What's skinny on this new bullet, Just ordered some from Sinclair to test in my 7mmWSM.
Anybody play with these yet??

First I have heard of them. I'm gonna have to try some.

It's a mix between the tangent and secant ogives. It's supposed to help with stability all while still keeping a really high BC. I've shot them out to 500 but no farther. They certainly do as well at that range out of my 7WSM as do the 180 VLD's. But, between the two there isn't going to be a lot of difference mathematically.

The 7mm VLD Quickload library length is 1.081", but I just got a batch of 1.253".
My 7mm 180 VLD are 1.533 long, and the library shows 1.525".
So verify the length of your VLD bullet, boat tail, and boat tail diameter.
To change bullet dimentions in the library the menu path is:
Data: Add, Change, Load, Save
....Projectile/Bullet data
.........Change data records in active file

PM Skyking. IIRC, he's used them. Can't find the thread. Seems his LR elevations were the same as the STD.

Like the guy above states, they're the new 'hybrids' that allow one to NOT have to jam the lands, as with a secant/VLD design. I don't know if they're really going to fly any better, but you'll be able to jump them some and this will ultimately make things easier on the reloading end.

Re: New Berger 7mm 175gr match XLD bullets???
These are not the new hybrids. The hybrids are 180 grains. These are a different design.
Here's a post from Eric.
For the sake of clarity, the 7mm X Bullets as they have come to be known were developed for a military opportunity that did not pan out. The goal was to produce a 7mm bullet that will stay supersonic at 1 mile (I don't recall at what MV). Since we did not know which design and weight would accomplish this goal we decided to make all three (VLD, tangent or BT and Hybrid). When the dust settled the Hybrid produced the highest BC.
We made short runs of these bullets for testing and spread them around to see how they shoot. Frankly, it was our intension to see which one shot the best. The plan was to add one version to the line and moth ball the other two designs with our other experimental project that did not make it into the line. The problem is all 3 bullets performed well in testing. One design out shot the other two for one tester but not by much and another tester reported that a different design worked best for them.
The 180 gr Hybrid, having the highest BC, is proving to be the front runner so far but it is not head and shoulders above the others. So I am left with two general directions. The first is to stick to the plan to release just one design or to release two or three designs and see what happens. I decided on the later. Unfortunately, we did not have the jackets needed to make more than the initial test quantities. We are making 7mm jackets but they are the standard thickness for the hunting bullets.
We should be finished with these jackets in the next 3-4 weeks and will be switching to the thick jackets as soon as possible. We will be making large quantities of each version and will let all of you decide which 7mm heavy bullet rules the roost. When these bullets become available there will be 5 versions to choose from.
28404 - 7mm 180 gr BT (Medium Tangent Ogive) - G7 = .314
28405 - 7mm 180 gr VLD (Long Secant Ogive) - G7 = .337
28406 - 7mm 182 gr XBT (Extra Long Tangent Ogive) - G7 = .332
28407 - 7mm 180 gr Hyb (Extra Long Hybrid Ogive) - G7 = .345
28408 - 7mm 175 gr XLD (Extra Long Secant Ogive) - G7 = .336

Re: New Berger 7mm 175gr match XLD bullets???
Jumpalot,
That's good information to hear. What I had gleaned is from trying to put 2 and 2 together from what I read here, on the Berger Website and other reports. I, personally, was one that totally protested the 50 mil contract to Federal to produce x-number of rounds in .300 WM loaded w/220 gr. rounds. Which took out of the running a better bullet for "in-transonic" running in 7mm.
I know, somehow I feel like I'm fighting city hall.

Re: New Berger 7mm 175gr match XLD bullets???
So if the 175s are an extra long secant ogive, they're better off jamming the lands, like your regular VLDs?
Thanks for correcting me. I knew you had hybrids out there, just didn't know the labeling. Berger's labeling can be quite confusing.
