A quick search on LRH would have revealed that Cheytac has only 44 posts and joined in May 2009. The small number of posts is not problematic, but the fact that nearly all of them were to sell/buy equipment would have been a caution sign for me. He is not what I would consider an active participant in the LRH game.
If you are referring to his ad to sell 300 WSM
Norma brass, then he should make it right. The way the ad is written, it leaves the reader believing that it is all new Norma brass in 50 ct. bags. There is no mention of used or loaded brass or mixed headstamp in the ad.
