[QUOTE="Max Heat, post: 636828, member: 43153"] If I recall correctly, the 30-06 accelerator launched the 55's at 4,000fps. That's exactly the sort of "fast" I want, only with 2 to 3 times as much lead as a 55 grainer. I do recall that the accelerators really sucked, as far as accuracy goes. But they ran .224 through a .308 bore. I believe that the larger the gap that the sabot needs to fill, the worse the accuracy will be. That's why I thought running .257 through a .284 bore would make more sense, accuracy-wise. And it would allow me to stay with same bullet weight, but have better ballistics, for the really long range shots. Granted, a 7mm 195gr VLD WILL outperform a 120 or 140gr 6.5. But it is at the cost of significantly less velocity, and significantly more recoil. Plus, you'd need a custom twist rate to run those. I'm wondering why BR uses 6.5, rather than 7. I think I might want to try BR, but would like to have some kind of advantage going into it. As long as I was firing 6.5mm bullets, I would not violate the regulations, but would have the advantage of velocity (flatness) over everyone else, right? BTW - There ARE 2 companies that I know of who are currently developing sabots for reloading use. But the reloader will need to purchase a special tool for seating the bullets into the sabots. I think it will be fairly inexpensive though. As far as I know, they will be offering .224 for .308 (naturally), .224 for .284, and several others. I'm hoping that .243 for .284 will be one of them. I'm not holding my breath for a .257 for .284 sabot though. [/QUOTE]
