Like most of you as of late, I have been having lots of problems with my SVT-40. Most ppl just end up putting them up for sale after about 40 or 50 rnds because they are having so many problems trying to get the rifle to shoot properly. It can be very frustrating trying to fix all the problems that can arise. This is why so many ppl sell them after so little rounds. Now that I have most of my problems fixed or being fixed, I'd like to share my experiences with you so that those of you out there with SVT's or are planning on buying one, know what problems can arise and how to solve them. In the end I think these are great rifles, once they are functioning properly.

Loading. There are many problems that can be found in the loading, and ejecting processes that has much to do with the magazine and stripper clip not being properly loaded or pinned correctly. First thing to look for when picking up the rifle's magazine is to make sure that it can hold the full 5 rounds. Take the magazine in hand and hand load the 5 rnds. If it cannot (mine for instance held 4 1/2 rnds and the fifth kept jumping out) you have to have the mag repinned. You can do this yourself or have someone else do it. Its not hard, just make sure its still legal in the end.
The other problem can be with the stripper clip itself. Not having your rounds loaded in the stripper clip properly can lead to a lot of things like the rounds not sitting in the mag properly or ejection problems like stove pipes or rounds still on the face of your bolt, slightly canted to the right (my latest problems solved today). When you hold the clip with the rounds facing straight up, one round should be slightly higher than the next. To do this, put the primer of your second round on top of the primer of the first round, and so on. You end up with all your tips in line at an angle. When you load the clip, load the highest rnd last and push at the base of the round. Your finger/thumb should run along the clip as you load. If you struggle with this, your doing it incorrectly (as I found out the hard way).

Ejecting. Some ejection problems can be solved by stated above. Another thing to try is to adjust your gas setting. Each number on the regulator is for a different hole. To adjust it, remove the gas piston and adjust by hand with a five sided wrench or in my case (I find this easiest), tap the regulator out so you can move it by hand. Use something to hold the regulator in place as you adjust it. I use a stub tipped pencil. Ensure the number your selecting is facing straight up on the rifle. Mine has a little hole that I line the regulator up with. If your like me, I have mine at the highest setting. As you may or may not know, this is not good. Try and keep it on the lowest possible setting. As I had it set on the highest setting before I had help fixing my problems above, I'm now going to lower my gas setting. You'll also find this to be better on the rifle itself.

Sighting. If your rifles like mine, its not putting the rounds right where I want them. All your adjustments are done on the front sight. You move the sight opposite of the way you want the rounds to go. For instance, want to move the rnds to the left, drift the front sight right. If you want to make your rounds go lower, raise your sight. Getting at your front sight is tricky. I can't find any tool that is capable of doing the job, so I'm making my own. Take a bolt that you can fit in the hood, cut and file a space for the sight itself. You may have to drill a hole for the sight to sit in as well.

I hope these tips have helped you out. There are lots of ppl who have helped me get these problems solved as I am in no way an expert. Thanks to Stevo, SVT-40, and Navy Shooter for all your help.
 
Good to know the magazine is a weak link - on yours. Haven't had any sort of trouble with either of my SVTs. In fact I almost think of them as being big SKSs.

The 4 1/2 round magazine capacity problem makes me wonder if SVTs need to have the first round strip off one particular side for the rest of the feeding to be effortless. Garand clips from the arsenal always have the first round on one side. Filling them by hand takes a chance with the first round cycling improperly. (Garands were known to be tempermental, but the bad attitude was ruthlessly engineered out of them by Uncle Sam.)

As for stripper clips. I don't have any, so I've always hand loaded from the top. Keeping the rims (they're not called primers BTW) staggered forwards is second nature to a Lee Enfield shooter.

The gas regulator adjustment is a skill known to shooters who learned on FN C1/L1/FAL rifles. Just about every other military semi auto designer assumed the soldier was too thick to appreciate the relationship between lots of gas, sharp whack on the parts and less gas, more gentle cycling. Reducing gas flow to the smallest hole will fail to cycle sometimes, but won't beat up the rifle and your shoulder.

Front sight tools should be kept in the butt trap of every rifle that needs one. Under the buttplate on the SVT since there is no trap, but a big hollow.
 
I've heard a lot of complaints about SVT's, but mine has never so much as hiccup'ed. Maybe I just got lucky.

As the original poster said, don't give up. THe SVT can be a joy to shoot.
 
I have 2 SVTs, and a half dozen mags of a varying conditions. No feed, or ejection problems here. the first shot will occasionally be a little off from the rest, but I only notice this wehn I am benched, and even then, it only happens sometimes.

I have seen greatly varied stripped quality on 7.62x54 surplus, however. I don't really use the strippers though. Most of the ammo that I see on strippers have flecks of a tar-like substance on them , and have to be cleaned individually anyway.
 
I haven't had any problems with my SVT. Other than the fact when I received it, the gas system was completely rusted in place - but I was able to fix it without any special tools or skills.
 
Gaah, I never even thought about locked rims causing problems for you. I took it for granted you'd know that.

Glad to hear it's getting better.

I've noticed this as well. My SVT groups very well, even off hand, but the first shot out of the case is usually 2-4 inches off of where it should group. I was thinking that it could be due to the handguard shifting with handling, which is then righted once a round is fired.

Who knows though.

Could be. The reality is that I only have about 400 rounds through SVTs so far. It may even be that from time to time I am not used to the trigger, or just about anything.
 
so there could be parts in there I never knew about?

I never thought that there could be parts in the butt. Thought that was just recent (C7/M16). I've never heard of that for milsurp weapons. Would it be possible that there could be something in there I/previous buyer didn't know about? How do you take off the butt plate to check? Just those two screws I imagine?

Oh hell yes, I have spoken to people that have not only found the cleaning kits, but windage tools, and even small notes, pictures, or with scraps of paper with odd saucy comments from the armourers. Milsurps are fun stuff. :D
 
Did I miss something here? Neither of the two SVT's I owned had even the slightest of problems aside from my getting them with the wrong gas setting being used by the previous owners (maybe why they sold them?).

The last batch of imports almost all had the mags pinned to 4.5 rounds. Whoever did the work was a BONEHEAD.
 
It's not a good idea to put the gas regulator to highest... :(
The bolt begins striking the frame too hard and the frame bends more and more, the ejection problems come back at some point and there is no more room to fix them. I personally would never go for higher than 1.5.
 
since im getting an svt 40 this thread is very helpful. will see how mine is an let all know. i got /found a b-square scope mount for mine, plan to play /hunt a little perhaps.............
 
I took the buttplate off of my SVT to search for treasures, but there was nothing, not even a hole for storage, I guess it;s because it's a late war AVT stock.

NB.nagantsniper, after playing with my SVT I've been thinking that it's make a great hunting rifle. Despite being a little long, is incredibly well balanced for offhand shooting, maybe not the best brush gunb but I think it'd be practical enough to go at whitetails from a treestand or out in the open. I'm debating whether to bring it or my jungle carbine out as my moose backup this year.
