Is that the Tipped Sierra you’re talking about? Doesn’t look to fit an AR mag without compressing the load.

I used Sierra 130 gr. bullets and TAC 26.5 gr. powder with very good results on a AR platform rifle…

Im really enjoying the power pro varmint on 130 Berger 130 hybrid ar otm . Getting sub moa groups out of 24″ Lilja in ar15. I’m at 28.6gn with light ejector marks . Way better accuracy than cfe223 in my firearm . The accuracy is still better with 8208xbr ,but you’ll sacrifice velocity .

John, I asked about AR-Comp on sierra’s facebook post and was advised that it is currently in testing so an update will be coming soon.

Adam, open the link to sierra’s blog and you will find more than just the 107

Why no 107gr data?

I am wondering if these loads are for AR-15 Style rifles or bolt action rifles. Ie loaded to 50000 or 60,000 PSI?

Thanks, Sierra, for doing this. Power Pro Varmint seems to be a solid powder across the board that the Grendel community hasn’t explored.

I’d like to see some of the most obvious and common 6.5 Grendel powders also tested: CFE, ARComp, AA2520, and LVR.
