longtom, I used the search button in the upper right corner and entered the words:

sticky and bolt

This thread popped up in search results. It's worth reading all the way through:

Difficult bolt movement and extraction in usually a sign of excessive pressure in your ammo. Switching to another brand might well help.

Thanks for the info and for pointing me in the right direction

It's the ammo. I haven't seen signs of excessive pressure in any ammo I've fired, but the laquer cased stuff is usually the stickiest. Wolf FMJ is the best as far as smooth bolt operation.

[Sir Galahad]

In both my Finn M-39 and my 91/30, the Wolf 200 grain softpoint is difficult to cycle the bolt with. The best ammo I've used so far is Hungarian milsurp. It has laquered cases but the laquer is even and not goopy.

The best ammo I've used so far is Hungarian milsurp. I agree that some of the Hungarian is very excellent ammo. However, be aware that there are a few types of Hungarian surplus on the market and not all of them are good.

147 gr. LPZS in the green "spam can" is great ammo. It's made in the late 80s. There is also a silvertip variation of this made in the early 80s. The so called "Etalon match ammo" is made from this stuff but is supposedly carefully weighed and with more strict QC. It's varnished steel case with red sealer at the crimp and primer. The bullets are steel core. I shoot this stuff most often because it's cheap, fairly new, accurate and reliable.

174gr. Yellow tip "heavy ball" is good ammo in my experience shooting it in three M/39s and 4 different Mosin carbines. It's 50's production and comes in a rectangular silver colored can. The rounds have copper washed cases, the bullets are steel core. The rounds are packed 20 to a wax paper bundle inside the can.

172gr. Silver over Yellow tip. Bad mojo. Avoid this stuff. It's 70s production. The rounds have copper washed cases, the bullets are lead core. A lot of guys have reported trouble. It's very hot and I had major extraction problems in the two rifles I tried, one M/39 and one carbine. The story is that it's machine gun ammo and too hot for Mosins. I don't know if that's true, but it doesn't work well regardless.

Yugo 180 gr. is also very excellent ammo if you can find it. It's late 80s production and comes packed in cardboard boxes of 15 rounds. The rounds have brass cases, the bullets are lead core.

All the above is corrosive.

i just picked up some silvertip 'slovakian stuff that does this all the time... it's not so much a problem extracting the case, it's lifting the bolt to cock and unlock it....

i thought there was a problem with the bolt, but i also picked up some barnual SP as well and it cycled real smooth through the old 91/30....

both were as acurate as the rifle, compared to that brass cased surplus i used to buy...

I have the same problem with both my M44's. It usually takes a healthy slap upward to open the bolt. My 11 year old doesn't seem to have to fight it too hard though (the little recoil junkie put close to 80 rounds through it the other day :eek: :D ), maybe I'll go ask him if there is a secret ;) .

My experience is exactly like y'south's. Czech ammo took a mallet to lift the bolt. Barnaul SP's, jes' fine.

[OEF_VET]

I've had the same problem although I wish I would have kept track of the ammo I was using at the time.

[Freightman]

I think that it is rifle sensitive as I have the Czech silvertip which is great in both my M91 and M44 Russian, I had a Hungarian M44 that refused to open on the same ammo.

[AZTOY]

Same thing with my M44:banghead:

The only ammo, i have tryed so far has been Wolf and Hotshot.

[DMK]

it's not so much a problem extracting the case, it's lifting the bolt to cock and unlock it.... That is the symptom of hard extraction in the Mosin-Nagants. I suspect that in the Mosin bolt design, the cartridge starts to move back while you lift the bolt. I haven't looked closely at it yet though.

In my experience, hard extraction has always been ammo related. BTW: Czech Silvertip does have a reputation for difficult extraction in a lot of Mosins. It is good, accurate ammo though if it works for you. I've been lucky that it works fine in all of my Mosins.

[Okiecruffler]

I have a 91/40 that did the same thing, until I backed out the bolt that holds the mag body to the reciever a little bit. Then it worked just fine. Except that it doesn't shot in the same zip code, but that's another story.

[Sylvilagus Aquaticus]

When I've been out shooting my M44 with 200gr Wolf SP I've occasionally wondered if I should pack a cheater pipe in my kit. The 148gr. FMJ Wolf hasn't given me that particular problem, though.

I suppose it could be the lacquer coating as I've noticed a lot more goo coming off when I use a chamber brush when it's all done for the day.
