Need help from the 7mm fans

[Xcountryrider]

I'm gathering data on 7mm bullets for a community wildcat project called the 7mm Valkyrie AR. The project is to design a wildcat in 7mm for the AR-15 with the goal of gettting near to or match 7mm08 velocities for the AR-15 platform. The parent case is 6.5X47 Lapua. Think of it being a shorter 7mm08 with about 42gr of H20 Capacity. I'm gathering data on all the 7mm pills that would be appropriate to load. These are the ones i have not found the length/OAL of the bullet for. Here's my spreadsheet of bullets i have data on.


Sierra HP HP 100gr
Speer TNT VarmintJacketed HP 110gr
Hornady HP HP 120gr
Sierra Pro Hunter SPT 120gr
Sierra Match King HPBT 130gr
Speer Hotcore SP Spitzer 130gr
North Fork Tech SS SP 130gr
Federal Fusion Bonded SP 140gr
Swift A frame AF/SS Partition 140gr
Woodleigh Weldcore Protected SP 140gr
Speer Grand Slam SP 145gr
Speer Hotcore SP Spitzer 145gr
Speer Match HP Match 145gr
Sierra Game King SBT 150gr
Remington CoreLokt SP 150gr
Hornady Interlock Secant Ogive 154gr
Federal Fusion Bonded SPBT 160gr
Swift A frame AF/SS Partition 160gr
Speer Hotcore SP Spitzer 160gr
Hornady Interlock Secant Ogive 162gr

How different from 7mm TCU?

And is it really necessary with the weight and price falling on .308AR Platform?

From someone who just ditched .270AR which is almost .308 power in the AR15

I have a 270AR didn't ditch it but with the 7mmVAR you get a much better selection of high BC bullets and can load up to 160gr. Initial testing this weekend by the team lead with a 24in barrel shows velocities in the 2800fps range for 140gr BT. We aren't commercial we are a project to get a caliber we like for hunting in the lighter weight AR-15. The new Hornady Lock N Load Neck turn Tool has made neck turning super easy so case prep isn;t a pain anymore. Its just a matter of the right tools. I'm not trying to talk you into it i'm really just looking for bullet measurements. Like i said this is a community project.

The introduction of the Hornady Lock N Load neck turning tool last month made the hard part neck turning way easier.

Hey I have had great luck with CFE 223 powder in my 7mm-08, pushing 140grs past 3000fps. Just FYI. Maybe worth a try. Might help ur marketing anyways if u can push them faster then comercial ammo. I havnt tried magnum primers yet cause my sd's are like 12-16 but I do see a small bit of what looks like unburned powder, but on the other hand it might just be the "copper fouling inhibitors" im seeing. I will try magnums sooner or later.

My fav load so far is with 120gr Nosler BT's at a a screaming 3300fps from my 700. Under half MOA. Running at 49grs of CFE223. But be carefull it's a STOUT load. I only run it on winchester brass that's been fire formed, running it on virgin brass scares me. PROCEDE WITH CAUTION.
Lol

We are using CFE and Lever to get them to normal 7mm08 factory loads . We have less case capaciy so that brass would fit in an AR-15. I'm just one of the guys that help funded the project to get a barrel to build one.

Sweet. Hey if could share some of ur lever data I would appreciate it. I have always wanted to try leverevolution in the 7-08 but data is scarece. Pm me so I don't hijack ur thread. Lol

I would give some readings but I just don't have any of those pills ur missing.
Good luck.

I have not gotten the 7mm Valkyrie AR barrel yet and the lever loads would be different in the 7mm08 different case capacity. The lead designer is testing right now i'm 2 months out on my barrel.

I got what i needed thks.
