7mm-08 QL data?

Tjay · Aug 25, 2022

Thanks DrMike I also have a 7-08 so the info will help me also.

I've been wanting to try cfe 223 in my 7mm-08 with 120gr TTSX for a long time now. I just recently saw that cfe 223 is available after the great famine of '19! I still don't have any on hand, but what I am going to try with 120's here pretty soon is Leverevolution. The same burn rate or just a touch slower than cfe 223. Should be interesting...

big game works great with 140-150 grain bullets, I'd like to see how it does with a 120.

Leverevolution has so many applications where it performs admirably outside of what it's name would lead you to think where it should be used. I use it in my Grendels and 223's with excellent results. It is right there with my CFE loads with the 64 BSB in 223.

Might be worth a try.

I've been playing with it in my .223 as well. Excellent velocity and accuracy looks promising but still working on the various loads.
