, I don't know exactly what you are talking about, so if you want me to look up something specific and will tell me what to look for, I'll take a peek.new S+W cartridges
ole...I've got one. Kind of concerned about some of the data though. They list 62 gr. of H4831 with the 130 in a 270 Win. Most everybody else has backed off to below 60 these days. They do have +P loads for the 257 Roberts, but are below some of the more accepted loads.
Of the loads I've really looked at they are well above what Nosler lists in their latest. May be just those particular loads though.
