Copy that Mel. Yep....most of the 742's, I get in have just been neglected, from season to season. Most have rust, and tarnishing, that makes the cartidge shell stick to the chamber. I have not had any that have been pitted as bad as what you describe. Not sure how I would deal with one of those, if it came into the shop. Short of a barrel replacement...he.e..e.e. Problem with the 742's is to do a proper cleaning job, you have to remove the barrel, and brush out, and polish the chamber when they get to hanging up, (jamming). Most folks are not interested in getting that far into one. After I do my little proprietary process, I always recommend they invest in a Hoppes, Bore Snake, caliber specific, and follow mfg. directions. One extra tip I tell them, is after a few pull throughs with the bore snake, dip the last inch or so of the snake in Kroil, and let it soak in, then do a few pull throughs. It will leave a film of protective oil preservative in the chamber bore, and be ready for next season. There is a ba-jillion 742's out there, and your gonna run up on this problem sooner or later in you shop. This is what works for me. Have had not complaints as of yet! he.e..e.e.e..talk soon. Jeb.
obviously, I'm in the presence of greatness.........let me take advantage of the knowledge dished out for free.
just kidding fellas. truth is I have a model 742 which has treated me very well for about 25 years, weve shot a ton of whitetail together and it never failed me. Just keep her clean and fire away. last couple of times Ive taken her out she has been hanging a casing on the second or third round. not sure what to do. she has spent the last season on the rack due to lack of confidence. any help would be appreciated.
Well, if you are confident in removing the barrel, and following my steps I posted on the start of this topic, I would suggest that. I'll just about guarantee you thats the problem. If not...I would suggest a Hoppes, "Bore Snake", in your caliber. Cock the action, and let the magazine keep it open, and pull that Bore Snake from the chamber end, about a dozen times. On the last pull, dip the large end of the Bore Snake, in a good gun oil, (Rem Oil), etc. That should solve your problem, if it has served you this long, so well. If not.....a barrel removal is in order.....which aint that big a deal, just a thumbuster in getting back together. Hope that helps.
I would think that one of the problems these firearms suffer from, the ones chambered in Military rounds, like the .308 Win/7.62 Nato or in 30-06 is the plentiful supply of cheap mil-surp ammo. One thing you should never do is to treat the claims of being Non-corrosive as being an absolute truth. Even the USA made stuff can have mercury based primers and while the government accepts them as non-corrosive that is not the case This is more of a problem if the stuff you practice with is from overseas. I know this from personal experience. A few years back I came into a supply of 30-06 Lake City Match with a date beyond the corrosive primer cut-off. It shot well in my pet Model 70 Winchester. For hunting the FMJ bullet was not OK, so I pulled the bullets and replaced them with a commercial equivelent, went to the range and verified my zero. Time was short, so a complete breakdown and cleaning was not possible. I filled all my tags that year using that ammo...total of(maybe) 12 shots..Thanksgiving was upon me and again cleaning was put off...when I finally got to it in January, the bore was completely pitted..the barrel was ruined..the 30-06 barrel was re-bored to .35 Whelan and is now my Moose and bear gun..point is clean your guns more so if you firee any mil-surp or commercial ammo made overseas.....
thanks for the quick reply fellas....i'll give her another go ......
I have a 742 .308. The feeding prob I'm experiencing is the tips of the bullets are getting shaved off on the bottom. I've tried changing oal from 2.73-2.85. Always the same prob. Any ideas would be welcome. The rifle is clean.
Is it possible they are getting shaved off by the magazine box? Where do you see metal in the feed area. Or do you. hmmmmm. good one.
Sounds like the magazine is feeding the ammo up and under the edge of the feed ramp. On this modelthere are several sizes of magazine latch numbered 0-1-2-3-4 in the OLD and NEW styles each is individually fitted to the gun..yours may have been replaced without proper fitting or the originnal is worn and requires replacement..Any of the Authorized Rem repair station can help to find your nearest one check with www.remington.com
Not the mags. It seems to be shaving off just on the edge of the chamber. I wondered if bending the clip would change the angle enuf to fix it. Or taking a gentle grind to the feed ramp? I'm only gonna shoot enuf to find a decent load and then hunt only. Those new deep curl bulletsw would probably solve my prob. But, JEB, how much can I change that ramp angle?
Zeke. One is orig clip. It fits loose. Another is after market. It fits solid. How can I tell if it's worn? Thanks a bunch guys.
