Just one guy’s opinion based on my limited amount of data, but it appears to me you have realistic expectations. I have an 17 Rem Ultra Wildcat w/20 inch barrel that gets 4,150 w/25 grain bullets. Friends are seeing what you hope to get from 24 inch barrels using 30 grain bullets w/the larger case 17s.
But expected velocity sometimes doesn’t materialize. I have a 22-250 that is an excellent example.
