Besides reloading, anybody had success making one more accurate?

Anybody tried a screw to create a pressure point? Or had success pulling the barrel extension and rebarreling?

Or anything else?

start here?

No. There are made for hitting a deer at 150 yards. Big waste of time and money trying to make it something else.
My advice: get a bolt action.

Remove the barrel and thoroughly clean and remove copper. Polish chamber if necessary. Reinstall and torque nut to 20 ft lbs w/red Loctite. Torque forend screw to 30 inch pounds. Make sure bracket is snug next to receiver. When shooting, support forend at rear near receiver. Not towards gas block. Use 150 grain bullets.

dpcd is correct, they were designed for quick shots at close quarters. 1 1/2 inch groups are the norm. Keep the rails and bolt lubed. They don't run well dry.

Thanks all

AS REmington warranty (years ago)...It's a matter of redcord that 4 inch group of three shots was considered acceptable by Remington Arms

Take dpcd's advice

Wow, Duane you are being nice.

In those times, the 70's thru the 80's, we were told by the same Remington Service Mangers that you dealt with, that the ammo specs was not to exceed 3 MOA @ 100 yds
So there was no need for the 742 rifles to shoot less than the ammo spec

The ONLY 742 I we knew of that shot very well, was in 243, and the guy only had one arm.
So due to the heavy barrel and the way he had to rest the rifle he could keep it under 2 inch groups at 100 yds.
I also would think that the handloads I made for him may have helped in that department as well

The model 760's pump rifles would shoot better due to the lack of gas system rattle and slam

Hey Bobster,

FYI, this worked great. The rifle's accuracy had fallen off from around 2.5" groups to 5" groups with almost any load. So I think the barrel nut had loosened or the copper buildup had gotten so bad it was really affecting accuracy. Anyway, this did the trick. It was shooting one load into 1.5" even after the barrel was hot. Another would keep 2.5".
Good enough for hog hunting at night.

I knew it would!

Trade it for a REM 740 pump, for whatever reason they all seem to be accurate as all get out..Popular with the CIA who tested them out and Ive had 4 of them, all shot under 1,5"..but they rattle like a bowling ball in a box car however, and that's aggravating..

True story: While in Wisconsin. a customer had us mount a 6-18 scope on is 742 to "Make it shoot better"

Our shop no longer accepts 742's because you can't get parts anymore. Especially boltheads which are prone to cracking at the bolt nose. The root of most problems with them is poor maintenance. They must be kept clean and lubricated. The bore and chamber need to be cleaned after every shooting session. When they are dirty and run dry there are tremendous forces put on the internals to overcome friction and mechanical lock. This farks up the bolt and guideways in the receiver leading to permanent failure. Rough, dirty chambers cause cases to stick and eventually the bolt nose extractor mortise will develop a crack from stress caused by the extractor. Accuracy is related to bore condition, barrel nut torque, forend screw torque and technique. Off the bench shoot with bag near receiver free recoil. Any upward pressure on the forend sprays shots.
