That is good- Varget and H4895 are really close in most rifles- with Varget being just a tich slower. H4895 also works to as low as 60% of the normal full power load whereas many powders do not.

WW can be heat treated to withstand ANY velocity range if you want. This is due to the antimony and smidgen of arsenic - arsenic being necessary for the hardening process to be a success. That means pure lead/tin mixes cannot be hardened further. The WW MUST with NO ZINC content - a newly acquired bucket of WW must be gone through to discard any with a "Z" on them - or many that are 'too light' to be real antimony/lead mix - or any that are stick-on weights.
The stick-on weights can be either pure lead or zinc as well.

Zinc will ruin some lead pots as it infiltrates the pores, cracks in fouling, etc, then leeches out into the mix - wrecking it - & casting poorly filled out bullets.
