Always used Lapua 220 Russian but it's unavailable,
New barrel and old Lapua brass was giving clickers so I came onto some new Norma. Out of the box the shoulders are .0035 short of the fired Lapua brass out of this barrel which is .001 shorter than where I would have sized it to but close enough, with a bullet seated the necks measure .2658 and my chamber is a .268 so that should work also.
It is almost 3 grains lighter so I figure I'll have to retune the load.
I loaded up 5 rounds with exact same load from the Lapua brass that was at 3420 and they went 3390 and 4 went in group with 1 outlier ,, I bumped powder up a little and shot 5 more that went back up to 3420 and all went in group. So I loaded 6 more and shot the rest of target.
Not too shabby for no prep and loaded straight out the box.
Guess I'll load up and shoot a match Saturday with brass straight out the box. Wish me luck. lol
