Here are the first results from my new 12 FV in 6.5mm Creedmoor.
These were the first rounds shot from this rifle so there may be some initial 'shooting in' effect, or it just could be the rifle prefers heavier bullets.
Note the gradual improvement from the first load to the 3rd load listed.
All loads were with Lapua Brass, CCI BR-4 primers and were shot at temperatures from 34 to 37 degrees at altitude of 250 ft. above sea level.
Load Description lists, in order, powder, charge, O.A.L., velocity in fps, trim length, and wf (exit time in msec).
Exit times were at the 12th reflection for the 26-inch barrel.
The second group in the 130 grain TMK may have been the result of a loose ring screw that I was sure I tightened to 30 in-lbs. with my old Fat Wrench.
I would have just chalked it off to 75 year old forgetfulness but the same thing happened on the scope rings on a new scope that I know I tightened with the same Fat Wrench on the new 12 FV .223 that is listed in another post. I think that my Fat Wrench may have have been jostled a bit too much from banging around 8 years in my range bag.
