Weatherby Ammo vs Hendershots or similar in 6.5 RPM

[CoHunter1991]

I have been shooting a 6.5 wby RPM for a few years now and it has been great. I have always used the 130g Swift Sirocco Weatherby ammo. This year I got a Garmin radar and was concerned to see my 100$ box of premium ammo produce a ES of 120 and a SD of 40 over 14 rounds. I shot Norma factory ammo which produced a ES of 40 and a SD of 16 and a set of Copper Creek rounds with a ES of 10 and SD of 3 in other calibers that same day.

I am looking for another source of 6.5 rpm ammo since i have lost some confidence in Weatherby and wondered if any of you had other success with other providers of semi custom ammo. I have had great luck with copper creek but they do not offer 6.5 RPM unless special ordered. Hendershots and Choice both offer 6.5 RPM but that's all i know of.

Thanks for the help.
