I have a Yugo model , that when using soft point or varmit rounds deforms the tips of the bullet on loading , sometimes to the point of actaully jamming the round . Is there a fix for this or is this life? should I just stick with shooting FMJ? any info helps .
Thanks |

The rifle should feed anything you put through it,both my Yugo and Chinese feed anything I throw in it commie,commercial or hand loads with no problems. Sounds like you have a mag issue and one of the feed lips may need a slight adjustment,does it do it when feeding a rd. out of one side or both.
You can put one less rd. in the mag to make it feed from the opposite side to test that if you have been experiencing that with a fully loaded magazine. You can take the mag out and look at the feed lips from the front and see if one looks lower or higher than the other if you make any adjustment to them less is more. |
| I have used it with my stock 10 rd. mag. and it does it , I then bought a Tapco 20rd and it does the same thing , only on the right side of the mag. and as it starts the load the lead tip of the bullet hits the face of the breech and jams it up. Now if I use FMJ no problems at all. But I plan on shooting carmits rounds , and was hoping that there was a fix , but if not then I live with it . now the sad thing is , I bought this rifle and it came with 480 rounds of wolf soft point bullets .

I have three SKS's that I use for hunting, and I experience the same Soft Point gouging that you are explaining. All three guns feed FMJ without a hitch, and feed the soft point as well. I chose these three guns out of the 30 others in my collection because they group under 2MOA with open sights, even with the SP. But the aerodynamics have to be affected by this gouging. When I get around to it, I will do what is called the 8 - 4 feed ramp modification on these three guns to eliminate the point gouging issue. The "feedramp" on an SKS is a very loosly defined term, as it truthfully has no feedramp. But if you look right below the chamber, you will see a 90deg angled ledge that is part of the receiver. This ledge can be VERY LIGHTLY beveled to a 45deg angle from the 8 o'clock to 4 o'clock position, and I have had feedback that this beveling will greatly reduce the soft point gouging. Care should be taken to remove only the amount of material necessary to eliminate the nosing or gouging problem. Hand cycling in a safe environment should confirm your progress. Some SKS owners have even slightly cuffed the sharp edge at the bottom of the chamber, but I have also read accounts where too much material has been removed from this area and caused bulging or splitting casings. I am going to avoid altering the chamber mouth completely, and live with the "feedramp" beveling. I don't know if I'll ever reduce the 2MOA grouping that I'm getting with these guns and the Wolf 154g SP ammo, but it just bugs me to eject an unfired round after a hunt and see the gouge in the point..... .... maybe I'm too picky.

| Well, if your too picky then so am I , I like to know that I am loading a accurate round , and I also believe that if the tip is damaged especially to this degree that it does affect the MOA. I think I wil lstick to FMJ because all I am really doing with this is coyote hunting, and FMJ will get the job done . I am not a big fan of modifing anything in the chamber and I am not a gambler so...... FMJ it is . Thanks too all ! |

This process is to grind out the chamber in a ramp to feed the ammo. I have also read some posters state that this screwed up their weapon even more. So this is my idea (I have not tried it nor know anyone that has: Get a buddy that has either a Mig or Tig welder and put a bead (build it up) between the receiver and barrel, only .315 wide center, then take a dremel tool and grind down the weld forming a feed ramp, see pics. Without ramp feed ramp without With ramp feed ramp with After you build it up you will have to adjust it so that the bolt closes properly.... |
