This rifle shoots great....in the warmer weather. But when I get it out for opening day in Northern Wisconsin it always, and I mean always jams after the first shot.
I had a gunsmith tear it down, and he worked on the metal parts, while I refinished the stock. That didn't help either.
I clean it after any extended time on the range, and after deer season. I thought that somehow to much oil was present and was causing problems in the cold weather, but I still have the problem even after the gunsmith cleaned it.
Specs:
Winchester Model 100 in .308 cal. - Semi-auto
Rem. 165 grain PSP Core-lok
Have you tried any other ammo?
What kind of jam? Stovepipe? Won't eject? Won't rechamber the new round? What is it doing / not doing?
I'm guessing you have done this already since you had a smith clean it, but I'd clean it whistle clean and leave it bone dry of lubricant adding only a little of the non grease based lubes ... like teflon, etc.
And trying some other ammo might help, but it sounds like you may need a smith that intimately understands the Win 100 and have it checked out for parts wear.
The model100was recalled for problems with the boltand action, you need to make sure that you'res was return and repaired before you keep using it I have seen soon that have blown out the breech so be carefull with it. they are great guns I have one in .284 and love it.
It's not a Stovepipe jam, but the spent casing is not ejecting, so the next round is not being chambered. I can usually clear the jam with my fingers, without to much effort.
I haven't tried any other ammo. Any thoughts??? I really haven't used anything but Rem. ammo.
I know .22s are not the same as .308 autos but my marlin used to jam on me all the time when i used federal ammunition, after finally using up all those rounds i bought remington ammo and after never having it jam figured out that it was the ammo, so just by switching ammo i now have no problem with my .22, hope you figure out your problem, good luck,
I had a similar problem with mine. My rifle is a pre-64 with cut checkering and not the basketweave on the stock. I did send my gun in during the recall and they replaced the firing pin. When doing so they marredsomething slightly inside the bolt after my local gunsmith polished this it solved the problem. This is only after changing the extractor and ejector to no avail. Also you may want to check your magazine as mine was slightly bent and would only function properly when loaded with 2 rounds.I purchased a new clip and this corrected that problem. Therifle is finicky and does have to be kept very clean in the chamber or jams occur.
This doesn't tell us much! What, specifically, did he do to the metal parts? Are you sure what he did actuallyimproved its functiooning? Have you got any idea of WHAT CAUSES the jams during cold weather?
You could TRY removing ALL oil and grease/dirt from all moving parts, then relube with a totally dry MOS2 lubricant or powdered graphite. That's what I used to do to winterize rifles (including M1's and M14's) for use in interior Alaska at temperatures of -45 or colder.
