That tempts me to play around with RL17 since its very close to H4350 but with some inhibitors for the short mag cases. Though it’s not very temp stable. I have RL25 and have been waiting for H1000/Retumbo to show up anywhere. Lots of great data on 7mm RSAUM here at AS so I’m sure I’ll find something that works :)

It is a faster burning powder, however you will use much less of course.

FWIW: While it is a very consistent powder through varying temperatures 15 to 35 degrees Celcius, the extra space left in the case could be detrimental to consistency.

Personally I run H1000, which fills the case nicely, and I find it to be super accurate with the Hybrids. After all 12 Super V’s out of 15 shots all in the center when fired over 800 yards should mean something.

As with all calibres, experiment with various components, and find what works consistently with your barrel. After all, there is no 1 perfect solution that fits all barrels.

That seems like an awfully fast powder for that load in a 7mm RSAUM, what am I missing? I ask because I’m having Mark Chanlynn build me a custom 7mm RSAUM as I write and I will be working up loads soon…

It has been down ever since.

I shoot with very little pressure on the cheekpiece.

Congrats on the win

Every picture I see of his rifle seems to be missing the cheek piece… :-)
