6.5 Creedmoor

7.7 twist? Who makes that and is that specific to heavies? I want to try the 153.5s, I have a 7.5.

The Berger web site has a Stability calculator that is spot on!

Yep. That is what I used when I decided not to try 153.5s in my 8 twist. The 140gr Hybrids have shot lights out for me.

Current load pushed out to 1952yds yesterday. I was alone, so no spotter and berms were damp from rain the night before…no splash. All I had was a hit indicator on target. Found the wind after my third attempt and went 4 out of 6.

41.5gr H4350, Lapua brass, CCI450s at 2760fps. Loaded at mag length. Not trying to chase velocity.

Anyone know why Lapua uses 2.717" COAL for their load data? Is that from semi-auto being part of the mix?

No idea as that is short for a semi auto too. Hornady loads their factory 140s at 2.820” and they fit in AR mags. What weight bullets?

For the Berger 140 Hybrids. My only guesses were, semi auto, or they just want you to see pressure early for their reference load. This is from their website and their Android app alike, the 2.717" COAL.

I tried some in my Seekins just to see the difference on that short length load. Rifle didn't like that jump very well compared to 2.795 - 2.805 lengths.

Not sure why anyone loading for a bolt gun would go by those numbers anyways. Measure to your lands and load accordingly.
