Can you move a 50 or 53 grain V-Max at 22-250 speeds, out of a fast twist barrel, and not worry about the bullet coming apart in flight?
Looking at a rebarrel, love the lighter V-Max's, but would like a faster twist so the heavies are an option.

My old Remington 788 in .223 Rem. was 1:12 and it stabilzed 60 grain bullets ok. But most .22-250s are really slow twist 1:14s. They're great for the 40-55 o grain bullets. I don't know how 40-50 grain bullets would do with a 1:7-1:8 twist though. They would come out humming they'd be spinning so fast. Maybe a compromise of 1:9 would be good. My 1:9 Savage stabilizes 68 grains ok, but I don't think I'd go any heavier. And as I understand it, it's not weight so much as length. There's differences in the BC. One 68 grain bullet may have a higher BC than another. Thus one may stabilize in a 1:10 twist and another may not. There's guide lines for what twist will stabilize x grain bullet but there are other variables to consider. So if it's me I will give it plenty of room and not ask a whole lot. If I want to shoot mostly light low BC bullets I won't build a rifle with a real tight twist and if I want to shoot the heavies I'll build it with a fast twist and I won't expect it to preform well with all bullets. You can only compromise so far.
