Well I finally got my rifle together. 24" Barlein (chambered and shouldered by Bugholes), RV contour, 1:7, Origin, KRG Bravo, Burris 5-25XTRII.
I fretted neck diameter (supposed to have a .255" neck) as I wanted to be at .252" loaded. I played with my neck turning kit on Virgin Brass and finally just figured I was overthinking it.
I took the 7 cases on whose necks I had been playing with, loaded 30 grains of LeverRevolution and a 450, seated 88's to 2.370" OAL (.080" throat) and went to the range. I ran 3 over the chrony at about 12'. It read 2924, 2961, and 2904. The spread could be due to the loads, the fact it was raining on my chrony, or the fact it's just a cheap shooting chrony, it didn't really matter, I just wanted to be sure I was at or below 3000fps, unsuppressed. Temp was around 65-68 deg., FWIW. Sighted in at 100 yards with the other 4.
I sized 25 necks down on a Redding FL sizer (took the expander ball out, sized down, then ran the necks back UP on the expander ball) and left a slight shoulder on the neck (.050-.060 or so). This did make them a bit tough to chamber, so I'll try do a bit less shoulder on the next batch.
Went to a friend's farm yesterday where we had our annual muzzleloader and rifle sight in. Broke out the .22BR and it put 5 rounds into two holes for group that looked a touch under .5" (100 yards).
The only issue I'm sorta concerned about is I've a slight ejector slot mark on some of my brass (about half the fired loads). I really doubt the loads too hot, I've got an A Bolt .25-06 that'll put an ejector mark on factory ammo, so I'm not sweating it too much.
Thus far, I'm in love. I know that one, five round 1/2 inch group at a hundred doesn't mean much in the company that's on here. But for the first load I spitballed down the barrel, I'm pretty tickled. Gonna get a few more loaded and try to get it out to 600 and possibly 1000 yards next week.
