So, I finished my loads for a next test, got now in my hands shippings of both varget and shooting world precision rifle.
The latter does not have silvery color of varget nor its smell - color is rather dark and a 24.8gn measure setting for varget seemingly produced 24.4gn load of precision rifle.
Sticks are slightly smaller than vargets’, so it may be less compressed in any 24.5+ loads compared to varget, but, will see. I ran out of prepped primered brass, so will do a comparison test next time.
