I buy them all the time. I try and save up for a big order because they are probably going to ding you about $12 for shipping no matter how big the order. With the price of bullets going up it doesn't hurt to have a little "stock".
I can never tell the diff between blems and firsts. I've been told that if something comes down the line with a stain or discoloration they scoop up a bunch and put them aside. They are not physically damaged. I've never even seen a stain. Sometimes I wonder if they are even first quality because I think nosler would still make good money at those prices because they are selling direct.
Anyhow....I would recomend you buy some. I saw a group posted on another forum by a guy by the name of POP who shot a 3/4" 300 yd group with the 200AB.....couldn't have been too bad of bullets.
By the way...noslers brass is very high quality...I buy blems there too!
Mine shot great at 94g H1000 w/200g AB which gave me right at 3200fps. I was using a factory 26" rem pipe myself with an OAL of 3.660". 92g was also pretty accurate at 3100fps. I would bet your in that 3100-3200fps range.
94g H-1000 was pretty much the safe max load in my rifle with the 200g AB.
