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.

Do you handload?

For the money you are spending in boxed 6.5 RPM you could set yourself up nicely.

The RPM loads pretty easily and mine likes TTSX and Hammer monolithics.

I don't see any reference to group size in your post, only velocity spread. I'd say if the groups are small the game won't notice 120 fps.

If it worked great before then knowing it has poor ES and SD doesn’t make it shoot any worse. If you’re not shooting over 500 yards then it won’t matter anyway.

I wish I had the time to hand load. Right now it’s not in my cards

Yeah my groups are sitting around 1/2-3/4 with 5 shot groups.

I just missed an antelope at 425 this past week and even though I’m 99.9% sure it was me that caused the miss the .1% chance I caught a hot round is on my mind. I’m just hoping for more consistency out of a 100$ box of ammo

How has the WBY ammo usually shot at 435? That SD and ES are really poor, so I fully understand wanting to find something else.
