My post doesn't mention the $2 you refer to but I do consider $67 for 25 rounds of 338 RUM brass to be a good deal only if someone is in desperate need of brass. Its all about supply & demand. Others may have a difference of opinion on that. My comment was not a reference to you if that is how you took it.
Don't understand your question re: shooting a 338 RUM at 300yds. Is that too long, too short, or just not right in your opinion?
Either way, my point was obvious. When shooting a rifle of known accuracy at 300yds, the groups shot using Rem brass were just as small as the groups shooting Nosler brass which cost more than twice the price.
