7mm Rem Mag and Magpro for 150 NABLR?

[pharmseller]

Anyone use Magpro in 7 Rem Mag with 150 NABLR? My brother has a 7 Mag on the way and I have a bunch of 150 NABLR to try.

I'm using my 150 grain ABLR in other cartridges. I may focus on the 168 grain ABLR at some point in the future. However, my 7RM is performing quite well with 160 grain AB and 175 grain PT, so I likely won't be making a change. However, I can't imagine that this wouldn't make a fine load.

I ran some Magpro in my 7WSM and 168 ABLR's. Did real good with that. Currently running MRP with Swift Scirocco's which shoot pretty well. Magpro has always been a good powder for me in the WSM's and the 7mm Rem Mag as well.
