first 3 groups at 300 yards,,switched to my trusty load testing scope,,an old M8 24X Leuold with fine cross hair,,the Bartlien barrel doesnt seem to fussy and cleans up easy,the Stiller action seems to work fine and feeds off the AI mags just fine,,

shot off the Atlas bipod and a rear bag off a bench,,

without doubt the smoothest shooting rifle I have ever owned myself,,

orange dots measure .815






 
I cant wait to get the Lapua brass through its first cycle and start really working up a load with once fired fully prepped brass and get to use my new Redding Competition Bushing size die,,I been loading so far with new brass straight out of the blue box,,

Yep extremely good shooting.

You gonna go all out on the case prep?

I am gonna uniform flash holes and primer pockets,,so far I have measured the necks of the cases I have loaded and all have been 12 and a half thousandths,,I might clean them up to 12 even but havent decided on that yet,,will trim them all after I get them once fired and will weight them to see if they need sorted,,

the groups at 300 so far have 4 pretty tight with one out a bit,,mirage was bad also though and I havent messed with seating depth either,,or found any H4350 which most everybody shoots with the 140`s,,
 
I resized 20 cases and loaded 123 Scenars with Varget starting at 37.4 grs and ever .2 grs up to 41 and gonna shoot a optimum charge weight test at 300 next time the conditions are in my favor,,I cant find H4350 so I am gonna change bullets to match the powder I can get,,

the extra speed overcomes the higher BC in the wind out to 800 yards or so and the 123 is actually flatter past 1100 yards,,
I am gonna shelve the 140`s until I stumble across some H4350,
