Reloading for the 6.5-300 weatherby.

Has anyone done any reloading for the new 6.5-300 Weatherby??

Yes

Yes, have recently worked up a load for the 156 bergers, can't remember the speed but n570 seemed best. 869 was a dud. Needs a tougher bullet if going light

GOOD LOARD what MV/FPS you getting may I ask? My best guess would be closer to 3500 than 3400.

I honestly can't remember for sure, I'm off tomorrow and will take a peek. I think it was only like 3250? @ max bergers suggested charge. Am going to use a tuner for groups

So , 2 shot velocity ladder, 3137 and 3142 with 77.5 gr n570 @ 3.621 coal out of 26" vanguard 61 degrees at about 600-700 elevation western Washington. Think Berger said this was 95% fill which felt about right by shake lol. They said they only got 3060 with same charge. Slight crater and flattened primer. They also said this was they're fastest combo. I was surprised by low velocity with 869. Pretty sure I tried lrt as well with not any better results. My velocities never seem to match internet speeds though so maybe it's my elevation and area. Might be a while before I get a chance to tune and shoot distance. Having a heat wave here. Hope this helps

That's slow . I can comfortably break 3,000 FPS with 57grs of N565 in my 6.5 PRC ,still have room to push it .

I loaded 127 LRX, 140 AB, 140 VLD and 129 Hornady using US869 and H1000. It shot well with 127 at 3333 FPS, the 129 Hornady and 140 AB did well also.
