55 grain .308 Sabot

mobil890 · Mar 14, 2021

Anybody here ever load 55 grain .308 sabot bullets for a TC 30 Herrett or any other 30 caliber rifle but mainly 30 Herrett? I came across some bullets and wondering how they perform and what dangers I might watch out for; what worked best for you. I was able to find load data online.

Don't know but they must be going smoking fast!

I remember seeing the sabots at E Arthur Brown's. I have no personal experience, but count me in on your range report! Here's a clip of some velocities:

I just loaded some up for my 300 WinMag. They were reasonably accurate at 100. Loud as hell, but surprisingly low recoil. The ONLY reason I loaded them in the 300 was because it was the only caliber I had a suggested powder for. My intent is to load them for the .308 at a later date. My grandson calls these "Lego" bullets.

Yes, I've loaded these very successfully in .308 Win. They weren't quite as accurate as .308 bullets but good enough for hunting or defense. They cycled the action normally in an M1A. Worked just fine in my Win. Model 70 too. RL7 and H-4198 are my powders for these.

I had two boxes of 20 rounds each Remington factory loads, never fired any of these. Lately I saw them sitting on a shelf, decided that since I load my own to punt them out on Gunbroker. Where they sold for a stupid ridiculous price.

Then I found another plastic box with 45 count Rem. factory rounds in it. I'd forgotten about those. I was at a WAC gun show several years ago, some dealer was selling off estate stuff. Lots of it. He had a couple of bins full of loose rounds, your pick, 10 cents apiece. I culled these 45 cartridges out of those. They're clean, look new. I guess somebody had opened boxes and dumped them out loose at some point. I may fire some of these just to compare with my handloads.

Surprised they didn't vaporize out of a .300WM.
