I went to ThunderValley today and shot my 10.5 inch 6.5 Grendel full Alexander arms build out to 1k. This was off a front bag and a brace on the back, which is not a very stable plat form Only thing changed on the grendel was the trigger. I was shooting 123 eld-m and was averaging 2316 putting my transonic out to 1075.

I shot 10 rounds out to 1k I had a 10-15 mile an hour swirling wind. 400 wind was showing 7:30 1k flag was showing full value to 3. 1 mile wind flag was wrapping it self around the pole. Welcome to Thunder Valley..... Also this was in a down poor.


Scope eotech 1-10........

3-10 rounds impacted......... lots of rounds off right and left edge. I would easily say 8-10 would have hit a full larue. I have shooting at a 12 inch square.

I has the same muzzle energy as a 9mm at point blank. Impressed to say the least.
 
Out of curiosity, what load is getting you 2,316 fps out of 10.5"? That's a pretty fast load, only about 100 fps behind what top end 8208 and AR-Comp loads give me in a 16".
