You remove the cleaning rod?

Ever since I've owned my SVT-40, I've always had inconsistent accuracy. 5 shot groups ranging from 6 - 8" at 100 meters with the groups being inconsistent forms such as a string groups, triangle groups, and box groups. The other day I was looking at WWII pictures of SVT-40s in action being used by German troops. The Germans did figure out how to make the SVT more accurate and taught troops in field accurizing which led to the SVT-40 being used to devastating effect against its own people. I noticed in almost every picture with a German troop, the cleaning rod was removed. I thought, could this be an ancient Chinese secret that only the Germans knew or is it that everyone lost their cleaning rod? I only noticed the cleaning rods were gone when a member here claimed his SVT-40 was more accurate with the cleaning rod removed. So I went shooting today with my SVT-40, cleaning rod removed, to put it to the test. I must admit, I've very surprised with the results.







5 shots on a paper plate. This is the first time ever that I was able to get all 5 shots on paper! Nothing else has been changed just the cleaning rod removed. I was using 147gr, non-corrosive, Berdan primed SCDS ammunition. These 5 shots are with in 4". All 5 shot groups made with this rifle before was always 6" or worse. I also did a 5 shot group at 50 meters. A shocking 1 3/8" group! Never done this before! I then tried a 10 shot group at 100 meters.





I was simply amazed! 10 shots with in the usual 5 shot group but the bulk of the group, 7 shots, is with in 4". Most of the group is consistent and with in 7". In the picture, the 10th shot is down in the right corner. The SVT is covering up a 3 shot group that was made with my .223 Vz 58. Before this, my SVT would not get all 10 shots on paper and what was on paper was scattered all over the place.





So is this an ancient chinese secret or am I on crack and all the suddenly became a better shooter with my SVT? Or perhaps my SVT just happened to be shooting better than it usually does. If this does change the accuracy of the SVT, what would removing the cleaning rod be doing to the rifle to make it more accurate? How about some other CGN'ers put it to the test and see if removing the cleaning rod changes the accuracy of your SVT-40. 4moa, to me, is good enough. Its as accurate as your typical SKS with a lot more punch. I would actually feel comfortable taking the SVT out deer hunting at short ranges if this kind of accuracy remains consistent. Before, I wouldn't even consider it.

How well does the SVT-40's groups stack up against two other rifles?

I wanted to know as well so I brought along 2 other rifles. My Norinco M305 and my .223 Vz 58. I don't have a lot of trigger time in with my M305 and it was a good, rediscover why you like the M305, shooting session. Although my M305 didn't get as good of a group at 50 meters as both the SVT and Vz 58, the M305 really began to shine with the 10 shot group at 100 meters.







I was using Norinco 7.62x51 ammunition. 8 of the 10 shots are with in 4 5/8". 1 shot didn't make it on paper but the entire group is 8 1/2 inches. Compare the M305 group to the SVT-40 and they're pretty close considering the SVT put 7 shots in 4". Definitely battle rifle worthy. I typically get 3" 5 shot groups with my M305. I've once had an amazing 1 7/8" 5 shot group that I have hanging on my wall but that is definitely a fluke.





The .223 Vz 58 takes the prize but not by a whole lot. Just a note, this is this .223 Vz 58's 800th round count. There have been some minor issues and they have been with the C-Product 10 round LAR-15 mags only feeding reliably 95% of the time. The C-Product mags also fail to function the last round bolt hold open turning it into like an AK having to hear the click and then change the mag. The USGI magazines work a lot better. Anyways, back to accuracy. The .223 Vz 58 can be hit or miss with accuracy. The worst groups I get with it are 3" 5 shots and best being damn near close to 2" with a consistent 5th round flyer for some reason. The 5th round flyer seems to go away when I'm using 62gr or heavier ammunition. I was using American Eagle 55gr. The 50 meter group was 1.5".







All 10 shots made it onto paper with the bulk of the group, 8 shots, being with in 3" well the rest of the group was with in 6". The 6 shots close to center is 2 inches!
People love to hate my .223 Vz 58 for some reason but its one of my favorite plinking rifles.





Bottom line, I grew a much better respect for my SVT-40. I always regarded it as a cool looking but inaccurate rifle. The rifle looked so cool that I didn't want to sell it even with its ####ty accuracy at the time. Maybe removing the cleaning rod didn't do ####, maybe it did. Won't know until others give it a try and see. I also rediscovered why I like my M305. I will admit, my first 2 groups at 100 meters with my M305 was complete #### since I haven't used it in awhile. If you fail to put in the trigger time, your proficiency with the rifle will diminish. Hope you enjoyed the range report. I wonder how many people actually read the whole thing. ;)
 
damn, I have a 1941 Tula, and using the 185gr non-corrosive MFS ammo from trade ex , I was getting 4" ten shot groups easily. At 330 yards , I hit a 12" gong, 45 times out of 55 shots. I love the accuracy of mine, and it has the cleaning rod still in place. Cant wait to try it with the rod out!!!!!
 
Removing the cleaning rod lets the barrel wobble more freely. It can also help to make sure the barrel is not coming into contact with the forend wood. With that, plus good ammo and a decent scope, you will get ragged hole groups when shooting from a sandbag.

Thanks for the explanation. I figured something was up with just all the suddenly the gun starts behaving more with the cleaning rod removed. First time ever I managed to hit the 275 meter steel goat a few times with it too.

You are welcome. It's all to do with oscillation and and harmonics. Oscillation is always there, it's that which makes the barrel wobble. It's caused by the twist imparted on the bullet by the rifling. To be accurate the barrel must be in harmony with the oscillation and it can not be if it's movement is restricted. Check that the barrel is not contacting the stock, it's quick and easy to do.:)
 
Mumbles: Great thread! I believe it was my recent comment about removing the rod that you referred to. I did it after seeing the ultra slow-mo movie on you-tube where you can see the cleaning rod bending and actually riding up one side of the barrel- didn't look like a good thing. After seeing your results I can't wait to try it with my other SVT's. Lyman- as far as barrel-stock contact, I've been checking how it is set up on my collection of refurbs and the vast majority do seem to have significant up-pressure at the forend tip with the rest of the barrel free right back to the receiver ring. I've found a couple that don't have contact at the tip but haven't had a chance to try them out yet. I've also found there to be two different types of lower metal guard ( the one that slips on the front of the forend). One has a ring that looks like it was meant to have the barrel rest on it (and it does), the other lacks the ring and the barrel rests right on wood. Anyone out there done any experiments to see how free floating affects accuracy with the SVT 40?

Free floating affects the accuracy a lot. It's never going to be completely free because of the metal hand guards, but it helps a great deal. Before I sorted mine out it was all over the place, now it's a tack driver. even though the bore looks like $hit.:)
 
Lyman: Thank's for the info. Going to experiment with one particularly inaccurate one as soon as I can get to the range again. Not highly motivated with the mercury at -20C.

I've very interested in seeing results from others. I'll check to see if my barrel is coming into contact with the stock right now. What really impressed me was the 1 3/8" group at 50 meters. If I would of shot more that day, only had 20 rounds, I probably could of got a 3" 5 shot group at 100 meters.
 
Just checked with a $20 and the barrel comes into contact with the stock at the tip on both sides. One side of the stock has a repair and that's whats contacting the barrel and the other side contacts the barrel from the tip to about an inch down. I'll post a picture to illustrate what I'm talking about. You can see the stock repair in the picture. Both sides contact at that point.

OK What you need to do is get hold of a length of wood dowl as near to the diameter of the channel as possible. Wrap sand paper around the dowl and gradually remove the obstruction. What you may find is that once the obstruction is removed the barrel will be contacting somewhere else, repeat the procedure as necessary, keep checking !. You have been shooting your rifle with a built in miss :)
Take you time and all will be well.

PS I would guess the vast majority of refurbished SVT 40's need sorting out.
