Anybody have any experience loading 22 sabot loads in your 30-cal rifle? I got some plastic sabots for use with 60gr 22 bullets in 30-cal rifles. Tried to load some up tonight for my 30-30, but with very little success. The sabots have such a sharp heel that if the case neck is not flared a little, then the sabot won't go into the case. It just mashes down and crumples the case neck instead, destroying the case.
And load data? Well...they just give a "computer-generated reference data" loading sheet, no real shooting bench feedback and experience. They just say to start with "light loads" and work up. Ok, while that may sound good, what is a light load for a sabot? 5% under? 10% under? 15% under? Why didn't they go to the shooting bench, and find out for us if their "computer-generated reference data" loads work? How hard could it be to send one of their workers to the range for a few days, and test their data before selling their product to the public? I get this feeling they are kinda guessing a bit at this...
I don't care about maximum velocity, just something that will group reasonably is fine. If I can get 2800-3000fps or so, then that is good enough. I was going to use IMR4198; is there a better powder for these extremely light bullets in a 30-30? How about the 30-06?
This is the outfit I got the sabots from: http://www.eabco.com/Reports/report04.html
If you used these (or any other brand sabots), what did you think of them?
