Has anyone that is only concerned with keeping a bullet from slipping in the sabot ever tried scuffing bullets with sandpaper or emrey cloth?I have scuffed a few barnes bullets where the bullet will touch the sabot holding them so the scratches run the length of the bullet and they did not lose any measurable weight. I do not want them any bigger, I just want the bullet to bite into the sabot so they get all the spin they are supposed to. May be a crazy idea but I thought I would try it. I do not own any files that are not rusted pieces of C#$%. Any opinions other that Rusty is off his rocker?

Rusty........a light knurl will do the same thing. If you take a large square of sand paper and a flat stick, you could roll them, much like knurling with a file and get the same effect. I used to do it with the .50, but never came to any conclusion as to whether it helped accuracy or not? Now, I knurl only to obtain proper fit for sabot less shooting.

i use a ch4d cannelure tool,have experimented with as many as 4 bands of cannelure on a bullet,only one needed & yes inside each spent sabot is a footprint of the cannelure assuring no slippage,hot or cold,just good insurance imo

Here is my theory on bullets slipping in a sabot. If there is a hole in the base of the sabot....the bullet slipped ;D My analogy for a bullet slipping is the same as if you were on a skateboard and grabbed the bumper of a stopped car. As the car accelerated either you were able to hold on or you were not! Once you lost your grip, you could never regain it since the car was now too far from you to grab it! If you lost your grip...you became the hole in the sabot...if you held on then you are part of the nice group 100 yards away  edge. |

I have been thinking about this some. I would NOT want to use emery cloth to scuff bullets for fear it would leave grit on the bullet jacket that might migrate to the bore. I would especially hate to scratch up my Pac-Nor 45. It may never happen, as long as you use sabots, but I am the negative and pessimistic type. Some see a glass half full, some half empty, but I see it bone dry with a crack down the side!

Ya know i think I'm gonna lightly knurl some 200 sst's for my 36 grains 4759 load in my 45 pacnor and see if that load will hold up better,,, only blew 1 sabot out of 15-20 with that load and it shoots really well, that was in warmer weather as well,,, a very, very light knurl with a cross pattern light rasp should really grip a sabot

and the one that blew blew out the center of the sabot,,, found that part, nice little round piece of light blue with the number on the bottom,,, a slight knurl should really help

I had a couple of 50 cal MMP-SB sabots blow like that last Saturday. Only found a disk cut cleanly out of the sabot base. No petals, and no cup.

Yes that was a neat find, never had that before, I have blown sabots in my 50 cal and found one long string of plastic goo,,, but never that little round disk,,, my kids are my sabot hunters,,, I shoot off of the deck and they search the yard for me,,, ahhh the wonders of a herseys kiss reward,,,,,,
