I am curious if anyone has tried using something like a pop rivit washer under the bullet, but inside the sabot? It would have to be just the right size, but it may support the plastic a little on those bullets with a radiused base. Boarhog I have shot aluminum washers under the boattail TMZ/SP in the .50, accuracy was better than the supplied yellow sabots and it did away with the sabot failure I was experiencing with the 245/250's. Dave D and the more experienced guys probably have experience with this from their days trying to get the .40 cal bullets to shoot in the .50 cal.

Sounds like there is some potential success with the right size washer. I had lots of blown sabots when I tried testing several boat tail bullets and BT sabots. I think I'll see if I have any washers that might fit. Bh

:)i could be wrong but im pretty sure the washer would have to be slightly larger the .400 which would require machining a groove in the bottom of the sabot to snap it in.this is what we did in the .50 with .40's. btw by doing this the sabot was almost indestructable.

Find a washer and match it up with a endmill of similar size and you could use that to cut the inside of the sabot You could also buy aluminum washers to cut the weight. How about a .40 cal. veggie wad in place of the washer? (still using the endmill to cut the base) Richard

They seem to do a really good job in my application which is primarily just to make a better seal in the groves. I can't imagine they are tough enough to help a stressed out sabot very much. They are certainly cheap enough to give them a try though.

Chuck...........I don't think the wad or washer is adding any strength to the sabot............it is just eliminating that beveled edge on the bullet that makes it want to push thru the sabot? If you can eliminate the bevel, it might protect the integrity of the sabot? And actually, I don't even think you would need to cut the inside of the sabot? I don't cut it to use the XTP? It would just make it an SST with a flat base! Richard

Since veggies are usually groove diameter or bigger, would they even fit inside a sabot without altering?

Today, I did some further testing of IMR VS H-4198. I'll do a range report with pix soon. Relative to this thread though, I re-visited one of Richard's duplexes that shot pretty well for me in the past. The load was 5/65 N-110/N-120 under a 200 gr XTP, in a Harvester smooth blue sabot. Speed was right at 3000 fps, and the group was about 1.5" for 5 shots. Since it shot pretty well, I thought I would try the same load with a 200 gr SST. No good!! The 2nd shot blew a sabot, and almost cut an Oehler diffuser riser in two. Hmmmm, I took a look at the SST, and the base had a very pronounced radius, so I thought it might be a good time to try the aluminum pop rivit washer inside the sabot. At least I cut paper, but the sabot still failed. I found it and it had been drilled, instead of shredded. There was a definite mold of the washer in the sabot base. Perhaps it was just a little small to accomplish protecting the sabot. Boarhog

I just give my SST's and BX's a 10 sec knurl and that seems to take care of the issue. I think we just need to get Hornady to make a flat based SST.

I wonder what the base on the TEZ .45s look like. They continually blow the RCR in my .50 with the same load that almost one holes xtps. This could explain it. Just checked, the .45 xtp is perfectly flat, while the TEZ is more beveled, but not as much as the .40 appears to be. I may have to flatten some on the lathe just to satisfy my curiosity. Have you tried knurling them with a very aggressive knurl? Yes I have. It's hard to tell in that pic but the barnes is knurled. Still blew the RCRs.

It would have to be just the right size, but it may support the plastic a little on those bullets with a radiused base. Boarhog RB did something similar. He sent me some of the .40/.50 sabots with an aluminum washer inserted. It was slightly larger than .400 and there was a cut around the inside of the sabot to accommodate the washer. Using a .40 200gr SST, my MLII took its first deer with that setup. Even at that, it was difficult to maintain accuracy. Everything had to be perfect. The washer had to be perfectly centered in the sabot. If the cut was off to one side of the sabot (talking thousandths here), it effected accuracy.
