in velocity the difference between a 28 inch barrel and a 22 inch barrel might end up being as little as 50 fps.
Once your powder is completely burned I think the excess barrel is useless. I could be wrong though. I would put a 24" fluted barrel on it. Bigger calibers with more case capacity will benefit from the longer barrels.
simple straight forward question, and I would love to see a simple straight forward answer.How much difference in accuracy could there possibly be with a 22-250 between barrel lengths of 26" and 28"??
