas tube could be built up with carbon!)This would require that the rifle be taken apart and the gas system be cleaned,so the rifle may function properly.

After the bolt carrier is removed, the pin is driven straight down to remove.
Yes, I also have a Remington 244. I haven't it shot it in years but it used to work great with Winchester 6mm cartridges. Seemed to jam more with Remington for some odd reason.
The Remington Woodsmaster 742 is a semi-automatic rifle introduced in 1960 as a successor to the earlier Model 740. Designed for hunting, it features a gas-operated action and was offered in various calibers, including .30-06 and .308 Winchester. The Woodsmaster 742 was produced until 1980, during which time it gained popularity for its reliability and ease of use. Despite being discontinued, it remains a well-regarded firearm among hunters and collectors.
You can't shoot reloads in the 742 or it will jam. My guess is they expand just enough to jam. When I first got mine 18 years ago I had the same problem. Since then I only shoot with new shells.
