It's right there near the same burn rate, albeit ever so slightly slower. GRT prediction with a 105gr, well over 90% case fill with my measured cases, mid 90's burn rate, efficiency 29% with a more room to go before peak pressure (gas gun).

Varget works great in my gun. A little slower velocities than Lever but better accuracy. The new StaBall match seems to be close to Varget also but a ball powder. The few people I've seen try it shows promise.
