Thread: H1000-AR2217 Difference?

Bought some H1000 month back as couldn’t get AR2217.
Finally got a load sorted with it for my 7mm rem mag, needed more powderso got some AR2217 as believed it’s same powder,

H1000 69g 3 shot group .4moa, average speed 3020fps
AR2217 69g 3 shot group 1.5 moa, average speed 2940fps

Is that likely a batch variance?
Probably not as easy as bumping the AR2217 up a touch to get same speed to get better grouping...
Or are they different and I’m best to get some H1000 as opposed to doing load development again with 2217?

Cheers
