Shot purty hard this evening with a bunch of stuff,but the Newest Bitch done fine. Hint.

Fired (2) rounds from the hip this morning,looking for pressure and liked what I saw,so loaded 50rds. All prior to it seeing a ring,rail or scope. Hint.



Then tore it apart for a cursory inspection and found the typical tattle tales,but let 'em ride if only in the interest of R&D. Hint.





Slammed a NightFarce steel 40MoMo rail aboard,trial fit glass/rings and had to shorten the rail for objective clearance,which is a GOOD thing. Gooped the works,slammed it tight,ran a cursory boresight on an Iggle Nest out the kitchen window and was ready to make empties. Hint.





Long story short,I missed my velocity prediction by right at 25fps,as the 1300yd steel was actually a 10.2 Mil correction,which is .2 more than my supposition cast yesterday,prior to even seating the first primer. All things considered,I don't beat myself up when a Mystic Velocity Assertion is off by less than 1%. I'd attribute the discrepency to both a new Lot of powder(slower),a touch looser than usual bore and that despite a throat shorter than most. Only slid the proposed velocity and let BC roll. Hint.




In fairness and counting the (2) pressure test hip shots,it was a total of 8rds to assert same. Fired (2) of those at 970yds. Sadly,no Cardboard ChooChoo was incorporated and it took but a coupla seconds to input the Mystic Velocity Assertion's actual and backtrack come-ups to the muzzle. Pard was shaking his fhuqking head,so I had him follow suit. 100yd boresight paper was easily resolved by FFP Gen2 Milscale Spotter(fhuqking POS Reupold MK4). FUNNIEST part was,I actually got the Goat Fhuqk X-Mark trigger to behave! Hint.



Not that I don't enjoy how folks make this schit difficult. This Rifle is yet another Myth Buster and the "surprises" none. Weather sucks too. Hint.

LAUGHING!..............

Oh crap ! ! !
You can't put any thread locker on scope mounting
hardware ! ! !
Other people don't like that.
They might get unhappy with you.

Leaving the BC alone and slightly altering the MV when supersonic seems to be the rule of thumb. Subsonic or transonic tweaks can be tweaked with the BC. This is if I read Litz correctly. Same for using the G7 with low drag bullets.

I ended up lowering my MV 1.8% and left the Litz G7 alone. It seemed to really line things up at my max range of 550. Looking forward to extending the range past that but for now it is as far as I have to shoot.
