Low tech farting around comparing capacities using AA-2230 to the bottom of the necks, the 22x47 has a grain and a half advantage over a 22-250 in fired brass. Likely more if I'd only gone to the shoulder.
The 22-250 has around .050" total case taper with a 28* shoulder, the 47 has .013 taper and a 30* shoulder angle. Damn close to a factory "Improved" case

That 80 grain .224" Berger is a great killing bullet too... I've got high hopes...... Killed a half dozen coyotes last year with them, & they worked great, but I'm adding another 350 FPS to the mix.

My 6x47 is quite simply the most accurate gun I've ever owned. Next gun I put together will be a 7x47 lapua. Love that gun you have there.

So load work consisted of the 80 VLD's in the lands, and three powders that I had on the shelf, Varget, H-4350, and H4831-SC. Based on research, and past experience with a 22-250 AI, I figured the H-4350 was the place to be, but I wanted to explore both sides of it, speed wise. An extra 6.5-20x50 LRT Leupold was mounted up, and testing commenced.
As figured, 4831 was a touch too slow, and crunching powder before reaching top velocity. I found a good load with the other pair, so I had a shoot off between them, while testing bullet seating at the same time. I found pretty good accuracy at .060" off, but it still didn't match in the lands. When the smoke cleared, H-4350 with the Bergers in the lands won out.
Final check to confirm shows I made the right choice:

The wind got a little sporty by the time I got back to 400, but the minimal vertical is the standout feature:

I've got others more suited for PD's I could toss in the truck that won't trash the barrel in one outing. Would make a cool twofer hunt if the weather would cooperate.

Holy balls....nice rig aalf, I guess I need to try some 80gr. Bergers. Thanks..... Got alot of experience with 75 VLD's at 3075 on coyotes....great performance. Stepped up to the 80's at 3025 for a handful last winter w/equal results. Typical small exit on broadside shots. Not sure whether to expect a big/bigger/huge mess stepping up the velocity, or maybe staying inside. Doesn't matter around here for hides, but can/does when I head west.
