95 NBT is my go to in 6BR and 243 for all ranges, in a 240 I might go 80 TTSX.......but longer shots Mono needs speed to expand.....
A Swift 90 might be more reliable than those Noz that might not be bonded. Really high speeds put a lot of stress on bullets....
Partitions will be a bit slower if 100gr and do well to most normal shots in your 240.
In that case capacity - personally I'd rather a 6.5 or 7mm bore.
