Berger 130 grain Hybrid
As I was looking at the Berger Bullets website, I happened to notice a new .277 130 grain "hybrid" hunting bullet on their PDF listing all of their bullets:

For those who don't follow developments in for competitive precision shooting, the Berger "hybrid" design combines a secant ogive at the tip for low drag, and transitions to a tangent ogive at the rear where the rifling engages. The goal is to make a low-drag, accurate bullet that is less sensitive to variations of the jump from the cartridge to the rifling.

The numbers look impressive, but I could not find a picture of the thing. At first glance, the ballistics look even better than the 140. Three questions that occur to me are:
1) Is the listing a misprint?
2) How well will it fit in a loaded 6.8 SPC cartridge?
3)When will it be available?
Sorry if this has been discussed before (I've been sick for while).

A plan is just a list of things that doesn't happen.
I don't reload but it seems like 1.22" is too long.
Sorry guys, I may have jumped the gun on this one (I've always wanted to say that on a firearms forum). Last night, I read the chart wrong. The nose of the Hybrid round is significantly longer than for the 140 VLD (which seems to be about the maximum for 6.8 AR magazines).
Here is the comparison of 130hybrid/ 140 VLD:
Nose length: 0.670" / 0.618
OAL: 1.220" /1.45"
Boat tail: 0.220" / 0.210"
Base to ogive: 0.550" / 0.627"
Bearing surface: 0.330" / 0.0.417"
G1 BC: 0.297 / 0.487
G7 BC: 0.254 / 0.248
This may still be OK for with bolt guns, or when loading single shot.
When I first read the table, something did not quite make sense to me about the lengths, but I was apparently looking at some of the the wrong columns.
To bedlamite: I had thought of looking at the Midway site, but then I thought :"Nah, if it is not on Berger's site, why bother." Thinking, it seems, often gets me into trouble.
I have some of the 130 gr. VLD. Glad I have them and not the Hybrid because of the length.

I take it these would be great for tactical loads...
I'm thinking I would like to try these in my 23" saami spec 1-10" twist T/C Contender carbine barrel.
If I could push them to 2450fps - 2500fps I'd be good for deer size game out to 350 yards.
Looks like these are the only 277" Berger bullets listed for the 1-10" twist barrels.
The 130 VLDs are supposed to be used in 11 twist or faster, 10 twist is faster than 11.Originally Posted by Camp Cook

You are completely right = I'll say what I was trying to say differently the 130gr & 140gr hunting VLD's are listed for a 1-11" twist the 130gr Hybrid is listed for a 1-10" twist.
I edited that last line in quickly after I posted the first 2 lines wasn't thinking how it read.
