Background: I finally got my Underground Skunkworks, AKA Black Ops Technology, and my Thunderbeast 30P-1 together for the first time. I ordered the Skunkworks Perseus in Oct 2010 and deployed to Iraq for a six month tour. It was ready upon my return and then I put in the order for the Thunderbeast. That took eight months to get the suppressor: two months to get it to the dealer and then six fror the ATF and finally they are together - I am working on patience
This is a fine shooting rifle that Mike Bush and crew put together and it is very handy with the 20" barrel. And Bella the Collie too.
Specs:
UGSW Perseus - Left Handed
Barrel - Bartlein 1:10 - 20" - threaded 5/8 x 24 TPI
Manner's T4A Stock
Timney Trigger
USO SN3 3.2 x 17- MOA Type 1 Reticle
Thunderbeast 30P-1
Left is a 1" paster and it has 10 rounds in it and the right is 5 rounds. The accuracy is there I just need to bump the speed a tad to get up to +2550 - 2600...looks like I need to go 1/4 to 1/2 MOA left to center it.
This is my first attempt at loading for the rifle:
Winchester 748 - 44 Grains
2.835 COAL - 2.20 Ogive -
178 AMAX hits the lands at 2.845
It shot well but was a little light on FPS:
1:2530, 2:2520,3:2510, 4:2520, 5: 2506
I am going to bump it up to 44.4-44.7 and see where I go with the FPS and accuracy.
If you find yourself in the need for a build take Mike Bush and Black Ops into consideration. It is one tight rifle. The Thunderbeast works great with this rifle. This is my first thread on and I will never go with a QD again. I have QD's and this one blows it away - no comparison.
hope you guys find this entertaining
I played hookie from work today to go to the range and play...I know my boss doesn't read Sniper's Hide anyway.
